SMART APPS
FOR
PAVING
Software Puts More Power in Hand By Jeff Winke CEG CORRESPONDENT The before-you-leave-the-house checklist for everyone is likely wallet, keys and phone. One feels naked without any of these. But with the accelerated evolution of technology, it is inevitable that smart phone and tablets will soon replace the wallet and keys. The evidence is there. Carrying cash — and certainly a pocket of jingling change — is already all but taboo for anyone under the age of 30. Soon the debit card will become passé. The smart phone will replace currency and charge cards as the means for paying. Case in point: Wired magazine on its 12/3/14 news posting highlighted a new Starbucks iPhone application or app where a customer can order and pay for drinks before setting foot in the door. A customer bypasses the order-pay line and picks up the drink knowing from the confirmation text that the black coffee or whatever-chino would be ready seven minutes after the order was placed. Fingerprint recognition door locks are already here. For automobiles, watch for passive keyless entry and keyless start-up via a cell phone to replace the physical car key and key fob. There has been a steady shift in the traditional pillars of the mobile economy, from telecommunication services and mobile devices to mobile apps. This emerging component of the value chain is called the “mobile app economy” and it represents the fastest growing area and will continue to do so in the foreseeable future. In 2013, The Wall Street Journal reported that apps have exploded since Apple Inc. kicked off the mobile-apps craze five years earlier. WSJ states that apps have rocketed toward $25 billion in sales with the app stores run by both Apple and Google that offer more than 700,000 applications each in their respective stores. It is not surprising that the asphalt paving market is benefiting from the development of apps for smart phones, tablets, and even smart watches. Available now are asphalt quantities calculator apps, which can be purchased for about $0.99 each — far less than a cup of froofroo coffee.
These asphalt calculator apps for smartphones are designed to simplify the paving process by calculating how much asphalt is needed to pave a given area. One app calculates the amount of cubic yards and the hot mix tonnage needed for a given job once the user inputs the length, width and thickness of the area. This application also offers an optional cost calculation feature. Another app calculates volume, in both cubic feet and cubic meters, as well as tons of asphalt mix needed for a job. It calculates the amount of asphalt required based on length, width and thickness of the area, and it also determines the cost of the asphalt. The app does not require an Internet connection for use; it automatically saves the inputs; and allows the user to send calculations and conversions via e-mail. Most of the asphalt calculator apps work on Android devices as well as the Apple array of products including several generations of iPhones, iPod touches, and iPads that are running iOS 4.3 or later. Beyond the numerous asphalt calculator apps, there are a variety of mobile applications designed to assist in the planning of paving and compaction jobs. These apps are designed to walk the paving contractor through the planning process with the intent of creating a more efficient job site. One app, called Asphalt Pro, includes the usual material and cost estimator, but goes steps further than other mobile apps by including a comprehensive suite of tools for use in the field. Tools to match workflow and inspection practices in the field include: mix yield underrun/overrun calculators; tack and seal distance calculators and rate validators; and visualizers to balance plant, truck, paver and roller capacities. All functions, including the project documentation feature, can be e-mailed back to the office or a supervisor as part of the project records. This app includes a cost estimator for small projects, parking lots and change orders. It can calculate mix yield and
2
compare that yield to project estimates to help keep track of overruns or underruns. It can calculate tack and seal distances to assist in application operations, and verify rates for inspection duties. The Asphalt Pro app can make adjustments to any parameters in an effort to optimize production, improve efficiency, and reduce constraints. The app also can capture, organize and share digital images of issues that occur on the project as they happen. Included are six conversion calculators with units for every value a contractor and inspector would need in the field, in both U.S. and metric measurements. Another app calculates paving amplitude. The paving amplitude calculator app is designed to be a productivity tool that helps road construction professionals determine the proper amplitude setting for their asphalt compactor to improve their compaction efficiency. The app processes user inputs to provide a recommended amplitude setting and can be set up to work with a particular model/vibratory system to provide the right output. Add to the list of apps a contractor may wish to consider is a paving production calculator app, which is intended to assist asphalt paving contractors plan paving jobs by helping to estimate trucking needs, paving speeds, compaction and other factors. The production calculator app is designed to help optimize the job site and reduce inefficiency. There also is an asphalt paving checklist mobile app that provides some industry stansee APPS page 16

CASE Case Construction Equipment’s new Tier IV Interim DV209C and DV210C high frequency asphalt compactors represent the addition of two new machines to Case’s high frequency double-drum models, giving road builders more control and versatility to dial compaction performance to match the thickness and required density of each lift. The machines also are equipped with new, high-efficiency Tier IV Interim engines (cooled exhaust gas recirculation + diesel oxidation catalyst) with automatic idle control systems to improve fuel efficiency by as much as 10 percent compared to previous models. With operating weights of 21,030 and 22,730 lbs. (9,539 and 10,310 kg), respectively, and a standard drum width of 66 in. on both machines, the DV209C and DV210C are sized to suit most mid-size and large road projects. New features also include more maneuverability in the operator compartment for greater visibility, and a new color monitor and operator interface. Both machines feature large water and fuel tanks to allow the machine to work all day without fill-up, maximizing productivity. The Power of High Frequency The new DV209C and DV210C feature a frequency range of 42 to 55 hertz standard and 46 to 67 hertz high frequency. This higher frequency range gives operators control over compaction performance based on the thickness and density requirements of the lift. When combined with variable amplitude settings (.22 to .6 mm on the DV209C, .33 to .6 mm on the DV210C), these machines can be dialed in to better handle thinner lifts (low amplitude/high frequency) and thicker lifts (high amplitude/low frequency). Centrifugal force also can be dialed in (15,736 to 21,582 lbs. on the DV209C, 17,535 to 26,977 lbs. on the DV210C) to best match the thickness of the lift and the desired depth of compaction.
The new DV209C and DV210C feature a frequency range of 42 to 55 hertz standard and 46 to 67 hertz high frequency.
New Operator Station and Environment Improve Comfort and Control The new and spacious operator environment found on the DV209C and DV210C includes features designed to give operators better visibility to the work and easier control through intelligently placed controls and monitors. A new operator station that is capable of turning and sliding through the entire width of the cab gives the operator visibility to the drum surfaces and edges, as well as the spray bars. Large front and rear mirrors (with optional enclosed cab configuration) help ensure optimal visibility. The new DV209C and DV210C also feature a color monitor conveniently located in the center of the steering wheel to give operators easy access to important operational information, as well as controls for speed, frequency, vibration and sprinkler adjustments. The monitor stays in the same position, even when the steering wheel is rotating, for easy reading and control.

savings, programmable speed control, and the ability to independently control vibration frequency and amplitude to either drum. Drum-mounted LED lights are standard for improved illumination to all four drum edges. Unlike other machines, which require physical movement of weights on the side of each drum, which is hard enough to do in the daylight, let alone at night when most of the major highway work is done, amplitude and frequency adjustment on the HD+ models can be done by the operator on the control panel. Also unique is the HD+ Series’ offset capability, which on the HD+ models is close to 7 in. (17 cm). That means an operator can keep the front drum on the hot material and offset the rear drum so it can bridge between the pre-compacted hot material and the cold joint, potentially saving a pass for higher productivity, and avoiding travel in the other lane of traffic, for enhanced safety.

KASI INFRARED
Infrared technology expedites repair by heating, fusing, and compacting recycled asphalt, saving equipment, labor, and new material in the process.
Potholes, trench cuts and other asphalt repairs are the bane of property managers, public works managers and road crews . . . ubiquitous, time-consuming, expensive to repair, tie up traffic and are hazardous to passenger cars, trucks, cyclists, skaters and pedestrians. KASI infrared asphalt repair technology enables property managers, city, county and state road crews to save time, material and labor costs in repairing hazardous potholes, alligator cracking, failed utility cuts and other surface defects that plague their asphalt streets and parking lots — year round. The infrared technique also provides repairs to roads, parking lots and driveways at savings of up to two-thirds the cost of conventional methods. As opposed to conventional repair, which requires the removal of old asphalt from a damaged site and its replacement with new asphalt, infrared technology expedites repair by heating, fusing, and compacting recycled asphalt, saving equipment, labor, and new material in the process, according to the
company. The KASI infrared system has enhanced operations by reducing repair time and allowing repair of larger surface areas. It also does a better repair then just filling a pothole or alligator cracking with new asphalt. A road crew can load up a couple of tons of asphalt and be busy all day. In addition to saving time, infrared repair technology enables crews to recycle a substantial portion of the old asphalt, saving on materials costs as well. While public safety from road hazards is always a high priority, exposure to liability claims also may be important to many property management companies and local governments, particularly those who are self insured. Potholes and other types of failures have to be taken seriously. It doesn’t take much to create a hazard. It could be cracks or potholes or any type of imperfection. Infrared equipment has a unique capacity in overcoming asphalt failure problems quickly. You simply drop the heater on it, heat it up for awhile, rejuvenate much of the old,
15
damaged asphalt, and then you resurface and seal it. The road surface is pretty much back to new when the process is completed. Using an infrared asphalt reclaiming and repair system, the savings on labor and repair time as well as materials are very substantial. Infrared restorations fuse to the existing pavement, creating a continuous surface. This eliminates the need for tackcoating the edges because the seams have been eliminated, enhances durability, and allows roads to be opened to traffic immediately. It also makes the repair process less expensive, since existing asphalt is recycled, crew size is typically limited to two; and only a single truck or trailer is used, according to the manufacturer. KASI’s infrared asphalt repair equipment is commonly used by both public and private maintenance/transportation managers for asphalt repair of pot holes, utility cuts, trenches, depressions, joints and other irregular pavement issues.

APPS from page 2 dards that are helpful in cases of asphalt paving on private land, such as residential driveways — as opposed to public street paving. Typically, there is no written residential standard that clarifies trade custom or defines any deficiencies commonly found in defect claims. Local building codes typically do not address paving installation. An asphalt paving checklist mobile app may be helpful when reviewing the site in preparation for starting an asphalt paving project. To teach and aid the hot mix asphalt (HMA) technician on how to properly inspect HMA paving operations there is a hot mix asphalt paving inspection mobile app. The emphasis is on acquiring the skills and knowledge required to conduct the inspection to ensure construction of quality pavements that conform with the plans and specifications. The app covers: industry terminology, duties, daily tasks, chain of command, and contractor safety. Additionally, there are other helpful apps that are not paving production specifically, but have an impact on the workday. OSHA has a helpful heat safety app to tell if

it will be too hot for employees to work the day. It gives the “heat index,” which is a single value that takes both temperature and humidity into account. The heat index is a better measure than air temperature alone for estimating the heat risk to workers. The app combines data from the U.S. National Oceanic and Atmospheric Administration with the geographic location to determine necessary protective measures. Based on the risk level, the app provides users with information about precautions they may take, such as drinking fluids, taking breaks and adjusting work operations. Users also can review signs of heat stroke, heat exhaustion and other heat-related illnesses, and learn about steps to take in an emergency. Users can also contact OSHA directly through the app. A handy construction punch list app allows the user
16
to manage a project to-do list on-the-go. Before the day begins, a paving or milling contractor can view the day’s task list and make priorities. For the contractor, it can save on the administrative time for taking notes, typing them up, and e-mailing then out from a computer. A project team can communicate faster and more effectively from anywhere. It is also possible to email a PDF with picture included or a spreadsheet (CSV file). Spreadsheets can be sorted by number or status with the app. And there’s the ability to add comments as needed to each item. The INRIX Traffic App can help plan the best routes to job sites and reduce the chances of getting snarled up in traffic, which can save time and fuel.

The past decade has yielded an exponential rise in the price of both hotmix asphalt and cold patch material. The rising prices have resulted in many pavement industry professionals seeking alternative solutions to expensive plant mix and cold patch. Two alternatives industry professionals have begun moving toward are the processes of reclaiming and recycling asphalt. For some recycling and reclaiming are thought to be the same, however this is not true. Reclaiming asphalt is the process of bringing properly stored plant mix or virgin asphalt up to a workable temperature (300F to 350F) by means of a static heat source over a period of usually 8 to 10 hours. During the reclaiming process no additional ingredients are added because the virgin mix still encapsulates all necessary ingredients from the plant to ensure you end up with a quality mix. Reclaiming asphalt is done in a hotbox reclaimer. A hotbox reclaimer will give you the ability to not only reclaim but also maintain hotmix at a workable temperature by means of a thermostatically controlled heat source for up to a period of three days. What this means is you no longer have to throw away your unused asphalt at the end of the day, instead you can keep it in your hotbox reclaimer and use the remaining load at another time, immediately saving you money. An asphalt reclaimer also gives you the ability to bulk store virgin asphalt while the plants are open and then reclaim it when the plants are closed, lessening your dependence on cold patch while the plants are closed. The benefit of owning a hotbox reclaimer is you can buy what you need and use what you buy. Recycling asphalt is the process of taking previously considered “junk asphalt” (asphalt millings chunks, etc.) and returning it to its original temperature and consis-

tency. Recycling asphalt is achieved by first drying out and breaking down the aggregate by adding heat and agitation (mixing and tumbling), then once the aggregate is broken down and dried, asphalt cement is added as a binding agent. The asphalt cement must be uniformly introduced in the mixing process to ensure the asphalt cement evenly encapsulates the aggregate. What you are left with after about 15 minutes of heating, tumbling and mixing is a plant quality batch of hotmix asphalt. Contrary to popular belief asphalt recycling cannot be done in a hotbox reclaimer and there is no such thing as a hotbox recycler. The recycling process can only be achieved through a true asphalt recycling machine. Recycling asphalt is beneficial whether you are a contractor or municipality. An asphalt recycler will lessen your dependence on the plants and give you the ability to transform your mountains of millings into plant quality
18
mix at a fraction of the plant price. With an asphalt recycler you have the ability to produce and use hotmix at anytime and anywhere. Before making the investment in a hotbox reclaimer or asphalt recycler, make sure you stop and think about what you are truly trying to achieve. Do you want to reclaim and transport virgin asphalt or do you want to recycle “junk asphalt.” It is important to not just know the difference but also to understand the difference to ensure you are purchasing the piece of equipment that will help you achieve your ultimate goal. We suggest you demand a demo, and get a firsthand look at the processes and the equipment used to perform them. For more information, call 800/4921757 or visit www.kminternational.com.

APPS from page 16 delays, and closures, and the ability to compare the fastest routes. The app also has the ability to share arrival times with the office, coworkers, and family. Additionally, it is possible to receive live traffic alerts about traffic delays, based on current location and preferences. One final organizational app that may come in handy is Evernote. The app allows contractors to take notes, capture photos, create to-do lists, record voice reminders — and makes these notes completely searchable, whether at home, at work, or on the go. A user can save, sync and share files across the computers and devices they use. For those plugged into social media, it is possible to save tweets to the Evernote account or if work was done on a unique job that day, the user could take photos of it and share to the business Facebook followers. As the pace technology is evolving, it appears as though in the near future the before-you-leave-the-house checklist for everyone in the morning will likely be: phone, tablet, smart watch — pick one! Because they are all synced and any one of the devices will cover all needs, life and work will be simpler (we hope.)

drums, allowing greater utilization of the roller. No need to carry multiple rollers to the job site to switch between vibe- and novibe paving. No more oscillating rollers sitting on the yard waiting for the next novibe/oscillatory spec. Full-utilization means a better investment from the top down, according to the manufacturer. In addition to greater utilization, the ND Series offers better methods, featuring gear-driven oscillation eliminating the need for expensive, time-consuming beltmaintenance. With a slightly reduced oscillation amplitude, a higher frequency and oscillation coming from both drums instead of just one, you can also speed up your paving train and still maintain compaction and smoothness efforts. In addition to its vibratory pneumatic and oscillation systems, Sakai also will be introducing a 54-in. (137 cm), 4.5-ton (4 t) class roller, the SW502W-1. Featuring ECO-mode, the operator can save fuel usage on smaller paving jobs as well. An addition to the SW502 Series rollers, the SW502W-1 bridges the gap between the 47-in. (119 cm) roller class and the 58-in. (147 cm) roller class, giving a wider range to compaction specialty. Intelligent Compaction Sakai has been offering intelligent compaction systems for more than 10 years. Sakai’s CIS2 system allows for informed decision-making on real-time changes in the compaction process to achieve more uniform and successful compaction results. Teaming up with Topcon to offer the greatest in display and GPS offerings, our CIS2 system offers contractors the ability to ensure complete compaction coverage and uniformity of the job, according to the manufacturer.

The S-4XL is a full featured, mechanical broom street sweeper mounted on a non-CDL chassis. It offers an oversized high productivity 4.5 cu. yd. (3.4 cu m) hopper that dumps anywhere from frame level to 12 ft. (3.6 m) in height and has up to 12,000 lb. (5,443 kg) lift capacity.
The Starfire S-4XL from the StewartAmos Sweeper Company is built to tackle tough jobs day-in and day-out from sweeping millings to city streets to busy highways. The S-4XL is a full featured, mechanical broom street sweeper mounted on a nonCDL chassis. It offers an oversized high productivity 4.5 cu. yd. (3.4 cu m) hopper that dumps anywhere from frame level to 12 ft. (3.6 m) in height and has up to 12,000 lb. (5,443 kg) lift capacity. An extended reach 44 in. (112 cm) hopper dump door makes truck/container dumping faster, cleaner and safer. Flexible joints protect the door and dump cylinders
against impacts. A three zone dust suppression system and 330 gal. (1,249 L) water tank ensure environmentally friendly dust free sweeping. The S-4XL sweeps a 10 ft. (3 m) path with 42 in. (106.7 cm) gutter brooms or up to 11 ft. (3.4 cm) with 54 in. (137 cm) gutter brooms. The main and gutter brooms are spring balanced and full floating. They automatically apply the right amount of surface pressure and follow surface contours for a cleaner sweep. This means no operator judgments. They are free to focus their attention on safe driving. All six Starfire mechanical broom models including the S-4XL are equipped with
23
a three shaft elevator system. This design extends elevator service life, reduces maintenance costs and improves pick-up performance, according to the manufacturer. It also has four massive “X” style lift scissors that ensure hopper stability when dumping wet, unbalanced or sticky loads. The S-4XL is mounted on a 25,950 lb. (11,771 kg) GVWR chassis equipped with “low profile” tires. This makes the unit extremely maneuverable and tight turning. For more information, call 800/4822302 or visit www.stewart-amos.com.
