editor’s Letter The World is Our Oyster

In the 1980s, the new wave band Frankie Goes to Hollywood released an album with its second track titled “The World is My Oyster.” The song is all of one minute long, but has been sampled in a variety of decadently-indulgent remixes—including Frankie’s own works—that this editor and child of the ’80s finds “groovy.” Why should I bring a 34-year-old musical aside to the beginning of the World of Asphalt/Agg1 2018 edition of an asphalt industry publication? Because the oyster sits before us right now Editor Sandy Lender with a big, fat pearl of opportunity inside. The Association of Equipment Manufacturers (AEM) prac- shared transportation tically wrote this column for me when they reported 10 pre- funding thoughts with dictions for infrastructure development and growth after the Rep. Daniel Webster State of the Union address. The trends they highlighted stem (R-Fla.) during the from optimism and a positive outlook. The industry is abuzz August recess. with energy and forward momentum. Take a look at the positive trends AEM believes TRC Companies—an engineering, environmental consulting and construction management services firm—has got right on the money. First, AEM and TRC believe “[i]nfrastructure spending will intensify as a result of comprehensive federal infrastructure legislation potentially bankrolling projects both big and small across the entire country.” Second, they believe “[s]tates will rely on alternative approaches to planning and construction to pay for their projects. This could include more design/build transportation projects or more public-private partnerships.” They anticipate trends toward greater renewable sources of energy and higher priority for energy storage, as well as a push for smart grids from utilities and regulators. You can check out the article “Vary Energy Use” in the January issue for some tips on that concept. An unsettling trend they reported, and which our industry has been trying to cut off at the pass, pertains to the labor pool. “There will be a boom in projects in some states that will prompt labor shortages across the board. This will, in turn, lead to delays for many companies if they don’t plan for this challenge.” Also watch for “[t]echnological advancements [that] lead to increased air quality monitoring.” It’s apparent the asphalt industry has a busy season coming up. This is the time to invest in employee development, safety training, equipment, components, innovations, and the business elements that will catapult you to the front of the bidding line. Carpe diem. No grit, no pearl. Shuck the oyster. Stay Safe,

UNITED STATES Forty states added construction jobs between November 2016 and November 2017, while 39 states added construction jobs between October and November, according to an analysis by the Associated General Contractors of America of Labor Department data released Dec. 22, 2017. Association officials noted that firms in most states are adding jobs amid expectations that demand will continue to grow thanks to new tax cuts and regulatory reforms. Association officials noted that many construction firms have high expectations for the coming year. They said that as they prepare an annual construction industry outlook, it is clear many firms expect the administration’s efforts to reduce regulatory burdens and newly enacted tax cuts will further improve market conditions. “This is one of the best business climates many firms have experienced in over a decade,” AGC CEO Stephen E. Sandherr said. “While Washington needs to address infrastructure funding, workforce shortages and multi-employer retirement reforms, 2018 looks to be a strong year for the industry.” Source: AGC 8 // March/april 2018

Save Your Back O

One of the clichés we use in language is to call something “the backbone” of an entity. If a person is dependable and integral to holding an organization together, we call her the backbone of the company. It’s a compliment. It’s based on a vital component within our bodies: the spine. Our care of this central system is vital. Strangely, citizens in North America experience back problems that result in disability to an alarming extent. The Bill and Melinda Gates Foundation funded a study that showed in 2013, the world’s top source and burden of disability is low back pain, and the world’s fourth highest source and burden of disability is neck pain. This disability was most burdensome in North America, according to the Foundation study. To protect the spine from injury, workers have the responsibility to strengthen the muscles around it, reduce the potential for strains by maintaining flexibility, warm up muscles before work begins, and practice proper lifting and moving techniques.

The Department of Defense offers injury prevention strategies at https:// www.hprc-online.org/articles/injuryprevention-strategies-avoid-back-pain including proper lifting techniques. Step 1. Plan the lift. (Ask for help if an object seems too heavy for one person.) Step 2. Face the object directly; don’t twist at the trunk. Step 3. Bend at your knees, not at your waist. Step 4. Keep the load as close to your body as is safely possible. Danielle Browne is a Certified Strength and Conditioning Specialist® with Vivecorp Inc., who offered ideas for warming up muscles before work begins. “Chances are if you’re reading this, your job is physical in nature. Like an athlete who warms-up to prepare for a game, a warm-up prepares your body for the physical activity of your job. A warm-up is designed to increase your core temperature, improve coordina-

tion, elasticity and contractibility of muscles, and increase efficiency of the respiratory and cardiovascular systems. “In short, it prepares your body (and brain) for the day ahead. Think of your body like a piece of taffy. If you try to bend taffy when it’s cold, it breaks. But if you spend a moment warming it up, it moves much more easily. “When warming up, engage major muscle groups. Think dynamic movements (arm circles) vs. static movements (toe touch). Don’t feel like your warm-up needs to mimic your job function exactly—do movements to strengthen or correct muscle imbalances.” Browne shared how warming up is a preventive measure. “Most job functions and activities of daily living put a strain on the entire back—especially the lower back. But muscles of the back don’t work in a vacuum. They work in synergy with the rest of the body. Imbalances or weak areas anywhere in the body can cause injury, especially in the back. “A good warm-up will include strengthening and range of motion exercises for posterior muscles which tend to be tight and weak, like the back and glutes. Anterior muscles, which tend to be overused and tight like the chest or quadriceps, need stretching movements to increase mobility. This warm-up strategy helps correct common imbalances to create a healthy posture and a stronger base for movement—the keys to back injury prevention.” Browne also shared a good strategy for preventing muscles injury or strain throughout the work day. “Muscles need a break, even those of conditioned athletes. Without breaks, muscles will begin to break down creating imbalances and overcompensation of other muscles, increasing the possibility of injury. “Multiple studies across a variety of occupations show taking short breaks (micro-breaks) multiple times throughout the day improves physical performance and focus and decreases the occurrence of soft-tissue injuries. Micro-breaks are short—30 seconds to one minute—and help alleviate static positions or repetitive motions. “The key to micro-breaks is taking them before pain and fatigue set in. If possible,

schedule micro-breaks on the hour. Stand if you’ve been sitting, walk around if you’ve been standing in place, reverse the motion if you’ve been working repetitively. “Even if you can’t schedule micro-breaks, think of areas in your day with natural pauses in the workflow. Use those pauses to perform the activities mentioned above. Even taking a few micro-breaks throughout the day will help.” Take to heart the knowledge or practices gained from your natural workflow. For example, artificial intelligence (AI) is giving researchers at the University of Waterloo new insights to help reduce wear-and-tear injuries and boost the productivity of skilled construction workers. Studies using motion sensors and AI software have revealed expert bricklayers use previously unidentified techniques to limit the loads on their joints, and that’s knowledge that can now be passed on to apprentices in training programs. “The people in skilled trades learn or acquire a kind of physical wisdom that they can’t even articulate,” said Carl Haas, a professor of civil and environmental engineering at Waterloo. The research shows master masons don’t follow the standard ergonomic rules taught to novices. Instead, they develop their own ways of working quickly and safely. Examples include more swinging than lifting of blocks and less bending of their backs. “They’re basically doing the work twice as fast with half the effort—and they’re doing it with higher quality,” said Haas. However you discover the right warmup exercise, ergonomic functions or micro-break schedule for your job, notice that the emphasis is on working safely. – BY ASPHALTPRO STAFF Browne cited these sources for more information: http://www.emeraldinsight.com/doi/abs/10.1108/ S1479-3555%282009%290000007005 http://journals.lww.com/annalsofsurgery/ Abstract/2017/02000/Intraoperative__Micro_ Breaks__With_Targeted.17.aspx http://www.workpace.com/assets/Uploads/WhitePapers/Wellnomics-white-paper-The-benefitsof-breaks-and-micropauses-a-survey-of-theliterature.pdf

Alaska Uses Continuous, Full Coverage Testing to Detect Quality The Alaska Department of Transportation & Public Facilities is on the front line when it comes to promoting new technologies that give them continuous, full coverage asphalt pavement density testing for road paving projects. Continuous testing uses multiple inputs to look for failure zones and has a high probability of detecting defects before they lead to premature failures. The system Alaska has opted for combines intelligent compaction (IC), a paver-mounted infrared (IR) thermal profiler/scanner, and ground-penetrating radar (GPR) rolling density meter. Now, Alaska DOT is moving towards a system that will tie project acceptance to data from this system. They plan to offer bonuses for increasing the asphalt compaction averages, and require remediation for compaction below the standards.

NEW PAVEMENT SAMPLING PARADIGM PROMOTES QUALITY

To date, state departments of transportation base quality measurement testing for road paving projects on random sampling of materials. Contractors and producers will recognize the method of one asphalt lot equaling 5,000 tons; that is divided into 10 sub lots of 500 tons each. Quality assurance (QA) personnel use a random number generator to select where each sub lot would be sampled while placing the mix on the grade to check for binder and the gradation of the aggregate. They then randomly select a separate location to take a core in the mat and at any longitudinal joints between two lanes. QA personnel then use statistical methods on the samples to generate information on the theoretical distribution of road paving material properties, and to calculate the average density of material placed. This method does not sit well with Rich Giessel, Alaska Department of Transportation & Public Facilities Statewide Quality Assurance Engineer. He believes this method is not suitable for heterogeneous materials and will not find defects on paving projects.

12 // March/april 2018

Giessel believes the method is based on two false premises. The first is the assumption that soils and other road construction materials will fall on a “Gaussian” distribution (a normal curve). The second assumption is that we should care most about the average density values one gets from random testing. This is just not so, says Giessel: “Random sampling is a really good way to get the average, but when you are doing one test that represents one square foot every 500 tons there are thousands or hundreds of thousands of square feet we have not even looked at. Also, the average spot is never what gives us a problem or a failure on the road—it is the weak spots. Random testing never finds your low spots and your weak spots so there is little to no probability of locating pot-hole size defects.” Giessel has been challenging the status quo in recent years and became a firm believer in replacing the random sampling/statistical approach with continuous full coverage testing methods. The system he favors uses three components: intelligent compaction (IC), a paver-mounted infrared (IR) thermal profiler/scanner, and ground-penetrating radar (GPR) rolling density meter. Readers are familiar with IC. Next is an IR thermal profiler mounted on the paver, which provides a continual map of the temperature of the asphalt as it is laid down right behind the paver. The thermal IR scanner provides geo-located data and a complete map of asphalt mat surface temperature that is viewable in real time, and calculates the degree of thermal segregation every 150-feet, providing a permanent temperature record. The last element in the system is the ground-penetrating radar (GPR) asphalt density meter, which evaluates void content. It rolls along and takes a measurement every square foot of the pavement after compaction. Instead of 50 to 100 random tests, the GPR method provides 2.5 million tests—one on every square foot. This is designed to enable QA personnel to find any defects. Since

Here the PaveScan assesses a longitudinal joint during night paving. the method provides geo-located data, they can go back and fix issues before they lead to premature failures. The ability to measure voids is another benefit, and is the sort of research Giessel has been following in part of the Federal Highway Administration’s Strategic Highway Research Program 2 (SHRP 2) Renewal Project R06C (Using Both Infrared and High-Speed Ground Penetrating Radar for Uniformity Measurements on New Hot Mix Asphalt (HMA) Layers). As part of SHRP 2, the Texas Transportation Institute (TTI) developed a way of using IR and radio wave technologies to improve the assessment of asphalt mixture and compaction quality. TTI later worked with Geophysical Survey Systems Inc (GSSI) to package the radio wave components into the PaveScan® RDM asphalt density assessment tool, a streamlined and operator-friendly device that provides real time profiling of asphalt mixture uniformity. After this first phase, Maine Department of Transportation (DOT), Minnesota DOT and Nebraska DOT continued the research under the federally

funded SHRP 2 project. Alaska DOT participated in two demonstration projects with technology company MOBA Corporation, first with the PAVE-IR Bar and more recently using the PAVE-IR Scanner, a paver-mounted thermal profiler.

ALASKA TRIES IT OUT

Alaska DOT conducted demonstrations of the PAVE-IR technology in 2011 and began using IC in 2013. While visiting an infrared showcase, Giessel saw a demonstration of GSSI’s PaveScan RDM. “I got to walk behind it and watch what it was doing and I was pretty excited about the technology and what it could do for us in Alaska,” Giessel said. Alaska roads can be negatively affected by freeze-thaw cycles; the capital city of Juneau is affected most, with about 50 freeze-thaw cycles per year, giving them extremely difficult conditions to maintain. Giessel used all three components together as part of the recently completed Glenn Highway: Hiland Road to Eklutna Pavement

Preservation project, 15 miles of 4-lane expressway, requiring a bit more than 50,000 tons of asphalt. This was a 2-inch mill-andfill project, where contractors milled out an inch and three quarters or two inches and put back two inches of material. Beginning in 2016, Alaska DOT used the IC and PAVE-IR paver-mounted thermal scanner technologies as contractor pay factors as part of project acceptance. The PaveScan RDM asphalt density assessment tool was used as a technology demonstration only. They obtained full coverage data, but did not connect the information to any pay factors. Giessel stated he’s pleased with the results of the project, noting some unexpected findings. One had to do with the PaveScan RDM’s data concerning compaction at the road shoulder. The project called for milling out and leaving a paved shoulder with a rumble strip. QA engineers found that in some cases the asphalt was not stacked high enough above the paved shoulder to get really good compaction. In the past, they had rare-

ly cored near the edge, so had not observed this area of low compaction; the random selection almost never got within a foot of the rumble strip. Now, the PaveScan RDM measures every couple feet across the road, and engineers were picking up on the shoulder compaction issue. Another interesting finding observed during calibration is that PaveScan readings are much closer to the cores than the nuclear gauge, which had always been their standard proxy for cores. The correlation coefficient (R2) for the nuclear gauge is only 0.82 (82 percent accurate), while the R2 with the PaveScan was 0.93 to 0.95 (93 to 95 percent accurate). Another finding is the ability to use PaveScan to “see” defects they have never seen before, for example, density variation across a longitudinal joint. “We had never been able to see what was going on at those longitudinal joints before,” explained Giessel. “Instead of just running parallel down the highway, I turned the PaveScan 90 degrees and went across those joints perpendicularly.

mix it up We could see as much as a 10 percent compaction dip right at the joint between the milled edge and the new hot mix where the hot and cold edges had not melted together well. That was data we had never been able to see before, so it was pretty exciting.”

GET PAID The Alaska DOT wants to move in the direction of continuous, full coverage asphalt pavement density testing for future projects, especially major arterials, highways and main thoroughfares. They recently received a State Transportation Innovation Council (STIC) incentive award from FHWA, and they want to use the funds to implement this technology more fully. “We want to use PaveScan RDM on a project in the near future for actual acceptance of the compaction of the highway,” Giessel said. “Instead of the drilled cores that we are currently using, we would use the drilled cores only to calibrate the machine at the beginning of the

14 // March/april 2018

Alaska DOT is moving towards a system that will tie project acceptance to data from this system. project. Then we would accept the density on the rest of the project based on the GPR readings. That would be a huge step forward for us.” Alaska DOT is looking forward to moving away from using statistical methods to generate a distribution of values because, even if the average value is good, there could still be weak areas that are below paving standards. These are more likely to cause early failures and maintenance costs, as well as additional costs due to the need for repaving earlier than planned. With their new technology, they can locate specific weak areas that are below established standards. For the upcoming STIC project, Alaska DOT proposes paying the contractor based

on the average compaction value, with a bonus up to 5 percent if he gets the average up to 96 percent. However, if compaction is below 92 percent, the contractor will have to remediate it by going back and applying a sand seal with an appropriate sealer/binder on all low mat sections and joints. Giessel anticipates this approach will encourage additional quality control up front. “It will raise everybody’s awareness of quality work. Basically, we will have no potholes left behind with this program.” As the first state proposing to use the new system for acceptance, Alaska has received encouraging support from FHWA. It is good economic sense to do everything right the first time. This technology and implementing this type of specification has the potential to save the state big dollars in annual maintenance. – BY ROB SOMMERFELDT

training

How to Start the Plant on a Chilly Morning For the 10-Year Anniversary of AsphaltPro magazine, we will help asphalt companies teach new workers some back-to-basics techniques for best success in the field, at the plant and in the lab. Even veteran employees will be reminded of best practices with these refreshers throughout the year, but the goal is to help readers who are bringing in new employees who may or may not be well-versed in the industry yet. On-the-job training takes time and energy, and we’re here to help with the Asphalt Paving 101 online training course and these free articles every month. There are a few extra things to consider when starting up your plant in cooler weather. As soon as you arrive at the plant you should check the status of the hot oil heater system. Make sure the liquid asphalt cement (AC) lines, pumps and storage tanks are hot. Your next step should be to gather all plant employees and inform them of the plan for the day—this will include the mix type, projected tons, shipping, bins to run, etc. You should also take care to follow all daily safety practices. Afterwards you will want to drain any water from the compressor. If there is no auto-drain, you will need to start the compressor to do this. Next, visually inspect the area

16 // March/april 2018

of the belt to make sure it is clear. If it is, you will then give the start-up horn warning. Once the start-up warning has been issued, you will start the scale belts and collectors to remove water and to warm up the load cells. Next, you should check the reject gates and silo flop gates to ensure they move from silo to silo completely before beginning production. After these have been inspected you will want to double-check controls readings for any empty silos by opening each gate. You’ll want to use a haul truck or loader bucket positioned beneath each silo in turn to help with this inspection. Your next step will be to start the exhaust fan and burner blowers. If the plant has a slinger you will also need to start that system now. Next, light the burner to preheat the baghouse and to circulate AC through the pumps and lines, and then start the drum. When the baghouse is near the correct temperature, start the drag and any transfer conveyors for silos that will be used. Next, notify plant personnel before beginning production. Set a production target and start, increasing the burner and managing the exhaust fan speed or damper for proper air flow. Also make sure you monitor the baghouse inlet temperatures.

As the aggregate temperatures increase coming out of the drum you will need to allow the AC to inject. When the mix is coated, and temperatures are acceptable, close the reject gate and monitor silo operation. Check that the batchers are working properly and that the motor amp loads are normal. Begin loading trucks when enough mix is in the silo, and be sure you have enough mix to keep the silo cones protected. Congratulations, you have just started up an asphalt plant on a cold morning. – BY LEN NEWTON

Solve Lift Problems During Plant Maintenance

Is your ground man stuck at the top of a nonfunctioning scissor lift? There are safety protocols to get him back to earth and some common maintenance practices to prevent scissor lift failure. This is the time of year when ground personnel, mechanics and other plant workers are busy gearing up for spring start-up. Not all workers are familiar with fall-arrest protection protocol or proper safety procedures for working on lift equipment. In the event a scissor lift (or other lift equipment) has stalled with a worker on the raised platform, there are safety precautions to be aware of. The worker performing plant maintenance from the scissor lift platform should not attempt to disembark while the lift is stuck in the raised position. A member of the ground team will assist him. The point: do not attempt to get off the platform if it is stuck in the raised position.

Ground personnel will first make sure the worker on the platform above is safe, and won’t be harmed by the lowering of the platform. The ground man will also look to make sure there are no wires, no pieces of equipment, no tools or handles of tools, etc., in the scissor pack. For many lifts, the first step will be to turn the key switch to the “base” position, and then pull out (or twist, or press) the red emergency “stop” button. Then the ground man can operate a switch that lowers the platform. In the event the platform doesn’t respond to the lowering switch, he may need to pull the red emergency lowering handle. In most machines, you will hear a hissing noise as the hydraulic oil flows through the system. Notice that this emergency help requires the machine to be positioned/ parked with the ground controls facing away from a wall; the emergency lowering handle should never be blocked by equipment or by the legs of the baghouse, loadout structure, etc. A free downloadable resource from Nationwide Platforms that you may consider offers emergency lowering guidance for a number of different makes and models of lifting equipment. Visit http://bit.ly/2GBwJGz. To keep your scissor lift’s battery in top condition, a number of resources suggested starting up the machine and letting it run and recharge at least once a month, whether you need to reach high places around the plant or not. Additional preventive maintenance includes proper greasing and following the OEM’s recommended best practices to the letter. – BY SANDY LENDER

This past June, Sanders Brothers added another plant, a Gencor 400 XL Ultradrum with Advanced RAP Entry, in Moncks Corner. 22 // March/april 2018

Sanders Brothers Stretches South Carolina Footprint It all started with a single truck more than 50 years ago. Sanders Brothers Construction Company, Charleston, South Carolina, got its start in the mid-60s when Jimmy and Elliot Sanders started hauling with their single axle dump truck. Then, in the early ’70s, the brothers acquired their first asphalt plant in North Charleston and acquired their second, in Summerville, in 1980. In 1995, the company purchased two 300-ton-per-hour CMI triple drum plants to replace the original plants. This past June, the company added another plant, a Gencor 400 XL Ultradrum with Advanced RAP Entry, in Moncks Corner. Today, the company employs close to 325 employees at its asphalt plants and on its paving crews, as well as performing underground utilities, soil stabilization and reclamation, concrete curb and gutter, grading, hauling, recycling, and vacuum truck and camera services. “We’re always looking for new opportunities to give our employees the opportunity to advance themselves,” Davis said. “We train them, but we also provide opportunities for them to explore new markets, opportunities and areas of business.” For example, a few years ago, the company’s underground utilities superintendent had an idea to get into the vacuum truck and camera systems business. “We ran with it and he built that up to run seven vac trucks and four camera systems in three years,” Davis said. Despite the wide range of services they perform today, Sanders Brothers stays true to its roots in asphalt production and paving. “Typically 50 percent of our company is asphalt focused, and the other 50 percent on site work,” said Sanders’ VP of Asphalt Operations Chris Davis. Within the asphalt portion of Sanders’ business, 75 percent of its operations are in asphalt placement and 25 percent, production. About 90 percent of the asphalt Sanders produces is used by its own crews, on projects ranging from small parking lots and large warehouses to county and DOT work. “Wherever the work is, we’re willing to give it a shot.” Davis started working at the company in 1998 in the quality control department and has been the company’s VP of Asphalt Operations for nearly a decade. “We’ve experienced significant growth and with that comes a lot of challenges,” Davis said, including their new plant, a new safety program, and overcoming new (and old) challenges.

NEW PLANT, NEW OPPORTUNITIES

Sanders’ new plant has been five years in the making. The company first purchased the property in 2012, when they saw an opportunity to streamline logistics. The five-year lead time gave the company more than enough time to find and train new employees. “We were overstaffed for a bit, but we were always looking at the big picture, knowing we’d need them,” Davis said.

“This was a green field site that provided us the opportunity to open a plant with the ability to receive our aggregates by rail, through coordination with our supplier Vulcan Materials,” Davis said. Due to the makeup of the landscape around Sanders, the closest granite quarry is 100 miles away. “One of our plants for the last 15 years has been receiving stone out of Nova Scotia, Canada.” After deciding to establish a new plant, it was time to choose what type of plant to buy. “We did a lot of market research and met with a number of different companies and narrowed it down to Gencor,” Davis said. “They offered us a number of innovative ideas that we thought would be beneficial in our market.” “The new plant has been able to gear up and run at 400 tons per hour, or slow down to 200 tons per hour as we grow with this market,” Davis said. “It wasn’t purchased just for today’s capabilities, but also for the capabilities that it will present us in the future.” Sanders Brothers recently received NAPA’s Diamond Achievement Award for all three of its plants. “We’d done it back in the early 2000s and found it to be a great practice,” Davis said. “When we got our new plant, it was a great checklist of best practices to go through for all of our locations.” The new plant also offered Sanders the ability to run increased RAP percentages over their existing plants, with its Advanced RAP Entry (A.R.E.) system. The A.R.E. system allows Sanders to produce mix with up to 50 percent RAP. Whereas most asphalt plants incorporate the RAP after the other elements have been heated up, the A.R.E. system enters under the flame of the burner prior to the dust, allowing for a longer retention time for the drying of the RAP. A larger drum diameter—9 feet, 9 inches compared to 9 feet for Sanders’ other plants’ drums—reduces air velocity and dust carry-out. Dust is sent to the baghouse, with the fines being returned to the mix. Essentially, the larger space reduces the volume of air moving through it, whereas a smaller space would increase that volume, Davis said. “If you can imagine the same volume of water running through a garden hose versus a fire hose, the water will travel at a faster velocity through a garden hose due to the smaller space,” he added. The Gencor plant is also equipped with dual RAP entry that can be used either for fractionated RAP or shingles—something the company has not started doing yet, but expects to move to in the future. Davis said Sanders makes just about any mix, but that the current mix of choice in South Carolina is Surface Type B with ¾-inch minus surface course, with about 50 percent coarse aggregates. “One thing we’ve been doing is Charleston County has been very prominent in promoting warm mix and has been bidding quite a few warm mix projects,” Davis said, estimating that about 50 percent of the county’s projects for the past two to three years have been warm mix

Within the asphalt portion of Sanders’ business, 75 percent of its operations are in asphalt placement and 25 percent, production. projects. On those projects, the county allows contractors to blend Evotherm on-site at the plant. “So all of our plants are set up with a pump injection system from Ingevity and we’re running warm mix when we can.” “The Ingevity home office is here in Charleston and they’ve done a great job promoting their product with support from local contractors who recognize the benefits of warm mix,” Davis said. However, simultaneously, South Carolina’s DOT does not recognize plant-blended warm mix—only terminally blended warm mix.

SANDERS’ SAFETY PROGRAM

“We’ve always encompassed safety wholeheartedly, but it’s definitely taken on a new meaning,” Davis said, with Sanders’ Brothers’ recent safety initiatives. The Critical Six, or Fatality Prevention, Program at Sanders Brothers was established in 2012 by VP of Safety and Support Services Al Trevino. When he first began working at Sanders, he looked into what events and tasks were causing the most fatalities throughout the construction industry. “It seemed like every fatality I could find would be put in these six buckets: falls, work zone safety, heavy equipment, lockout tagout, trenching and excavation,” Trevino said. “If we could prevent these six, our risks of fatality would be significantly reduced.”

24 // March/april 2018

The Critical Six, or Fatality Prevention, Program at Sanders Brothers was established in 2012 by VP of Safety and Support Services Al Trevino after he identified that nearly every fatality he could find in the industry fell into one of six categories: falls, work zone safety, heavy equipment, lockout tagout, trenching and excavation Since establishing the program, Trevino said Sanders has experienced fewer injuries and incidents. “We’re seeing the benefit both to the employees and monetarily,” Trevino said. “We’ve seen it reflected in our worker’s compensation cases, where we’re seeing very few [claims] compared to what we had before.” In 2017 alone, Trevino estimates that he and Sanders’ safety manager had conducted more than 4,000 hours of training. “Greg Sanders, president of Sanders Brothers Construction, knows safety isn’t just a priority, it’s a core value,” Trevino said. “Priorities change all the time. Core values don’t.” As part of the Critical Six Program, everyone employed by Sanders Brothers has to go through a general awareness training on all six risks.

Today, Sanders Brothers operates three asphalt plants, in North Charleston, Summerville and Moncks Corner. “That’s a 30,000-foot-view of what lockout tagout is or proper fall protection,” Trevino said, “and then if they’re going to be working in an area where they’ll be exposed to one or more of the six risks, they’ll get extensive training in that program.” Beyond the general training, each of the six risks requires another five to seven hours of in-depth, classroom-based training with Trevino. For example, if someone will be working with grading, they will take the work zone safety, heavy equipment, lockout tagout and falls training programs. “For lockout tagout, the classroom training would cover the fundamentals of why we follow it, how to do it, and how to recognize those hazards and determine risk,” Trevino said. Sanders has a risk assessment scale of one to four, with four being catastrophic, that it teaches its employees to use to determine the risk of any given task. If a hazard is deemed high-risk, the company will bring in more people to help, hold more pre-job briefings and have a meeting immediately before the job takes place to go over who is performing what, how they will do it, and to pass out PPE.

Producer profile The classroom training also covers federal and state regulations, as well as Sanders’ own site-specific programs that Trevino has written based on federal regulations. All training is led by Trevino, face-to-face, with the occasional YouTube video. “I train everyone myself, so I know if someone is falling behind,” Trevino said. “And if they are, I’ll slow down, use more examples and call on them to walk through what they’d do in a situation.” Although the classroom can sit up to 20 people comfortably, Trevino aims for groups of eight to 10 people for initial training and groups of 20 for the refresher courses. However, he doesn’t wait to have a group of any particular size before training new employees. “I’ve done training for just one person at a time before,” he said. “Because no one goes out in the field without that training.” There’s also a test at the end to make sure everyone has thoroughly absorbed and internalized the lessons learned. “If not, they’ll be spending more time in the classroom with me,” Trevino said. After the classroom training, the safety program continues in the field with practical training. “We pretty much train on those six on a daily basis,” Trevino said, adding that the company also re-trains existing employees every three or four years. If an employee gets injured in the field or is involved in an incident, Trevino calls them back to the classroom for more training. “If there’s an incident, or if I see someone doing something not quite the way we trained them, I’ll ask why they’re doing it that way,” Trevino said. “And

I’d rather have someone be angry at me than to have someone get injured or die in the field.” – BY SARAH REDOHL

meet the state exec

Meet the State Exec: APAO’s John Hickey The Asphalt Pavement Association of Oregon was first formed in 1969. Now, the Salem, Oregon-based association boasts 45 producer and contractor members that represent 97 percent of the tons produced in Oregon. APAO holds its annual meeting in December and the Oregon Asphalt Pavement Conference in February or March each year. “We bring in experts in asphalt pavement from across the country to present on developments in asphalt pavement technology, equipment, and workmanship,” said APAO’s Executive Director John Hickey. “Our conference provides national expert access to local agencies, companies and individuals who do not have the budgets to attend national conferences.” “Because we frequently partner with the Oregon Department of Transportation, the conference also helps us coordinate with ODOT and ensure that we have similar goals for the advancement of asphalt pavement in Oregon,” Hickey added. Leading up to Oregon’s annual conference March 13 and 14, AsphaltPro spent time getting to know Hickey and how APAO promotes the asphalt industry in the state of Oregon.

What are the top ways you have increased membership in the association? Membership recruitment and retention is through communicating benefits through our newsletter, social media and face-to-face meetings. Our goals include keeping members informed of our efforts to improve and promote asphalt pavement, and we try to have fun networking opportunities where associate and affiliate members can interact with producer and contractor members. What is your favorite method for recruiting new asphalt professionals to the industry? In-person presentations to groups of high school or college students of no more than about 30. I enjoy showing

His most rewarding experience since joining APAO has been being recognized less as a lawyer and more as a knowledgeable industry representative. up with three or four member representatives and each of us telling how we ended up in the industry. Because our backgrounds are so diverse, the kids leave understanding that the key to advancement in the asphalt pavement industry is desire and not formal education. I also enjoy seeing their eyes widen when we pour water through a porous pavement puck. What other activities does the state association hold for members as fundraising events? In 2008, APAO members formed the Asphalt Pavement Association of Oregon Education Foundation (APAOEF). The APAOEF is a separate entity, and is a 501(c)(3) charitable organization. Each year, the APAOEF awards scholarships to students interested in asphalt pavement technology. The primary fund-

raising activities are a golf tournament, family bingo night, guided fishing trip and wine sales. For wine sales, we occasionally bottle a barrel of wine from an Oregon winery and sell it at a small markup. The golf tournament is by far the best fundraiser. Does your office hold educational seminars or webinars for members separate from the annual meeting and convention throughout the year? Yes, we offer many certification classes and educational opportunities. APAO’s strategic plan includes promoting the use of asphalt pavement through continuous quality improvement through member and customer education and training. About how many member asphalt projects do you visit per year? What

about member asphalt plant tours? Member asphalt open house events? State agency or DOT meetings? I usually visit more than 20 asphalt projects each year and go on only about one plant tour. We typically do not have open house events that are separate from plant tours. I also go to more than 10 agency meetings each year.

On a scale of 1 to 5 (1 being none at all; 5 being very much), how involved are your asphalt members in transportation issues such as funding and infrastructure improvements? APAO members range from a 1 to a 5. Some members simply cannot put up with politicians not doing what they know is right for political

reasons, and other members understand that nothing will ever get done unless we put sustained pressure on our elected officials. How did you join the asphalt industry? And how long have you been in the industry? I was a practicing lawyer in a law firm when the possibility of joining

On a scale of 1 to 5 (1 being none at all; 5 being very much), how much of a threat to your membersâ&#x20AC;&#x2122; marketshare/ livelihood is the concrete industry in your state? 2.5. This past year ODOT built a round-a-bout out of concrete on a major access route for Central Oregon. Although life cycle cost analyses showed that asphalt pavement would have been cheaper, the analyses were not determinative because the round-a-bout was considered a safety feature, and safety features are not subject to the same budgetary requirements as other infrastructure investments. It appeared that the final decision was made by the local engineer who simply favored concrete. On a scale of 1 to 5 (1 being none at all; 5 being very much), how much difficulty are your members having in finding qualified workers for their asphalt paving or production crews? Beyond a 5. We attend career fairs and present on the opportunities in the industry at as many high schools as is reasonably possible. We are working on developing short video clips and an asphalt careers webpage and developing relationships with career services offices at local community colleges. On a scale of 1 to 5 (1 being none at all; 5 being very much), how involved are your state elected officials in transportation issues such as funding and infrastructure improvements? At the federal level, Oregonâ&#x20AC;&#x2122;s elected officials are leaders in promoting increased funding for transportation infrastructure. At the state level, the Oregon Legislature just passed a relatively large infrastructure bill that will help reduce the infrastructure investment shortfall. Although the Oregon Legislature showed great leadership, we now need to make sure they realize that the problem is not solved, they simply made it a little less of a problem.

Out of all of his responsibilities, Hickey believes the most important part of his job is to be a unifying voice for the asphalt industry in Oregon.

the asphalt industry arose. I could either continue to surround myself with lawyers, or join the asphalt industry and surround myself with contractors. No one in their right mind would pick the lawyers. [How long Iâ&#x20AC;&#x2122;ve been in the asphalt industry] is complicated. As a research assistant at the University of Massachusetts Dartmouth in the late 1990s, I worked with Dr. Walaa Mogawer on the implementation of Superpave in Massachusetts. I took a break from asphalt pavement for a few years until working with APAO as an attorney in 2007 or 2008. I represented many asphalt pavement contractors as a construction lawyer for about 10 years before shifting back into the technical aspects of asphalt pavement in late 2014. Do you have a degree related to the industry? I have Bachelor of Science in Civil and Environmental Engineering from the University of Massachusetts Dartmouth, and a Juris Doctorate from the University of Oregon. When I was attending UMass and working as a research assistant for Dr. Walaa Mogawer, I remember him promoting asphalt pavement materials as a career path because the majority of our transportation infrastructure system is asphalt pavement. All of us students took the roads for granted and wanted to design bridges or high-rise buildings. To date, I have never designed a bridge or a high-rise, and I work with asphalt pavement every day. What do you see as the most important part of your job as an executive director of a SAPA? Being a unifying voice for the industry in Oregon. What is the most challenging part of your job, and why do you think itâ&#x20AC;&#x2122;s a challenge in your state? There is no shortage of challenges for any SAPA: doing what is right for the industry rather than any particular member; developing relationships with the DOT and local agencies despite disagreements; advocating for adequate infrastructure funding in the face of tightening budgets; planning meetings, events, and conferences; recruiting members; communicating intangible member benefits; motivating and facilitating board and member participation; managing staff; addressing regulatory changes; recruiting the future workforce; setting

the direction for the improvement of asphalt pavement technology in the state; and others. The most challenging part of my job simply is the biggest emergency on any given day. What do you find most enjoyable about your job as an executive director of a SAPA? There is no question that the most enjoyable part of my job is interacting with member contractors. APAO’s members are full of quality people who value family, hard work, friendships, and fun. From a people standpoint, there is no better industry.

Hickey visits more than 20 asphalt projects each year.

What has been the most rewarding experience for you during your time as the executive director? Being recognized less as a lawyer, a profession with a reputation of having members willing to say just about anything for money, and more as a knowledgeable industry representative who will represent the industry’s best interests over any one member. – BY SARAH REDOHL

International snapshot

International Bucket Mining An area that has seen benefits of the ALLU Transformer range is surface mining operations. The Transformer is designed to fit an excavator or loading shovel, which works for large scale surface mining operations where transportability is a requirement of material handling equipment. With many units now working throughout Brazil, one such application has seen the ALLU Transformer M-Series in use at a nickel mine, screening chalcedony directly in the mine to upgrade the nickel concentration on the processed material. This model was chosen due to its high mobility and functionality in screening the material in situ. The company screens the material on site rather than loading it onto trucks, transporting it to a stationary screening plant, and so on. The ALLU Transformer M-Series has proved to be ideal for soft rock surface mining applications in Brazil, handling materials within its range in “one step.” It has been designed to fit excavators and wheel loaders of up to 154.4 U.S. tons (160 tonnes).

P&S Warms Up Quality on I-95 BY SANDY LENDER

34 // March/april 2018

W Chris McGuire is the regular wheel loader operator who feeds the reclaimed asphalt pavement (RAP) into the fractionating plant from KPI-JCI. The plant has two RAP bins calibrated for coarse RAP and fine RAP.

When the 320-degree material gets placed at night, ambient temperature can start to play with your workability. For P&S Paving, Daytona Beach, Florida, knocking the production temperature down to the 270-degree range can be the answer. They include Evotherm warm-mix asphalt (WMA) additive from Ingevity of North Charleston, South Carolina, in all their mixes, and the practice has come in handy during the 14mile Interstate 95 (I-95) project in Florida, specifically. Director of Quality Control Tim Carter explained, “Everything at P&S Paving has Evotherm in it. I’m a big proponent of M-1.” The team’s experience not only with the use of additives, but also with quality production and paving practices, has brought them success implementing in-house quality control/quality assurance (QC/QA) and getting excellent numbers on the I-95 project.

SUBCONTRACT SUCCESS

The Florida Department of Transportation (FDOT) reported that general contractor Archer Western Construction, Chicago, began the design-build project on I-95 in 2014. The project includes widening and realigning a section of the interstate referred to as International Speedway Boulevard [U.S. 92] as well as systems interchange reconstruction. The asphalt paving falls under the jurisdiction of subcontractor P&S Paving, including sections P&S subs out, to the tune of 140,000 total tons on the project, plus over 30,000 tons in temporary lanes. One aspect of the ongoing project is planning for the future, and that included raising Bellevue Bridge to accommodate a future train right-of-way. The I-95 Project Team at FDOT, under the direction of FDOT Project Manager Christopher Briggs, P.E., shared: “The Bellevue bridge height increased 5 to 7 feet higher than the previous bridge. The height depends on where it is measured from. Now that collector distributor roads are being added, the bridge also lengthens as well. The I-95 bridge over U.S. 92 where the potential alignment for the future rail might go was raised 5 feet. The minimum height requirement from the roadway for the future rail line is 23.5 feet.” Carter explained that while paving up to the raised bridge, the paving crew encountered and overcame the challenge of nighttime temperature fluctuations. The FC-5 mixture specified for the project is an

open-graded friction course, to shed water, with a PG82-22, to resist rutting. “PG82-22 mixes are also one of the most sensitive designs in terms of temperature, so the window of opportunity to properly seat the stone is very limited,” Carter explained. “When Evotherm is added to the mix, it provides additional workability time to address issues as they arise, such as the removal of any deleterious materials on the mat.” For the crew placing the 1.5-inch surface course on the ramps to the newly raised Bellevue Bridge, nighttime temperatures and dew provided the workability challenge. Carter explained the production temperature of the mix was hitting 315 to 320 degrees F. If the ambient temperature is in the 60s, FDOT allows contractors to keep paving, but when ambient temps drop, FDOT wants contractors to stop in the name of quality. Carter’s team at the plant took the production temperature down to the 270 degree range, which is a benefit of using a warm-mix asphalt additive such as Evotherm. Sources spoke to the addition of Evotherm for in-field performance. In this case, the warm-mix additive is functioning as a compactive aid and increasing the time for compaction. Even with good materials, ambient temperatures in the winter of 2017 and early 2018, after busy tropical seasons, gave the team pause. “Fortunately this winter’s cold weather has impacted the overall progress of the project only in a small way,” the project team reported. “The project is so large that we are able to work on various activities not dependent on warmer climates. With good planning, hard work and a little bit of luck, the completion of the southern portion of the project was achieved prior to the winter. The open graded friction course, which requires higher temperature for its installation was laid prior to November. Now the focus is on completion of limerock base and structural asphalt on the north portion of the project. The anticipated project completion has shifted to the fall of 2018 due to the compounded effect of rain and added work.” The good news is Archer Western, P&S Paving and Halifax have kept communication and quality top of mind throughout the rainy or cold seasons. “Despite having had two consecutive years with hurricane impacts to the project,

The Florida Department of Transportation Project Team reported: “As part of the Design Build selection process, the firm offered to use a PG8222 binder in the top lift of structural asphalt and FC-5 on the I-95 travel lanes. This binder selection will help toward having a longer pavement life.” Photo courtesy FDOT Public Involvement. the progress has been great,” the project team reported. “The 9-mile section of I-95 from SR44 to just south of I-4 has been reconstructed to accommodate a third lane in each direction and has been opened to the traveling public since October of last year. This would not have been possible to achieve so soon without the excellent communication and coordination among Archer Western, P&S Paving and Halifax Paving. Archer Western completed four key bridges and drainage along the corridor, while P&S Paving and Halifax Paving worked on completing the roadway portion.” Carter confirmed P&S Paving’s crew performed the paving on the 10.5 miles from S.R. 44 to south of I-4 that were completed by November 2017. “P&S is the primary sub-contractor responsible for all of the paving but it should be noted that we use an

additional contracting firm to provide the paving for portions of the project as well but they do fall under our umbrella of paving responsibility for the project.” Carter’s QC team places a priority on quality from start to finish. That means mix design and testing in the lab is serious business. Lab QC Manager Edward Madigan and Roadway QC Manager Carleton Dobbins came to P&S Paving with Carter about three years ago when the company brought testing in-house. Carter shared how their inhouse team attitude shapes day-to-day jobs. “Carleton will make sure the three roadway QC techs have the training and tools they need, but he doesn’t micro-manage them. Ed manages the three lab QC techs. Those guys really make things happen in the lab and on the roadway in real time. They make decisions in the moment. Their teams are all responsible for keeping quality fine-tuned.” Carter shared that the QC team encourages innovation and ideas, but only adopts a new idea if it’s something they can implement across the board. “Consistency is a mantra,” he said. “If it was a good idea at

Gravity—it’s not just a good idea, it’s the law. P&S Paving Company puts gravity to work even when receiving liquid material. Notice this driver has the front end of the tanker on the 18-inch high tanker offloading island so the material flows downhill, making the pump’s job a little easier. another company, we might adopt it here, but we’re going to do it the same way and make it right.” For the I-95 project in particular, getting quality “in a hurry,” is one objective.

Carter explained that the paving crew often has short paving sections on the I-95 project, and may have more than 30 days before the next section is to be paved. With a 30-day time limit on the percent-with-

in-limits (PWL) program, that means pay factors are based on short paving sections. “It’s important that we stay consistent in those short windows,” Carter said. “The pay factors on the project were gradation, texture, spread rate and liquid binder content. With spread rate restrictions in particular, there is a high probability of texture issues because you’re laying the asphalt so thinly. So it’s important that the stone coats well and stays put quickly. This is where Evotherm really helps. We just don’t see any tenderness, pushing or shoving of the asphalt.” The spread rate was specified at 83 pounds and the liquid binder content was 6 percent. P&S Paving’s commitment to quality shows on the I-95 project’s numbers, as reported by the FDOT Project Team: “During projects, the department has measures in place to award or deduct, from the quality of the asphalt left on the project,” the project team reported. “We want the best quality asphalt that we can get. So we have a scale that measures asphalt called the CPF (composite pay factor). The CPF goes from 0.95 to 1.05 with 1.0 being the middle point. As the contractor makes and places the as-

phalt, they get a CPF on that asphalt; now anything below 0.99 to 0.95 is a deduction (still acceptable asphalt) and 1.0 is no deduction or award, and anything above 1.01 to 1.05 is an award for having asphalt above the middle point. P&S has pretty much

been above the 1.0 CPF for the project, which shows their dedication and ability to perform. The project has performed and produced good, quality work and asphalt that is a true reflection of the project team wanting and trying to perform higher than

Design with Asphalt in Mind The FDOT Project Team spoke to the efficiency of the team and process on I-95. “Speed of delivery of this project is impressive. This I-95 project was bid using a Design Build delivery method, and as a result of it a firm with design and construction capabilities was hired to reconstruction 14 miles of I-95 from SR 44 to just north of US 92. The bid includes every aspect necessary to complete this project with the exception of purchasing the necessary Right of Way. In Design Build contracting the firm makes the design decisions that fit their strategy and proceeds with early construction basically compressing the schedule. As part of the Design Build selection process, the firm offered to use a PG82-22 binder in the top lift of structural asphalt and FC-5 on the I-95 travel lanes. This binder selection will help toward having a longer pavement life. During the reconstruction process, a 10-foot paved shoulder was maintained to allow breakdown vehicles to pull off the travel lanes….Half of the paved shoulder’s width was temporary and RAP material was used for its base cutting down on cost. The temporary paved shoulder definitely had a positive impact on motorist’s safety and their ease of travel. Design Build is highly recommended for larger projects that need to be completed in the shortest time possible.”

The team raised the Bellevue Bridge 5 to 7 feet higher than the previous bridge to accommodate a future train right-of-way.

P&S Paving’s crew performed the paving on the 10.5 miles from S.R. 44 to south of I-4 that were completed by November 2017.

McGuire also feeds RAP to a fractionating plant from KPI-JCI to get sized material for high-percentage RAP mixes. At this time, the plant has two RAP bins—one is calibrated for coarse material, one for fine. The plant is rated to run up to 65 percent RAP, according to Carter. Even incoming liquid material is offloaded with gravity’s help. When delivery trucks arrive, the drivers pull onto an 18-inch tall “speed hump” so the tanker is resting on an

incline. The tanker offloading island makes the pump’s job a little easier when filling up a tank at the farm. Carter said the Heatec calibration tank at the tank farm lets them calibrate any liquid at any time. “Blending Evotherm at the terminal prior to shipment also makes it easy to use and ensures that every drop of liquid receives the proper dosage for maximum consistency. We get paid for consistency, so I do everything I can to get paid the most.”

Charlie McCrimmon, at left, and Tim Carter discussed their satisfaction with the ease of use of the Astec controls at the plant. McCrimmon has worked as a plant operator for over three and a half of the 10 years he’s been with the company. He started out on the paving crew, so he knows what the team in the field needs from the plant.

The project’s mindset is to doing it right the first time and produce the highest quality product that we can.” P&S Paving’s management took the time to slope and pave the area beneath the stockpiles to facilitate moisture runoff. The water is collected in a ditch that feeds into a pond onsite where the conservationist in me was delighted to watch a blue heron hang out for sunset. The asphalt facility planning team has done more than provide a peaceful setting for the regional wildlife. They’ve made it possible for the wheel loader operator, Chris McGuire, to get clean, dry material fed to the plant. From a point at the base of the cold feed bins all the way down through the stockpile to the back curb, there is six feet of fall. At the back curb, runoff is collected in the ditch and redirected out to the pond area.

MAKING PAVEMENT PERFORMANCE MEASURES MATTER

BY SARAH REDOHL

155,902. That’s how many total lane miles of roadway need resurfacing or reconstruction in the United States at this time. The Moving Ahead for Progress in the 21st Century Act (MAP-21) and the Fixing America’s Surface Transportation (FAST) Act aim to resolve this issue. And last year, the final rule was published in the Federal Register as the third in a series of rules that together established a set of performance measures for state departments of transportation (DOTs) and metropolitan planning organizations (MPOs). The final rule implements performance management requirements by requiring state DOTs to measure and report on transportation resources’ condition using the same metrics and measurements nationwide, as well as set targets and measure progress towards those targets. Under the final rule, state DOTs are to set statewide 2- and 4-year targets for the non-Interstate National Highway System (NHS) and 4-year targets for the Interstate. The first 4-year performance period began in January 2018, and each state DOT, with help from MPOs, must establish its targets by this May. “States will set targets based on their expectations of pavement conditions at the end of the performance period given the existing conditions, expected deterioration and investments in the highway system,” said FHWA representatives. “Additionally, states can adjust their 4-year targets midway through the performance period.” January 2018 also marked the start of DOTs collecting data for Interstate pavements required by the final rule, including International Roughness Index (IRI), rutting, cracking percentage, faulting, and inventory, with the baseline report due Oct. 1 of this year. Then, they must submit data annually for Interstates’ conditions on or before April 15. States also must submit non-Interstate roadway conditions every two years on or before June 15. “States have been collecting the data they need to do target setting as part of their pavement management system,” said FHWA representatives. “Reporting that data to Highway Performance Monitoring System on a full extent basis is new in the required regulation.” FHWA will use that data to determine annually if each state is in compliance with this minimum condition requirement, which is an absolute minimum level of no more than 5 percent poor Interstate pavements, and 10 percent for Alaska. If FHWA determines the state DOT’s Interstate pavement condition falls below the minimum level for the most recent year, the state DOT must obligate a portion of National Highway Performance Program and transfer a portion of Surface Transportation Program funds to address Interstate pavement condition. “The major impact of the transfer and obligation requirements will be less flexibility on the use of federal funding,” said FHWA representatives, “but many of the states are already investing more than the required amount in the Interstate system.” For example, California, Florida and Missouri DOTs don’t expect major changes as a result of the final rule. “The condition of the department’s pavements and bridges ranks in the top of the nation,” said Florida DOT Communications Director Dick Kane. “The department’s existing asset management practices result in pavements and bridges which exceed established department

42 // March/april 2018

performance requirements founded on Florida Statute and targets for the new FHWA Pavement and Bridge Performance Measures.” As such, Kane doesn’t expect much, if any, impact to project level reporting for maintenance, rehabilitation or new construction—a sentiment seconded by Missouri’s DOT. “The final rule required us to report on additional pavement conditions metrics,” said Ben Reeser in MoDOT’s transportation planning department. Historically, MoDOT collected smoothness, or IRI, data for its condition rankings, though it will now also collect rutting, cracking and faulting data to measure pavement condition under the final rule. Despite those measurement changes, Reeser said MoDOT also doesn’t anticipate significant changes in the amount of pavement maintenance or construction as a result of the final rule. “MoDOT has been measuring performance for many areas, including pavement and bridge conditions, for more than a decade through our Tracker system,” Reeser said. “We will continue to focus on preventive maintenance strategies that have been in place to keep infrastructure in good condition.” Although California expects to bid more paving projects in the coming years, it is not as a result of the final rule. “Caltrans already set pavement and bridge performance targets with its Transportation Asset Management Plan, which the California Transportation Commission adopted in 2016,” said Caltrans Public Information Officer Erin Gallup von Tersch. “While a different requirement (state vs. federal), SB 1 states that by the end of 2027, not less than 98 percent of the statewide system must be in good or fair condition.” To meet that target, Caltrans is committed to fixing more than 17,000 lane miles of pavement and expedited 50 additional pavement projects worth $243 million going into construction as early as this spring. But this may not be the case for every state. According to ARTBA Chief Economist Alison Premo Black, the following states currently have more than 5 percent of Interstate highways rated below the standards: Hawaii, Louisiana, Maryland, Michigan, New Jersey, New York and Washington. “This is based on our analysis of data from FHWA’s highway statistics,” she said, adding that four of those states are at 6 percent, “so they are pretty close.” FHWA said that although the MAP-21 and FAST Act granted states more flexibility to use federal funds, they also required additional planning, asset management and performance management programs to define investments and performance of the system. “In reviewing these programs and participating in the processes, contractors may be able to identify opportunities to help states and MPOs address performance gaps, e.g. identifying innovative solutions to more efficiently and cost-effectively address pavement condition,” FHWA representatives said. FHWA is currently reviewing how to make target information transparent to the public, but feasibly, knowing the state of your State DOT could benefit your bottom line as a paving contractor.

ALABAMA DOT GETS ANOTHER AWARD

During the Dec. 8, 2017, awards luncheon, the Alabama Asphalt Pavement Association (AAPA) presented a 2016 Perpetual Pavement Award to the Alabama Department of Transportation (ALDOT). The award-winning project was a 2.5-mile section of SR-3 (US 31) in Morgan County, between Hartselle and Decatur, Alabama. This is ALDOT’s eighth Perpetual Pavement Award in 12 years. To qualify for this prestigious award, a pavement must be at least 35 years old and never suffered a structural failure. This section of SR-3 has gone more than 20 years without requiring major maintenance. More than 18,000 vehicles each day use this road (4 percent of which is heavy truck traffic), and it has carried almost 3.2 million equivalent single-axle loads (ESALS) through the years. This project demonstrates the characteristics expected from long-life, perpetual pavement design: excellence in design, quality in construction and value to taxpayers.

Mr. Mel Monk, P.E., Executive Director of AAPA, presented the crystal obelisk to Mr. Derrick Wilson, ALDOT North Region Construction Engineer and John Cooper, ALDOT Transportation Director. When asked about the signficance of this award, Cooper replied, “Decades after its construction, this section of SR-3 continues to reliably serve the citizens of Alabama, providing a vital connection between the cities of Decatur and Hartselle. The endurance of the asphalt pavement is a testament to the quality of engineering, construction and component materials. The Alabama Department of Transportation is honored by the selection of SR-3 for a 2016 Perpetual Pavement Award.” “The advantages of these perpetual pavements are significant,” said Amy Miller, P.E., National Director of the Asphalt Pavement Alliance. Life-cycle costs are lower because deep pavement repairs and recosntruction are avoided. User delays are reduced because minor surface rehabilitation requires shorter work windows and can avoid peak traf-

And there are environmental benefits because minimal rehabiliation, combined with recycling any materials that are removed from the pavement surface, reduces the amount of material resources required over the pavement’s life.” – FROM APA

INNOVATION: SMART DAMPING FOR ROADS BY ANNA QUINN

Fielding Staton’s nano-particle-infused technology can be used in the asphalt binder or as an asphalt coating. For Fielding Staton, founder of Newtonoid Technologies LLC, frustration over a cracked windshield evolved into a new Internet of Things (IoT) application that can help gauge roadway health. In 2012, Staton was driving to a jobsite when a rock flew up from the pavement and cracked his windshield. He wondered what he could do to prevent such an occurrence, and that’s when Newtonoid Technologies was born. Staton developed the Absorbud® windshield protection system. It’s a collection of simple energy-dampening devices that attach to the inside surface of a car windshield. When debris hits the windshield, the devices are designed to absorb a portion of the impact to prevent the windshield from breaking. Since developing the Absorbud system, Staton and his team of engineers have been developing increasingly sophisticated damping systems and devices that serve as innovative solutions to common problems experienced across a wide array of industries. One of those industries is asphalt. The basis of Staton’s technology centers around anti-vibration technologies designed to provide stabilization and vibration reduction in systems used in industrial automation, railways, automobiles, medical devices and construction. Recently, the technology has grown to include adhesives and other carriers that include specific “smart” damping mechanisms (or particles) that can be programmed to communicate material information in addition to providing anti-vibration and controlled resonance capabilities. One specific instance includes an adhesive binder for roadways, termed a “damping adhesive.” The damping adhesive consists of an adhesive (or binder) that has a plurality of smart nano-particles dispersed therein. The nano-particles function as sensing and control devices that can be programmed to receive information from the environment and to perform an action in response. Partnering with scientists at a prestigious midwestern university, Staton is working to develop applications for his damping adhesives that include using smart sensors and damping mechanisms to measure amplitudes and frequencies of physical vibrations within roadway systems. Notably, incorporating the damping adhesive into asphalt binder or on asphalt as a coating, can be one step in incorporating IoT into

The damping adhesive can provide information on roadway health and communicate with traffic signals and other systems run by a department of transportation. Information transmitted by the specialized sensors can lead to a wealth of knowledge that can help in planning for road construction and design, as well as measure shock and vibrations within the roadways. In addition, this technology has applications to help road owners and those working in the pavement industry address the frustration and expense involved with mitigating traffic noise and vibration. Staton’s state-of-the-art technological advancement makes it possible for those in the asphalt industry to design or use products that operate more quietly with less vibration and greater efficiency, yielding longer life for the roadways. The impact of these innovative new technologies on the asphalt industry could be far reaching and transformative in today’s IoT world.

FUND TO FIX THE BROKEN PARTS

FROM RAND

Transportation and water infrastructure funding and finance in the United States are not nearly as dire as some believe, but a national consensus on infrastructure priorities, accompanied by targeted spending and selected policy changes, is needed, according to a new RAND Corporation study. While much of the nation’s transportation and water infrastructure is adequately maintained, a 2.5 percent to 3 percent annual spending increase above the total of more than $235 billion now spent annually by local, state, and federal agencies on transportation and water infrastructure largely would eliminate existing maintenance backlogs by 2030, according to researchers. For more transformational change, a national consensus on capital spending priorities is needed to target regional and national-scale opportunities to meet 21st century needs, while accounting for different priorities across regions and between urban and rural areas, according to the study. State and local governments already shoulder most of the burden of building and maintaining infrastructure like roads, highways, bridges, water and sewage treatment, storm water systems, airports and ports. The RAND study says such infrastructure projects need federal support through tax advantaged financing, efficiency improvements in regulatory processes, and research and development. “Spreading federal dollars around to fund short-term, shovel-ready projects without a sense of national purpose or priority will not get the nation where it needs to be,” said Debra Knopman, lead author of the report and a principal researcher at the RAND, a nonprofit research organization. “The federal government should focus on maintaining and modernizing vital federal infrastructure and on targeting nationally significant projects that are beyond the capacity of individual states and cities.” Examples include re-engineering connections among regional highway and rail lines, port-rail-highway junctions, airport modernization, major dam repairs, and infrastructure on military installations, in national parks and other publicly managed recreational areas. Federal assistance can be through direct spending or through the tax code. If it wanted to ensure that state and local governments have reliable and sustained access to capital from a broad class of investors, Congress could preserve the federal tax exemption on interest earned from municipal bonds for at least the next decade, reinstate taxable Build America Bonds, and experiment with other financing alternatives that keep capital flowing to local and state infrastructure investment, including investment through public-private partnerships. RAND researchers also offer other policy options for Congress that could be used to help the federal government—working with state and local governments and the private sector—to renew and modernize the nation’s infrastructure. Among these options, RAND researchers list major investments in the renewal of the nation’s most-critical aging and new infrastructure, incorporating advanced technologies to support newer

48 // March/april 2018

construction methods, more-durable and sustainable materials and sensor technologies that might benefit infrastructure maintenance. In addition, federal capital funding could include requirements to make projects resilient to natural disasters and climate change in order to reduce future spending on disaster assistance. The report Not Everything Is Broken: The Future of U.S. Transportation and Water Infrastructure Funding and Finance is available at www.rand.org. Other authors of the study are Martin Wachs, Benjamin Miller, Scott Davis and Katherine Pfrommer. This project was supported by Lovida H. Coleman Jr. and other RAND donors, income from RAND’s endowment, and RAND’s program of self-initiated research. This research was conducted in the RAND Infrastructure Resilience and Environmental Policy Program, part of RAND Justice, Infrastructure and Environment.

Big Points from RAND Report In the report Not Everything Is Broken: The Future of U.S. Transportation and Water Infrastructure Funding and Finance, authors Debra Knopman, Martin Wachs, Benjamin M. Miller, Scott G. Davis and Katherine Pfrommer, discuss a number of key policies that influence how each level of government invests in new construction and maintenance of infrastructure. One of their key findings, which the general public may take comfort in, is “[t]he data do not support a picture of precipitous decline in national spending on the physical condition of transportation and water infrastructure.” Here is a list of recommendations the authors offer from the report released Dec. 5, 2017: • Preserve the federal tax exemption on interest earned from municipal bonds for at least the next decade. • Reinstate Build America Bonds (BABs) with taxable interest for a ten-year period and experiment with other financing alternatives. • Target longer-term projects likely to produce significant national benefits. • Focus on capital investment, including major investments in renewal of aging infrastructure and new infrastructure incorporating advanced technologies. • Prioritize maintenance of federal assets, such as mission-critical military bases, dams, levees, locks, national parks, and other vital federal infrastructure. • Make resilience to natural disasters and adaptation to rising seas, increasing flood frequency, and other changing climate impacts a condition for spending. • Streamline the regulatory review process among multiple federal agencies. • Consolidate the U.S. Army Corps of Engineers and the U.S. Bureau of Reclamation into an integrated national water resource agency. • Fund competitive grants for research, development, and deployment of new technologies.

WORLD OF ASPHALT/AGG1 2018 BRINGS INDUSTRY INNOVATION, EDUCATION TO HOUSTON

RETAIN WHAT YOU PAY FOR DURING TRAINING

BY SANDY LENDER

At this year’s World of Asphalt/AGG1 conference and expo at the George R. Brown Convention Center in Houston, attendees have three days of courses from which to select education opportunities. Between the WOA’s People, Plants and Paving Conference, and AGG1’s Aggregates Academy alone, there are over 110 seminars and a couple forums/roundtables available. That means you could spend all day each day in classrooms listening to speakers help you learn new concepts or updates to tried-and-true concepts. That, my friends, is a lot of information to take in. Back in November, Mr. T.J. Young of Duval Asphalt spoke at the Asphalt Contractors Association of Florida annual conference, and shared an intriguing concept he learned early in his career about the loads of information and education and industry knowledge we take in. His mentor taught him, “You can learn 80 percent of what you need to know in this business in about two years. It’ll take you another 20 years to get the other 20 percent.” Young referred to this as the 80/20 ratio during his presentation that day, making it clear to the audience that by training our work force to master the first 80 percent—the bulk of the knowledge necessary for quality production and quality paving—we can then drill down on the details that enhance and improve operations. Maybe cramming the 80 percent into your brain is sufficient for you. But I think you attend, and send employees, to events such as ACAF’s conference and WOA/AGG1 to delve into the extra 20 percent. What I think we can take away from Young’s talk in Florida is that our industry has a host of basic best practices that don’t take a long time to learn. We can get the good, solid, top quality testing, production, paving, maintenance and other practices into a new hire’s arsenal in a reasonable amount of time, and then raise expectations from there. It’s not good enough to stagnate at the 80 percent level. You send them to WOA and the like. And you want them to get the most out of the experience. Since season shutdown, companies have flown their star employees to training centers around the country and have brought training consultants to their home offices in the name of improving quality for 2018 and beyond. Monthly sales of the Asphalt Paving 101 online course from AsphaltPro magazine have more than doubled, and OEMs offering training at their facilities report sold-out classes in the first quarter of the year. This means companies care about educating their workforces. How do you ensure the time you spend in the chair translates to better practices in the field? Now, with a course like the one from AsphaltPro, you have the option to watch the videos over and over as often as you need to. But when you get to Houston—or the OEM’s training center—you have a finite number of minutes in front of the instructor. How do you ensure the training you engage in sticks? Let’s turn to the fields of education and healthcare for some tips and tricks to get the most out of the dollars you spend on training your employees. A host of university and college prep sites suggest new students talk about what they’re learning, and talk about it right away. An education

industry blogger, Marianne Stenger, wrote for OpenColleges that “[d]iscussing what you’ve learned, whether immediately or a few days down the line, is important because it forces you to actively process the material…whenever possible, try to participate in group discussions where you’ll have the opportunity to go over the material you’ve learned, gain new perspectives and discuss any potential misunderstandings.” This means the 15-minute break after learning a new, complex concept isn’t necessarily the time to plan bar-hopping in Houston; it’s the time to talk about the new, complex concept. If that sounds harsh, consider who’s paying for your time in Houston. Is it the asphalt company for whom you work? Then you’re on company time in between educational sessions, just as you’d be on company time in between haul truck arrivals at the paving site; talking about improving your paving skills is not far-fetched. Ameritech College of Healthcare listed six methods that are proven to help college students retain information. I’ll paraphrase them here: · Teach the information to another person. By explaining a concept to someone else, you have to truly understand it yourself. (PsychoTactics.com stated “learners” retain about 90 percent of what they learn when they immediately turn around and teach it to someone else.) · Learn/train during the time when you are most alert. This means you get in tune with the times of day when you’re at your best. · Focus on one topic at a time. This means multi-tasking isn’t always the best option when trying to learn something new. · Take time to learn bits and pieces, rather than rushing through reams of material. · Write down notes. The tactile experience will help you kick different parts of your brain into gear. You can also read aloud or repeat a concept out loud—see method #1 above—to engage a different part of your brain. · Personalize what you’re hearing/learning to make it more interesting to you and easier to remember. You’ve got this perfect opportunity to meet with manufacturers on the tradeshow floor in the convention center. You’ve got this perfect opportunity to take notes and ask questions during the seminars and sessions. You’ve got this perfect opportunity to discuss and share information and new concepts so that you cram more than the base 80 percent into your brain for the upcoming season. You’ve got this.

Asphalt Drum Mixers

That’s a good idea

When setting the angle of attack, make adjustments carefully. You’ll turn the bolt a quarter of an inch and then double-check the nose of the screed. You won’t need large adjustments.

Check the Angle of Attack The screed is supposed to float along, smoothing out the mix in an even, beautiful black lane. When the screed tilts sharply to the front or back, it will affect material placement and experience wear and tear on the bottom of the screed plates. These are not good things to have happening if your goal is a top quality pavement. First: You want the screed plate to start out level, flat, and almost parallel with the ground. There will be about an eighth of an inch of angle at the front of the screed to accommodate the mix. You will begin with the tow point cylinders centered—at zero— and then adjust them up or down to get the correct angle of attack for the day’s paving. Once they are set, you shouldn’t have to change them. If making adjustments later in the paving day, do so carefully. When you adjust the tow point cylinders up, the tow arms will lift slightly. This will cause the front of the screed (the nose) to rise. This will cause down-pressure on the back end of the screed (the trailing edge). Think of a water ski. When the front goes up, the back goes down into the water. If you adjust the tow point too quickly, making an erratic change, this causes the trailing edge to lower into the mat. It will drag and tear until the screed levels out. When you adjust the tow point cylinders down, the tow arms will lower slightly. This will cause the front of the screed (the nose) to lower. This will cause the back end of the screed (the trailing edge)

66 // March/april 2018

to rise or lift. You’re not screeding off the material now. There’s no pressure on the material, yet you want that compression. Having no pressure on the mat with the back third or two-thirds of the screed plates, the nose of the screed will dig in, and you won’t get uniform material coming off the back end of the screed. These phenomena also cause uneven wearing on the front or back sections of the screed plate. To protect the equipment and the mat, you want to double-check the angle of attack before you take off. You want to set the tow point cylinders so that the screed is positioned properly for the mat you’re going to lay. Also make sure the depth crank is leveled off. Next: Get on your hands and knees and use a level, a straight edge, and a tape measure to double-check the screed plates are level, and to determine which section needs adjusting. If the nose is low, figure out why. Fix it. Clean it so you can tell if there’s been damage to the metal already. If the trailing edge is what’s low, again, figure out why and get it adjusted before you try to place the mat. – BY JOHN BALL

New and Updated Paving Equipment for 2018 World of Asphalt/AGG1 2018 is here, so original equipment manufacturers (OEMs) are hard at work putting the final engineering touches on products they’ll introduce in Houston this month. One of those OEMs is Hamm, with North American headquarters in Antioch, Tennessee, introducing a new concept for fuel-efficient compactive efforts. Read about that on page 72. Another is Ammann Group with headquarters in Langenthal, Switzerland. The manufacturer reported that users applaud improvements in versatility, reduced hand-arm vibration and low sound levels in its plate compactors. For example, Christian Jordi of Witschi Bau, a construction company also in Langenthal, Switzerland, tried out the Ammann APF 15/40 forward-moving vibratory plate compactor in both soil and asphalt applications. “The new APF plate is perfect due to its flexibility in both applications,” Jordi said. Jordi and other Witschi Bau operators also commended the new plate compactor for a reduction in unwanted vibration. The improvement was noticeable when compacting soil and aggregates. It became more apparent when working on asphalt. Jordi noted the machine’s productivity on asphalt, as it was able to quickly reach compaction goals on a parking lot project. The new plate was quieter, which was immediately apparent to Jordi. It was so quiet that other workers on the site noticed the reduced sound level. The APF 15/40 is one of five new Ammann vibratory plates that provide compaction power, maneuverability, forward-moving speed and climbing ability. The product line is known for reducing unwanted vibration to operators, as noted by Jordi. The new models are the Ammann APF 12/33, APF 15/40, APF 15/50, APF 20/50 Hatz and APF 20/50 Honda. They are the lightest of all Ammann plate compactors, with weights from 69 kg to 107 kg and widths of 330 mm to 500 mm. The plates fit a broad range of applications, including road repairs.

68 // March/april 2018

The APF 12/33, 15/40, 15/50 and 20/50 vibratory plates from Ammann Group offer reduced unwanted vibration to the operator and improved versatility on the job. They are available with an optional water sprinkler, making them suitable for asphalt jobs, like Jordi’s parking lot project. A Vulcolan mat protects paving stones during compaction. Honda petrol engines power the APF line. The largest plate, the APF 20/50, is available with a Honda petrol or a Hatz diesel engine.

The new HD+ 90i PH will be available in 2018 with hydraulically-assisted hybrid power train.

HAMM

At WOA, Hamm will introduce to North America its unique PH hybrid power train system for tandem asphalt compactors in the HD+ 90i PH tandem roller. This concept combines the traditional internal combustion engine with a hydraulic accumulator. The internal combustion engine covers the base load while a hydraulic accumulator meets peak loads. Hybrid solutions combine two power technologies. In the automotive sector, combinations of internal combustion engine and electric drive in particular are common. Hybrid power attempts with electric motors in rollers proved unconvincing, so Hamm tackled this problem with a novel approach, combining an internal combustion engine with a hydraulic system, and became the first roller manufacturer to develop a technical solution suitable for series production. For the first hybrid power models, Hamm chose the HD+ 90i, a popular tandem roller in the medium weight class. Up to now, this roller has operated with a 114 horespower (85 kW) diesel engine complying with EPA Tier 4 Final exhaust emission standards. A detailed examination of the actual engine load during compaction showed the Hamm developers that the peak loads were only needed occasionally

and even then for just a few seconds. This is the case when the roller starts up or the vibration / oscillation is activated. In the new hybrid power roller, these brief peak loads are handled by a hydraulic system, enabling the roller to be equipped with a smaller diesel engine for the same performance. The load on the diesel engine is also reduced in that the radiator fans are electrically operated for optimum efficiency. The hydraulic system works rather like a pumped storage power station: as soon as the power demand falls below the maximum load of the internal combustion engine, a pump fills the hydraulic accumulator. If a great deal of power is called for, such as when starting the vibration drive, the hydraulic system functions as an auxiliary drive, able to supply a maximum short-term load of up to 27 hp (20 kW). Following this, the cycle begins afresh with the refilling of the accumulator. The principle functions because for normal applications, the maximum load is only called up for a matter of seconds. Afterwards there is sufficient time to replenish the accumulator. The 9-MT HD+ 90i PH roller can be powered by 74 hp (55.4 kW) engine in place of a 114 hp (85 kW) unit—and with the same compaction power, according to the man-

ufacturer. The smaller engine does not require an SCR catalytic converter or DEF fluid. This results in advantages in terms of handling and maintenance. What’s more, the power train is markedly quieter. Last but not least, the hybrid power train in combination with the electric fan drives and a start-stop system enables savings of up to 15 percent in fuel consumption. This also substantially cuts CO2 emissions. The hybrid system underwent field trials in selected markets during 2016 and 2017 and is expected to be available in North America with double vibration (VV) and vibration-oscillation (VO), as well as the smooth drum-pneumatic “combi” rollers (VT) as options in 2018.

Prevent Sexual Harassment at Your Company Sexual harassment and misconduct seem to be present in every industry. You train your workers on its definition and what to do if an employee is a victim. Rarely do employees report incidents. When they do, it could cost your business time and money to resolve an issue. Some persons choose to leave employ rather than confronting the matter. As an employer, what should you be doing? “Sexual harassment” is unwelcome conduct of a sexual nature that is sufficiently persistent or offensive to unreasonably interfere with an employee’s job performance or create an intimidating, hostile or offensive work environment. It can be quid pro quo or hostile work environment. It can be overt, unwelcome physical advances, or verbal or psychological in nature. An action can be based on one incident or aggregation of a series of incidents even if one action in the series would not be harassing. First, as an employer you need to understand your risk. Keep in mind that an employer can be held strictly liable for the actions of an employee who acts as a supervisor. Such strict liability is detailed in Title VII of the Civil Rights Act of 1964, 42 U.S. C. §2000e, et seq. Many States and local municipalities follow the Civil Rights Act. In Nischan v Stratosphere Quality LLC, 865 F. 3d 922 (U.S. Ct. App. 7th Cir. 2017), the Court set out the elements that generally must be proven to establish a claim of sexual harassment against an employer. The claimant must show “(1) he [or she] endured unwelcome sexual harassment, (2) he [or she] was harassed because of [his or] her sex, (3) the harassment was so severe or persuasive that it altered the conditions of employment and created a hostile working environment and (4) there is a basis for employer liability.” Also, there must be a determination whether the alleged harassment was done

76 // March/april 2018

by the supervisor or the person’s co-worker. If the supervisor is the alleged perpetrator, then the employer is strictly liable for the harassment. If the harassment was by a co-worker, the employer “is liable only if it was negligent in discovering or remedying the harassment.” Thus, an employer must act appropriately once it has notice, actual or constructive, of misbehavior.

Keep in mind that an employer can be held strictly liable for the actions of an employee who acts as a supervisor. Sexual harassment is a difficult topic and the subject may be embarrassing to discuss for some people. It seems that every day we hear about another sexual misconduct case. If you are like most businesses in the United States, you already conduct training to prevent sexual harassment at least once a year. Most employers conduct this anti-harassment training to meet the minimum standard to avoid liability. We all know those individuals in the organization that belittle the training process or tell inappropriate, off-color jokes. Although this sexual harassment training has been successful in communicating basic information on what it is and where to report, it is less effective in stopping the behavior. You can foster a respectful work environment and create training that communicates that your organization is serious about stopping sexual harassment. You need to take two actions: (1) have impactful, informative training that educates on prohibitive behaviors and (2) create a culture of accountability, equality and respect.

It is crucial as a business that you take the topic seriously. Here are some actions you can take: • Start your training by putting participants at ease, convey the seriousness of the topic. Don’t laugh at any attempt by the naysayers to belittle the process or laugh or smile at jokes. • Recognize that the standard training often reinforces the stereotypes that men are the powerful harassers and women are victims. • Train your managers and supervisors separately from your employees. Train the managers and supervisors to listen and not be dismissive. Use construction-related scenarios to highlight behaviors that constitute misconduct as well as legally actionable harassment. Stop the slide down the slippery slope. • Encourage civility in the workplace and treat all employees as equals. • Empower and train the bystander to stop the harassing behavior; not by putting themselves in harm’s way, but by diffusing the situation or identifying the behavior in a non-accusatory manner. • Support the victim and talk to them about the interaction. Encourage civility and a speak-up culture. Promote women. Culture has much to do with whether your employees will come forward to report bad behavior. As an employer, learning about misconduct before it morphs into a major liability is key. Train to stop the behavior and not just to avoid liability. – BY LORRAINE D’ANGELO

Mitigate Operator Fatigue with a Wristband When scanned, the Cat Smartband tells what level and quality of sleep the worker has had, and what percentage of risk the worker poses to the job at hand.

When a driver becomes fatigued, the DSS detects it and alerts the driver through seat vibration and/or an audio alarm. Switching from nighttime to daytime paving, working long hours in one cab or any number of off-the-job factors can result in worker fatigue during the job. When project activities require operation of heavy equipment, it’s essential that workers remain alert not only for their own safety, but also for the safety of colleagues in the area. To assist workers and managers in assessing when a worker has become fatigued while operating machinery or injured somewhere on a jobsite, safety-minded technologies step in. In a recent Insurance Business Magazine article titled “Wearable Tech Cuts Costs in Construction,” the authors discussed a sensor technology from Triax Technologies of Connecticut, specifically. The report stated the Triax sensor is designed to be worn on a tool belt, thus can track workers’ whereabouts with an emergency locator button in the event of accidents or injuries. The technology is set up on a site using a “mesh” Internet system to connect all areas online; from there, the site’s safety personnel can view what’s going on. The COO for Triax, Pete Schermerhorn, explained that the sensors are aware of the worker’s position. If a worker slips or falls on the site, within the virtual grid, the sensor knows it and sends an automatic notification to a site supervisor. Schermerhorn explained that the system will log how far the person fell, where the person fell on the site and who else was nearby. Human Condition Safety also has a trackable device, according to Insurance Business Magazine, which is embedded in the construction worker’s vest. It is designed to monitor the worker’s movements in any high-risk areas. A company that may be more familiar to readers, and which has a fatigue-monitoring device in its safety arsenal now, is Caterpillar. The company shared with AsphaltPro:

78 // March/april 2018

“The Cat system (developed by Seeing Machines and acquired by Caterpillar) is very popular for large mining trucks, which operate 24 hours a day with drivers often working 12-hour shifts. The system is finding its way into smaller trucks and smaller operations (i.e. aggregates) as the problems presented by fatigue become more widely known and understood. Caterpillar also offers a remote monitoring/fatigue assessment service as well as fatigue/shift work training through Caterpillar Safety Services.” The device is a Cat Smartband, worn as a wristband, that can be scanned when the worker arrives on site. It “tells” what level and quality of sleep the worker has had, and what percentage of risk the worker poses to the job at hand. Then the Driver Safety System (DSS) provides real-time driver fatigue intervention—the incab monitor keeps its eye on the operator. When a driver is distracted or begins to drift off to sleep behind the wheel, an in-cab alarm and seat vibrator alerts the driver at that moment. The system also sends an alert to the fleet monitoring center to help the company mitigate fatigue and distracted driving events.

Here’s how it works: “The fatigue technology works by monitoring eye-closure duration and head pose. If the Driver Safety System detects a fatigue or distraction event, the operator is immediately alerted through configurable in-vehicle seat vibration and/or audio alarm. The driver fatigue or distraction event detected by the Driver Safety System is sent to a 24-hour monitoring center to classify and confirm the event. Caterpillar experts will analyze the data and provide customized reporting with site-level recommendations. By cross-referencing fatigue and distraction events against available equipment data, Caterpillar can provide suggestions to improve operational efficiency such as hard breaking and over speed.” The goal, of course, is to protect workers. But the system also has a goal of improving operations by allowing operators to focus on their jobs; eliminating requirements to interact with the system.

Here’s how it works

Astec’s Generation 3 Warm-mix System As the industry’s use of warmmix asphalt (WMA) increases, options for foaming the liquid asphalt cement (AC) meet new technology. The team from Astec Industries, Chattanooga, Tennessee, released the Generation 3 warm-mix system December 2017 to allow producers to make WMA mix designs without chemical additives. Here’s how it works. The Gen3 apparatus is installed inline so the heated liquid AC enters the system

82 // March/april 2018

easily. It uses a flow splitter plate to ensure the AC encounters both water spray nozzles in the system. As the liquid AC enters the Gen3 manifold, it is directed above the splitter plate adjacent to two water injection valves.
