FROM THE EDITOR 2021 SHOWING SIGNS OF RECOVERY FOR CONSTRUCTION INDUSTRY

R

emember a year ago when many of us got home from CONEXPO and entered into lockdowns because of the growing concerns over COVID-19? Remember how we all said “It’s only for a few weeks and then things will be back to normal?” Perhaps we were a bit hasty with all that.

The fact is that 2020, and the start of 2021, have continued to be very strange. We remain hopeful that it will only be a few weeks and then things will be back to normal, and this time there are vaccines and positive trends to help us along – but the world remains very different than it did at the beginning of 2020.

From an economic standpoint, the past year has been a firm kick in the teeth for many industries. Construction has managed to keep moving forward, to some extent, with new safety measures and regulations in place for job sites of all kinds.

Even so, it’s been a challenge to keep moving forward. Now, though, we appear to have some indications that 2021 will be a year of recovery for contractors and the manufacturers that rely on them.

A new survey from the Association of Equipment Manufacturers released recently suggests that there’s a positive trend among its members. The study found that a majority of respondents – 55 percent – are expecting sales to either remain stable or increase despite continuing pandemic effects. The survey, which invited responses from employees of AEM member companies, features responses from more than 130 recipients that range from the C-suite to sales and operations departments, the AEM states.

“The equipment manufacturing industry has continued to operate throughout the COVID-19 pandemic and has successfully adjusted to challenges to make the equipment that builds, feeds and powers our country,” said AEM president Dennis Slater.

Of the responses, 19 percent said sales are up while 36 percent indicated stable sales, with strong pipelines of orders, increases in customer demand, robust economic rebound, customers with essential status, and a level playing field due to no travel being behind sales levels. About half of respondents did indicate drops in sales, from supply chain disruptions, reduced demand, limited international sales, cancelled projects and other challenges.

More broadly in Canada, construction is expected to rebound this year and continue to rise, though at muted levels. A forecast from BuildForce Canada says construction employment is expected to rise by 64,900 workers over the next decade, an increase of six percent over 2020 levels.

“Canada’s construction outlook is strong for 2021 and well into the middle portion of the decade, thanks to gains in the

It’s been a challenge to keep moving forward. Now, though, we appear to have some indications that 2021 will be a year of recovery for contractors and the manufacturers that rely on them. residential and non-residential sectors,” said BuildForce Canada executive director Bill Ferreira.

The non-residential sector should lead the way through 2023, driven by public transit, health care, education, roadwork and other civil infrastructure projects, BuildForce projects. Quebec, Ontario and British Columbia can be expected to take the lead in growth, the report suggests.

All of that improvement is somewhat dulled by the fact that by 2030 there is likely to be a significant gap in the workforce – retirements are expected to outpace recruitment by upward of 31,000 workers. With growth in demand, that could mean a gap of up to 81,000 by 2030. The need for recruitment, training, apprenticeship programs and other approaches is evident in our industry.

Overall, 2021 looks like it could be a step forward from the slowdown that we saw in 2020. There are positive signs of growth on the horizon for construction and equipment manufacturers – let’s keep that in mind as we work through the final stages of this pandemic.

heavyequipmentguide.ca | APRIL 2021

onstruction requirements across Canada are expected to rebound in 2021 in the wake of the COVID-19 pandemic and rise through the coming decade – albeit at more muted levels than in the past 10 years.

Activity across the Atlantic provinces is expected to vary.

Newfoundland and Labrador will see a modest recovery through 2021, but long-term growth will be constrained.

The forecasts for New Brunswick and Nova Scotia will be bolstered by in-migration trends. Prince Edward Island was the only province of the four to experience a rise in construction employment in 2020, which is expected to continue through 2022.

Quebec’s market is expected to rebound from the pandemic in 2021 and grow through 2024 on the strength of private-sector spending and strong levels of government investment.

Ontario will be driven by a growing pipeline of major infrastructure projects across all regions. An additional recovery in commercial and industrial investment will bring labour demands to a peak in 2026.

In 2020, Manitoba experienced its first year of negative construction growth in several years. Declines in major-project requirements and lower levels of institutional and residential growth may cause employment levels to drop slightly over the forecast period.

A broad-based recovery is expected for Saskatchewan in 2021, as education, health care, utility, and mining investment combine to boost growth across most construction segments to an expected peak in 2023.

Alberta, which was among the provinces hardest hit by the pandemic, could see further challenges ahead. Ongoing uncertainty in the energy sector and further deferrals and cancellations of major investments have significantly tempered expectations for a strong near-term recovery. A more material expansion is expected after 2023.

British Columbia is poised to enter the steepest period of growth. The province will add more than 11,400 non-residential workers through 2022. By 2030, employment is expected to increase by 9,900 workers compared to 2020.

CAA STUDY SHOWS POOR ROAD INFRASTRUCTURE COSTS CANADIANS $3 BILLION ANNUALLY

C

anadians are paying $3 billion every year in higher vehicle operating costs due to poor road infrastructure, according to a new study conducted by the Canadian Automobile Association (CAA).

This study is the first in Canada to show the cost to vehicle owners of poor roads, rather than focusing on how much it costs to build or repair them. CAA’s analysis revealed the average Canadian driver incurs an extra $126 in costs annually due to the poor quality of roads – a total of $3 billion for drivers collectively. That cost comes in the form of more vehicle repairs, higher maintenance and other operating expenses.

The study uses self-reported data from provincial and municipal agencies, who indicated that close to half of Canadian roads are rated below average. Using the most recent data available from Statistics Canada, the study finds that spending one dollar on pavement preservation eliminates or delays spending of $6 to $10 on costly repairs later.

The analysis in this report corresponds to a typical year using the most recently available data. The report assumes a steady use of roads and kilometres driven by Canadians, as opposed to the unusual drop in traffic volumes that has accompanied the COVID-19 pandemic.

TRADE SHOW UPDATES

W

orld of Concrete will be the first large show to return to Las Vegas, pending the approval of the Large Gathering Certification by the Department of Business and Industry. It also represents the first large-scale trade show to return to the U.S. market since the pandemic halted in-person meetings. World of Concrete will be held June 8–10, 2021.

The Utility Expo (formerly ICUEE) is already set to be the biggest utility trade show ever, breaking the record set by ICUEE 2019 with nearly 1.3 million square feet of exhibit space already sold. A new outdoor layout will also allow for more new product introductions and demonstrations. The Utility Expo will be held September 28–30, 2021.

Following a review of the Government road map to ease COVID-19 restrictions, the QMJ Group has made the decision to postpone Hillhead by 12 months. By delaying the show until June 2022, the benefits of a completed vaccination program will have taken place, allowing for a safer event.

Volvo CE has dropped out of bauma Munich 2022, instead choosing to follow a new marketing approach that will combine physical, digital and hybrid events. The move will allow for a more flexible, tailor-made offer that will cater to however the customer wants to interact with Volvo products.

IN-DEPTH REPORT: COMPACT WHEEL LOADERS

C

ompact wheel loaders have evolved from material moving machines outfitted with bucket or forks to more versatile equipment with options for higher hydraulic flow and expanded attachment use, more operator comfort features, and steering configurations that can be matched to the job site. We spoke with experts from across the industry to get the scoop on the latest options for compact wheel loaders, as well as application benefits and how these machines compare to skid-steer and compact track loaders.

WHAT APPLICATIONS BENEFIT FROM COMPACT WHEEL LOADERS?

Compact wheel loaders pick up where skid steers and compact track loaders leave off in essential metrics like lift capacity, ground clearance, cab height/visibility and application versatility, according to Brad Stemper, North America product manager for compact construction equipment at CASE Construction Equipment. Choosing a compact wheel loader over a different type of compact equipment will depend on factors such as material weights, truck height or hopper height, WHAT IS A COMPACT WHEEL LOADER? and target bucket size. These factors will also determine When looking at a range of manufacturers, the definition of the correct wheel loader size for an application; from there, what classifies as a compact wheel loader isn’t straightforward. application-specific options such as linkage, axle options and Like compact excavators, there is no standard across-the-board transmission type are available. definition for a compact wheel loader, as different manufacturCompact wheel loaders excel in a variety of applications ers use different metrics to define their lineups.

compact track loaders, and Ashton said that a compact wheel loader will usually have a longer service life compared to skid-steer loaders that may need replacement after four or five years. Quatro added that tires on compact wheel loaders don’t need to be replaced as frequently compared to skid steers.

Gardner from Kubota said that wheel loaders are more comfortable for operators and will cause less fatigue leading to greater productivity.

COMPACT WHEEL LOADER TRENDS

Industry experts have observed a number of trends in this category in recent years including size, operator features and attachment use.

According to Britton, wheel loaders weighing under 14,000 pounds are a growing category due to size and the benefits that come with being easier to transport as well as smaller and more maneuverable on tight job sites.

Stemper mentioned electro-hydraulic controls on CASE compact wheel loaders, which is a trend that carries over from its larger wheel loader line. “EH controls provide more opportunities for control enhancements in general, making the machine easier to use and increasing operator productivity.”

For example, “CASE recently launched EH controls for their loaders, hydrostat and brake system. The EH loader controls provide the opportunity to adapt operator customization to adjust the responsiveness of the lift and tilt functions for improved control, efficiency and versatility on the job site.”

Stemper added that bucket metering, which provides operators with more precise and consistent movement of the bucket edge while metering or sifting material into a truck, and an E-inching pedal to provide precise movements at slow speeds are trends for the compact segment.

Gribble sees the growth in the number of attachments that can be used with compact wheel loaders as the most significant trend of this product category, and high-flow capability offers more versatility.

“We’ve seen customers choosing compact wheel loaders to work in smaller spaces when a skid steer or compact track loader just isn’t right for the job. Because some of the smaller compact wheel loaders can now use a wide range of attachments, they can be just as versatile as a skid steer or compact track loader, but with a higher ROC and more power,” Padgett said.

“In general, the expansion of high-flow auxiliary hydraulics, advanced machine controls and available hydraulic attachments have made compact wheel loaders far more productive, versatile and easier to operate.”

ATTACHMENTS FOR COMPACT WHEEL LOADERS

Along with other compact machines, the growing number of attachments that are compatible with compact wheel loaders is a significant trend that contributes to these machines’ versatility, said Gribble.

The industry’s first wheel loaders were designed with the sole purpose of scooping material, moving it and dumping it. Today, wheel loaders can do so much more, noted Ashton.

When using a compact wheel loader, about 75 percent of the time the required attachment will be either a bucket or forks, according to Britton. However there are plenty of other work tools that are compatible with wheel loaders that will make them more versatile, such as cold planers, wheel saws and brooms. “At one point they could be performing a load and haul

Because the centre of gravity is not affected by the steering of the machine, the lifting capacity is not reduced at full turn with all-wheel steer. The off-road stability of the rigid frame makes an all-wheel steer loader a versatile and profitable addition to a fleet in high-speed construction applications.

Jay Quatro Field Application and Training Specialist, Wacker Neuson task, the next it can be cleaning the job site without the need for a secondary machine on site.”

“In the past, only skid steers and compact track loaders with high-flow hydraulics could be outfitted with attachments like snow blowers, snow blades and plows, sweepers. pickup brooms and grapples,” said Padgett. “Today, they can use all those attachments on their compact wheel loaders which makes it far easier and faster to get an excellent ROI on these machines than ever before.”

Skid-steer style couplers offer the advantage of outfitting the compact wheel loader with skid-steer and compact track loader work tools and Quatro said that most compact wheel loaders in North America have switched over to a universal attachment plate Gardner noted that Kubota wheel loaders are becoming much more popular for snow removal with the availability of snow blowers, snow pushers, hopper brooms and sweepers, and Britton added that another trend Caterpillar is seeing is large, configurable snow wings on compact wheel loaders for clearing larger areas.

Whether to select a compact wheel loader with four-wheel steer or articulated steering will depend on several factors, including size of the job site and needed steering angle, the surface type, maintenance considerations and application.

According to Gardner, while four-wheel steer will provide a tighter turning radius, it does require more maintenance. Articulated loaders are more durable on rough terrain.

Ashton echoed the maintenance concern and added that “With an articulated wheel loader, there is a sort of rule: when you have to turn right or left in narrow places and your bucket is not touching the wall or structure, the counterweight will also not touch. The outer positions of the machine stay in the same radius. That’s not the case with four-wheel steering.”

According to Quatro, articulated wheel loaders work well on hard surfaces due to lower tire wear because of the steerAPRIL 2021 | heavyequipmentguide.ca

ing mechanics. Meanwhile four-wheel steered machines have three possible steering modes: front wheel, all wheel and crab. The advantage of four-wheel steering is added stability.

“Because the centre of gravity is not affected by the steering of the machine, the lifting capacity is not reduced at full turn with all-wheel steer. The off-road stability of the rigid frame makes an all-wheel steer loader a versatile and profitable addition to a fleet in high-speed construction applications.”

WHAT FEATURES SHOULD CONTRACTORS CONSIDER WHEN SPEC’ING A COMPACT WHEEL LOADER?

Spec’ing equipment with the right options, and choosing the right size, will keep operators comfortable and productive and ensure your machine is suited to your job site. Features to consider include ride control, Tier 4 engine solution, hydraulic needs and more.

Quatro said the most important question to ask in choosing a wheel loader is the type of material and volume to be moved.

He recommends consulting an online material density chart.

According to Stemper, contractors and fleet managers should look at options that reduce overall downtime, including easy ground-level serviceability and non-invasive Tier 4 Final engine solutions. When right-sizing a machine for your fleet, Stemper recommends knowing the weight and density of material that needs to be moved, the size of bucket needed and the size of trucks and hoppers that will be filled. Visibility and operator comfort are also important to consider – and a bigger wheel loader isn’t always better.

Gribble agreed that operator comfort is key to consider, and noted that John Deere has taken steps to improve operator comfort including a comfortable air-ride high-back seat and the addition of ride control. A cab with heating and cooling will keep operators comfortable in all climates.

Gardner recommends considering terrain, weather and traction needs when selecting a wheel loader, and noted that differential lock is standard on all of Kubota’s wheel loaders to maximize traction. Industrial or winter tires should be utilized if needed.

“Sizing a compact wheel loader, compact track loader, skid steer, mini excavator or any machine should always come down to task>tool>machine. What are you trying to do, what is the best tool to do that task with and what host machine will power/ move that tool?” said Britton.

If you need the machine to do multiple tasks, Britton recommends sizing the machine to the primary task. Know the working envelope that you must work in and whether there are size restrictions, such as width or height, that will factor into your decision.

After assessing applications, Padgett recommends comparing bucket capacity, rated operating capacity, lift arm and bucket breakout forces. If you plan on using hydraulic attachments now or in the future, then look at auxiliary hydraulic capacity options. Operating weight is important to consider if you plan to trailer the wheel loader between job sites.

Ashton pointed out that there are several simple ways to reduce TCO of compact wheel loaders, so buying strictly based on purchase price isn’t recommended. The machine should be sized to the job and attachments and tires should be appropriate for the application. Implementing regular pressure checks will also prevent premature tire failure. Machine monitoring programs will also help owners optimize the service life of their machine. HEG

In general, the expansion of high-flow auxiliary hydraulics, advanced machine controls and available hydraulic attachments have made compact wheel loaders far more productive, versatile and easier to operate.

EARTHMOVING & EXCAVATION

NEW PERFORMANCE TIERING STRATEGY OFFERS EQUIPMENT BUYERS EASIER CHOICES JOHN DEERE INTRODUCES NEW THREE-TIER APPROACH WITH UTILITY WHEEL LOADERS

BY LEE TOOP, EDITOR

T

oday’s earthmoving equipment has a broad range of options and upgrades that can make selecting just the right machine challenging for a particular contractor.

Sometimes the job calls for a machine that’s fully kitted out with features – and sometimes you just want something that will move dirt.

That range of needs is behind a new approach to sales that John Deere has introduced, focused on certain wheel loaders in the company’s lineup. The Performance Tiering Strategy is aimed at making it easier to buy a wheel loader that will fit the buyer’s needs without extensive spec’ing and customization.

The new approach follows extensive discussion with dealers and customers, and will standardize options while continuing to offer strong service and support.

“One of the trends that we’ve seen [over the last few years] was customers needing a better expanded offering of machine solutions within the marketplace to help them stay competitive. At Deere, we’ve continued to push our machines with more features, enhanced benefits and enhanced operator comforts,” said Luke Gribble, solutions marketing manager with John Deere. “Over time, that was actually alienating some other customers that just needed machines at the lower end of the spectrum, or without some of the benefits and features.

We realized we needed to come up with a solution for that set of customers.”

At the other end of the customer spectrum, Deere was finding that customers were challenging the company to develop even more innovative and technologically advanced approach-

heavyequipmentguide.ca | APRIL 2021

es to production and efficiency on their machines.

“It was kind of neat that we have these customers that enjoy the features and benefits of the machines that we are cranking out of our factory today. We had some customers that really didn’t need all of that, and others that were pushing us to go even further,” Gribble said.

After some discussion, the Deere team developed a strategy designed to make it easier for all levels of customer to find the machines they need. The Performance Tiering Strategy offers three different tiers of equipment that are intended to meet certain sets of customer needs for different applications. Each level – the G-tier, P-tier and X-tier – will have certain benefits for certain customer needs.

The G-tier is a practically equipped, economical machine built with proven components and capabilities, Gribble described. “These are rugged and reliable pieces of machinery that are really well suited for light- to medium-duty applications. But, at the same time, these machines can still be very productive, have long-lasting components, great serviceability and operator comfort as well.”

In the middle of the range is the P-tier, which compares well to machines that are being manufactured today, Gribble said.

They have similar high-end performance capabilities, an array of features and benefits that customers in high production and high utilization applications will find useful, as well as operator comfort benefits and features to ensure uptime is managed well.

For high-end needs, the X-tier machines will bring innovation and technology to the table, Gribble said.

THE P-TIER OF JOHN DEERE UTILITY LOADERS ARE EQUIVALENT TO THE L-SERIES MACHINES.

“We’re going to put exclusive potential features in that really do push those machines to achieve higher levels of productivity and overall efficiency, and provide the ultimate customer experience,” he said.

There will be significant differences between machines from tier to tier, Gribble described, both mechanically and in technology. For example, the 644-size wheel loader is being introduced across all three tiers, but the various offerings are quite different from one to the next.

“For instance, on the 644G, customers just have the option to get differential lock in the front axle, whereas the 644P and X can get it in both the front and the rear. There are other simple things; for example, the 644G can only come with the steering wheel, and you don’t have an option to get a joystick,” Gribble explained. “There are pilot controls in the G, and EH controls in the P and X, just to name a few examples. It goes down to different bucket options, coupler and bucket compatibilities between those models.”

G-tier machines are intended to be simple and attractive from a total cost of ownership standpoint thanks to their price point, Gribble said. They’re intended for owners who might not need a machine that works every day, but when it does work it does what’s intended.

P-tier machines are essentially Deere’s L-series of machines, rebranded, he said. “They come with the same benefits and features that we brought to the market when the L-series came out. A couple of features that really come to mind are the EH controls, the redesigned cab with additional leg room and the

THE X-TIER FEATURES DEERE’S DIESEL-ELECTRIC E-DRIVE POWERTRAIN.

HVAC system, and the bucket system being redesigned for better visibility,” Gribble described.

Stepping up from the 644P to the 644X is an even greater jump – right into a different powertrain. Deere’s diesel-electric system, the E-Drive, pushes fuel efficiency and productivity forward thanks to its ability to recycle and regenerate energy into the system. The result is reduced engine loading, greater fuel efficiency and additional power to help run hydraulic pumps and brakes.

We have these customers that enjoy the features and benefits of the machines that we are cranking out of our factory today.

We had some customers that really didn’t need all of that, and others that were pushing us to go even further.

G-TIER MACHINES WILL BE FITTED WITH BASIC SYSTEMS AND EQUIPMENT TO PROVIDE A COST-EFFECTIVE SOLUTION.

“From the lower end of the G-tier to the top end of the X-tier, these are significantly different machines,” Gribble said.

All machines under the performance tiering strategy will be built with proven major components across the tiers; each machine will feature a John Deere engine, and all will be equipped with the JDLink telematics solution.

“This is going to come on all our machines. That allows our customers to really get the benefit of the whole John Deere connective support package,” he said. “That allows the customers, our dealers and us to do things like receive machine

codes, so we can go in and have the capability to perform remote diagnostics or remote programming, and keep an eye on the machine.”

Design features will be available across the board as well, with features such as easy to access maintenance points and daily service checks consistent from tier to tier.

There will be some options to select on each tier, but with certain limits. Gribble noted that at a certain point, if a customer has selected a number of options it could be more cost-effective for them to move up to the next tier.

With the new tiers coming into place on utility wheel loaders at present, the company is giving its dealer network more opportunities to attract new customers, Gribble said.

“It’s going to make our dealer channel a lot more receptive to understanding what these machines are going to do on the customer’s job site, and that allows them to grow a better relationship with the customer, get an understanding of what they’re looking for so they can steer them in the right direction,” he said. “They can be a better partner in figuring out if there’s another option, another tier, and how it can benefit their job site.”

Currently, 444 through 724 size utility loaders are available.

G-tier machines are only available in Canada at present, along with the P- and X-tier units.

More Deere machines should follow the same path in the coming years, Gribble said. “We don’t have specific timelines, but more or less over the coming years all of our major products will make the transition to this performance tiering strategy.” HEG

LIEBHERR L 556 XPOWER WHEEL LOADER

LIEBHERR

XPOWER WHEEL LOADER UPGRADES DELIVER MORE ENGINE POWER

L

iebherr has updated the performance and versatility of the L 550 XPower and L 556 XPower wheel loaders with an increase in engine performance and upgraded hydraulics.

A MORE POWERFUL ENGINE AND IMPROVED WORKING HYDRAULICS

Both the L 550 XPower and L 556 XPower wheel loaders are equipped with the power-split travel drive, installed as standard in all Liebherr XPower wheel loaders. By increasing the engine power on both models, the travel drive is even more powerful with consistently low consumption, when accelerating or penetrating into material, for example – and it’s no different when the wheel loaders are equipped with heavy protective devices or solid rubber tires for industrial operations.

An increase in performance in the working hydraulics has enabled dynamic lift and tip functions, irrespective of the size or weight of the working tool. Structural modifications to the lift arms have paved the way for higher breakout, holding and retrieval forces than before. As a result, operators are now able to efficiently manipulate challenging materials, such as logs and scrap, particularly in the upper lifting range.

FOUR LIFT ARM VERSIONS AVAILABLE

For the L 550 and L 556 XPower wheel loaders, Liebherr offers four lift arm versions in the form of z-bar kinematics and industrial kinematics, both in standard and high-lift configurations. Customers can choose which of the four versions best meets their requirements at the time of ordering. Liebherr has overhauled all four versions of the lift arms as part of the model update, as well as reinforcing the steel construction.

The modified z-bar kinematics on the L 550 and L 556 wheel loaders offers strength in the lower lifting range and higher

32

heavyequipmentguide.ca | APRIL 2021

breakout forces than before. The maximum force is produced when, for example, the bucket or attachment is working close to the ground and breaks material out of a pile. This is an important feature when picking up and loading rocks, gravel or construction debris.

Liebherr has also overhauled the industrial kinematics of both wheel loaders. The industrial kinematics is tailored to industrial operations that frequently require operators to work with heavy working tools such as light material buckets, high dump buckets and log grapplers. In addition, the industrial kinematics offers parallel guidance, which is ideal for operating forks.

The high-lift version (one for both z-bar and industrial kinematics) has extended lift arms for increased reach and more productivity during higher than average loading.

QUICK COUPLERS AND RECONFIGURED BUCKETS

The overhaul of the lift arms has increased the tip load, which means that operators of the new L 550 XPower and L 556 XPower can work with larger buckets than before, and move more material in each loading process. Liebherr has reconfigured the design of the buckets on both models, allowing customers to more accurately tailor the individual modules and wear parts of the buckets to their needs at the time of ordering.

The fully automatic LIKUFIX quick coupler system is now available for the L 550 XPower and L 556 XPower wheel loaders for the first time which will benefit operations involving multiple attachments or tools.

A hydraulic quick coupler with optimized visibility is also available when requested by the customer, as well as a range of assistance systems.

HIT THE GROUND RUNNING. The Deere 85G utilizes a reduced-tail-swing design to effortlessly maneuver through the most congested conditions. With an independent-swing boom, this versatile machine can dig near obstacles just as easily, maximizing your productivity on any jobsite. And, the redesigned cab features more space for the operator and clear sightlines, making the hard work easier than ever.

Best of all, these machines are backed by Brandt; the best-trained and most committed 24/7 after-sales support team in the business. That’s Powerful Value. Delivered.

LARGE AGGREGATES WHEEL LOADER MEETS DEMANDS FOR HIGH PRODUCTION

THE CAT 992 IS DESIGNED TO BRING POWER AND EFFICIENCY TO QUARRY OPERATIONS.

Cat’s new large wheel loader is designed to improve productivity by up to 32 percent compared to its predecessor, the 992K. Design changes help cut maintenance cost by up to 10 percent and boost efficiency.

P

opular for mining and aggregates operations, the new Cat 992 wheel loader has been designed to set new standards, with up to 32 percent more productivity, according to the company. The new loader may reduce maintenance cost by up to 10 percent and offer up to 48 percent greater payload-per-fuel efficiency compared to the previous 992K. Powered by the new Cat C32B engine with U.S. EPA Tier 4 Final/EU Stage V and Tier 2 equivalent emission engine options, the new 992 meets demand for high-production equipment with greater payloads. Powertrain design enhancements to the transmission, axles and final drive, along with the new engine, deliver a 20 percent longer interval for planned component replacement.

Offering both standard- and high-lift configurations, the 992 delivers low cost-per-ton when paired with fleets of Cat 775, 777 and 785 trucks. Standard-lift payload capacities reach 23.1 tonnes (25.5 tons) for quarry face applications and 27.2 tonnes (30 tons) for loose material handling, while high-lift capacities reach 20.4 tonnes (22.5 tons) and 24.5 tonnes (27 tons) in respective applications.

OPTIMIZED Z-BAR LINKAGE ADDS CAPACITY AND EFFICIENCY

A new Z-bar linkage optimized for performance, and improvements to rimpull and breakout force, deliver greater machine capacity and efficiency. The new 992 has demonstrated in field testing up to 48 percent greater payload-per-fuel efficiency in applications where a four-pass match to 90.7 tonne (100-ton) trucks was achieved, versus five passes with the 992K. The 992 provides up to 9.5 percent more rimpull during digging and up to 20 percent more breakout force.

The new loader features an on-demand throttle mode to optimize efficiency without slowing production. New standard automatic retarding controls disable the impeller clutch, enable the lockup clutch, and use the implement and fan pumps retarding to slow the machine on grade.

Optional New Autodig Components further improve productivity and efficiency while reducing tire wear. To stop slippage before it happens, a tire slip prevention feature reduces rimpull before the tires are set and increases rimpull when downward force is applied to the tire. The tire set function detects pile contact and automatically lifts against the pile to set the tires and increase available traction. The lift stall prevention feature automatically manages rimpull in-dig to prevent hydraulic stall while lifting through the face, so the 992 spends less time in the pile.

Optional new Payload Overload Prevention allows for productivity and efficiency improvements by providing a large enough bucket to be used to achieve target pass-match across

a range of material densities without the risk of overload. This feature can be configured to automatically stop or slow the lift function when the overload value is exceeded.

Improvements to the setback and strike plane angles, a longer bucket floor, and a stronger and larger bottom section increase the bucket fill factor by 10 percent.

Available Operator Coaching empowers operators to exceed productivity targets by measuring and providing feedback to teach proper operating techniques.

CAB REDESIGN EMPHASIZES VISIBILITY AND SAFETY

The newly redesigned cab increases visibility, offers intuitive control, and incorporates next-generation technology to boost efficiency by providing easily accessible information.

Its taller windshield increases the glass surface area by 25 pecent, resulting in 10 percent greater visibility. Operators will appreciate the cab’s 50 percent increase in legroom.

Providing shift-long operating comfort, the new 992 controls feature electrohydraulic speed-sensing steering with force feedback. Two 254-mm (10-inch) colour LED monitors display machine control and operating functions. A separate 203-mm (8-inch) screen provides a dedicated viewing feed of the standard rearview camera, upgradable with an optional 270-degree vision and object detection.

Extended major component life on the new 992 and improved service access deliver up to 10 percent lower maintenance costs. Automatic lubrication to Z-bar linkage pins with robust guarding helps to deliver more reliable operation. A front walkaround platform simplifies cleaning of cab windows. Two large openings per machine side offer quick and convenient access to the improved cooling package.

and material bridging that can lead to unwanted downtime. If uncrushable material enters the crushing process, the CSS opens twice as fast as the predecessor plant or, as an option, up to 40 times faster.

SPECTIVE, Kleemann’s user interface, is a digital operating concept that has an intuitive structure and revolutionizes plant operation with its extensive features, according to the company.

The 12-inch touch panel has been optimized with regard to user guidance and visualization. New components like a radio remote control and a small radio remote control have been integrated.

The new SPECTIVE CONNECT digital solution sends all important plant data to a smartphone.

In the new MOBICAT MC 110(i) EVO2, Kleemann has integrated a series of new technologies and improvements.

The CFS – Continuous Feed System – guarantees a continuous crusher feed and thus a daily output increase of up to 10 percent.

An independent double-deck prescreen effectively separates fines before they reach the crushing process. This increases the total plant throughput and is gentler on machines in later crushing phases.

Improved feed behaviour is guaranteed by an extra-long articulated crusher jaw, whereas a flattened transition to the crushing chamber makes an optimum material flow possible.

TIPS FOR GETTING THE MOST OUT OF ASPHALT MILLING MACHINES

BY LEE TOOP, EDITOR

A

sphalt milling has become an integral way in which roadway owners can extend the lives of their infrastructure. Stripping worn surfaces and replacing with freshly laid asphalt keeps motorists moving on smooth roads, and saves money in the long run.

For contractors, learning how to best use a milling machine is key to successful completion of paving jobs. Tom Chastain, milling product manager with Wirtgen America, offers a collection of tips and techniques that can bring more to milling machines and ensure good quality surfaces for paving.

Milling machines, Chastain said, are intended to provide the preparation for paving crews to place their best work – the better the milling operation, the better the final results.

“Our job as a milling crew is to give the paving crew a clean canvas to paint a masterpiece on,” he described. “If we mill properly, it gives the paving crew a greater likelihood of paving it correctly.”

A key starting point for good milling operations involves good communication. Milling teams need to know the job, the challenges, things to watch for and other aspects of the job – but they aren’t the only ones who need to know what’s happening.

“Obviously, we have 100 percent of the information at the office, and that trickles down to the supervisor or foreman, and then down to the milling crew. But it doesn’t stop there – we have to talk to the truck driver, for example, and inform them how we’re going to approach the job so we can do it in a safe and efficient manner,” Chastain said.

PRODUCTION THE KEY FOR MACHINE CHOICE

Milling crews keep three words in mind when they’re going to work, according to Chastain: production, production and production.

“Production is how milling crews are typically geared. The worst thing you can say to a milling crew is ‘we have asphalt on the way’ – you’ve just lit a very quick fuse,” he said. “That really sends things into overdrive.”

To be sure that production is maximized, crews need to have the right machine for the job. Chastain said that for smaller jobs, like curb reveals, joint replacement or cutting around manholes, small machines are best suited. Larger patch work may call for a compact or mid-sized machine, while full replacement work means it’s time to bring in the big boys.

Understanding the job size and requirements makes it easier to match the machine to the work needed.

MAINTAINING CUTTING TEETH KEY TO GOOD OPERATION

Milling machines are designed to do one thing: tear up the surface they run across. In the process, they also take a beating themselves, so it’s very important to be sure that maintenance is done constantly and correctly.

“If you’re in a mill and fill situation and haven’t done the maintenance on your machine and it breaks down, then everything else goes down as well – it’s a domino effect,” Chastain said. “What we’ve done with the newer machines is made it much simpler to do that maintenance, to get to the fuel filters and air filters, as well as access everything else important.

Key to the milling machine’s operation is the cutter drum and the teeth on it. “As a manufacturer, we could put two jet engines on a milling machine, but if the cutter drum is not in optimum working order it doesn’t matter – it’s not going to produce the quality or quantity we need,” Chastain described.

It’s important to review the status of the milling teeth and holders, which are wear parts and need to be replaced.

“Every time the cutting tool hits asphalt, it generates upward of 1,800 degrees F – that’s hot! When you take that along with the abrasiveness of the material and heat and that’s where you get carbide wear – it starts to break down that carbide tip,” Chastain advised.

When teeth start to wear, operators may notice white streaks on the surface behind the machine, an indication that they need to be replaced. If that’s ignored too long then the tool can be ground away and the holder starts to engage the surface.

Without a cutting edge, it bludgeons the asphalt and leaves scuff marks on the surface. Chastain described this as trying to cut a surface with an ice cream tasting spoon. At that point, both bit and holder need to be replaced – if not, the worn holder will leave the tooth at a different angle of attack compared to the rest of the tools on the drum.

One tip Chastain suggested is that if a machine is switching from job to job and the drum has a full new set of teeth installed, keep the old teeth on hand if they aren’t worn too

LARGE MACHINES LIKE THE WIRTGEN W210 FI ARE GENERALLY TASKED WITH FULL ROAD REPLACEMENTS AND OTHER BIG JOBS.

far down. That way if a tooth breaks on the new job, one of the used teeth can be installed, matching up better with the rest than a brand-new one that will cut deeper than the rest.

It’s also important to check over the water system and ensure spray nozzles are in good condition, keep the drum coolant level at manufacturers’ specs, and be sure to have spare teeth and holders – saving someone an emergency run back to the shop if there’s a problem on site. Maintain the kicker panels, which aid in removing material coming from the cutting teeth and eject it onto the conveyor belt, as well.

CONTROL SYSTEMS AID WITH EFFICIENCY

There has been quite a lot of growth in the use of grade control systems on milling machines, whether they are ultrasonics, smart cylinders, laser or other approaches. Understanding how they work is a key to achieving good surfaces.

“Ask the question: are we copying the road or profiling it?

When you copy the road, what you see is what you get – if you are referencing off the side plate sensors, yoyos or whatever, when you go over a bump it’s going to just copy the road,” Chastain noted. “Behind the paver it looks great, but when you compact it you’re just right back to where you started.”

If the road is being copied at a higher rate of speed, bumps may not be removed, and in fact more might wind up being added. Profiling can be a better approach, taking any bumps on the road and averaging them out through the use of grade control sensors.

Using a 3D scan of the road is also helpful, in that it allows crews to see the true profile of their target levels and how to deal with problems spots.

SLOW DOWN FOR SMOOTHER CUTS

The best milled surfaces are developed from slower speeds, Chastain noted, but production in feet per minute should be balanced based on the end results and the size of material desired from any particular cut.

“The slower the machine’s forward motion is, the more hits those teeth are going to make, and the smaller the material,”

THE CUTTING DRUM IS KEY TO SUCCESSFUL MILLING. IT AND THE CUTTING TEETH MUST BE MAINTAINED PROPERLY.

Our job as a milling crew is to give the paving crew a clean canvas to paint a masterpiece on. If we mill properly, it gives the paving crew a greater likelihood of paving it correctly.

Tom Chastain Milling Product Manager he advised. “Milling faster doesn’t change the line spacing, it changes the quality of the pattern being left behind. When there’s a bigger swipe being taken, the pattern is more coarse.”

Even for production-minded milling crews with high-horsepower machines, higher speeds are not the best. “At those kinds of speeds you’re just excavating material, not milling – you may have to add a crushing and screening aspect to the whole process,” he said.

Be sure to start slower, as well – when the machine engages in the cut and begins to move, give the tracks time to get in and the hydraulics enough time to react. Starting out too quickly can cause the machine to drop too hard and potentially leave a brand-new dip in the road.

All in all, Chastain said, the keys to good milling come down to a few key points.

“If we maintain our machine, we have bettered our chance to achieve quality. If we slow our feet per minute down, we have bettered our chance to achieve quality. If we communicate with our team regarding the job, we have bettered our chances to achieve quality,” he said. “If we do all of these things while putting safety first, we will achieve quality.” HEG APRIL 2021 | heavyequipmentguide.ca

olvo Construction Equipment has expanded its Compact Assist for asphalt compactors with the launch of a new entry-level package, adding Compact Assist Start as an introductory intelligent compaction offering.

Whether it’s for mapping the road, estimating density or producing job site reports, Compact Assist is now available in three packages to match customer requirements. Each package provides varying degrees of access to the core functions of pass mapping, temperature mapping and density/ stiffness mapping. All three packages are powered by the Volvo Co-Pilot, a 10inch in-cab tablet.

Compact Assist Start helps customers take the first step into Intelligent Compaction. Easy to use and with no setup required, the entry-level package includes pass mapping and temperature mapping functionalities, providing the operator with real-time data about how the job is progressing.

Pass mapping gives operators a clear on-screen view of the roller’s coverage of the asphalt, highlighting stop points and overlaps so adjustments can be

42

heavyequipmentguide.ca | APRIL 2021

made quickly and efficiently without missing a spot.

Temperature mapping ensures that compaction is completed at the optimum pavement temperature. A

colour-coded map of surface temperatures and the ability to set the maximum/minimum range enables the operator to easily avoid rolling with a mix temperature that is too hot or too cold.

Compact Assist Start is available on Volvo DD110C, DD120C, DD128C and DD140C asphalt compactors.

Upgrading to the other two Compact Assist programs is easy, and Compact Assist Start comes with all of the wiring and most of the needed hardware. The next package level is Compact Assist, ideal for customers looking to record and track data across a job site. It provides greater accuracy and reporting opportunities through the addition of a high-accuracy GPS antenna, recorded and saved job data, automatic job report creation with USB and over-the-air download.

TRACK CONVERSIONS KEEP OPERATIONS TRUCKING IN DIFFICULT CONDITIONS EASY-TO-INSTALL POLYURETHANE TRACK SYSTEMS RUN ON TRUCKS OF ALL SIZES

BY LEE TOOP, EDITOR

W

hen construction sites move off the road and into challenging conditions, it’s often the trucks that serve on those sites that are the most affected.

Environmental requirements to reduce damage on wet, marshy sites, in snowy conditions or a number of other manners mean that trucks on tires are limited in where they can go.

If it’s impractical to build haul roads or other ways to get those trucks from point to point, one option may be to look at track conversions. Developed initially for smaller vehicles, easy-to-install tracks for wheeled trucks are growing in popularity.

Edmonton, Alberta-based Right Track Systems developed its track systems for small vehicles such as ATVs, UTVs and skid steers, around 15 years ago, according to General Manager Tom Zaleski. It was the oil and gas industry that moved their designs toward trucks.

“A few years back, oil companies came to us and said that when they’re servicing sites, or out on the patch, they run into really difficult ground conditions – mud, sand, snow and all that, which makes servicing rigs really difficult,” Zaleski said.

Initial designs of rubber tracks for larger units were developed based on the smaller vehicle systems and scaled up to fit over the tires of large service rigs used in the oil patch, offering greater flotation for vehicles having to deal with those softer surfaces.

“The guys in Fort McMurray and elsewhere would use these to run up and down the cut lines, to service their wells, and in those kinds of situations. They found it provided a great reduction in ground pressure, a lower environmental footprint, and

44

heavyequipmentguide.ca | APRIL 2021

increased their traction,” Zaleski described. “Instead of having to hire big Cat machines or helicopters to come out and drag their units out of the sand and snow, they could just outfit their own units with tracks and traverse that difficult terrain.”

Once track conversions had begun making their way through the oil industry, other sectors started to look at the technology.

Many businesses work in sloppy conditions and need to find ways to move their trucks through mud and other wet ground, and the utility sector, construction companies and agriculture operations started showing interest.

Zaleski said the approach taken by Right Track is a simple one: a rubber track is simply wrapped around the tires, tightened and put to use on the site. While there are some undercarriage systems that switch out the entire tire system with a sprocket-driven unit, those are quite cost-prohibitive in most cases. Rubber tracks are easier to use and maintain, he noted.

The design has gone through several iterations over the years to find the best capability possible for weight and speed, especially considering that the tracks will be likely to face a broad range of conditions.

“Guys don't necessarily want to put the tracks on and just stay in the soft stuff – they want to traverse the site and go several miles,” Zaleski said. “They want to be able to do that quickly and efficiently while having a track to hold up to that speed and weight.”

Tracks can be installed on a broad range of popular trucks in the construction sector. They are available for everything from smaller vehicles up through tandem and tri-axle vehicles all the

CUSTOM TRACKS CAN GIVE TRUCKS AND TRAILERS ADDITIONAL GRIP AND FLOTATION IN CHALLENGING GROUND CONDITIONS.

way up to large mining trucks, Zaleski noted.

“The standard in the truck and trailer industry is generally tandem axle trucks running 11R22 or 24/25 dual tires on a tandem axle, running roughly a 15- to 20-ton load,” he said.

Different uses require different types of track, which can handle a range of weight and ground conditions. Right Track’s versions start with a standard track that can handle loads of up to 30 tons at travel speeds of 30 to 35 mph, Zaleski explained.

The company’s Off Road Construction (ORC) tracks are used on larger vehicles like articulated dump trucks or mining vehicles, and can handle the same speeds but carry up to 80 ton weights.

CUSTOMIZATION INCREASES USE OF TRACKS

Track systems are customized for each buyer’s equipment, Zaleski said, to ensure a precise fit. “We send out a sizing schematic that customers fill out with the dimensions of their current unit and so that they can check their clearances – you need extra space to run these tracks,” he said. “We have ways of getting around it if they have a clearance issue. . .99 percent of the time tracks will go on without modifications.”

Other features can also be customized, such as the style of cleats used.

“If guys are running up and down ice roads, we can install steel cleats to give them more traction that also helps reduce wear on the outside tread. This is good for people working in mining conditions, because they’re in a lot of rock that can be quite abrasive to polyurethane tread,” Zaleski. “In other cases, we can go to a lower profile polyurethane; customers order

TRACK SYSTEMS ARE AVAILABLE FOR USE ON AERIAL LIFT EQUIPMENT AND TELEHANDLERS AMONG OTHER TYPES OF MACHINES.

that when their biggest concern is environmental damage and they want to leave as little a trace of the truck going back and forth as possible.”

When the tracks arrive at a customer’s operation, they should fit on that specific truck perfectly and can also be used on similar vehicles, with extension or shortening kits available to help add versatility.

On a tandem truck, installation generally takes a half-hour to 45 minutes per side. The tracks are laid out flat, the truck driven onto the midpoint, and air let out of the tires. Customers use a winch or comealong to draw the tracks together at a hinge point, where they are connected with a pin. Tires are refilled, and the truck is able to get to work. Removing the tracks just takes pounding out the pin and rolling the tracks off.

Right Track units are built with replaceable cleats or grousers, depending on the needs of the customer. When the cleats are worn, customers can order new ones for around a third of the price of new tracks.

Along with trucks and trailers, track conversions have become available for a range of other products. Aerial lifts and telehandlers are one more recent area that Right Track has added to its track conversions, though in those cases installation involves removing the tire and installing a foam-filled tire and rim structure with a track around it, Zaleski said.

Popularity of truck track conversions has grown steadily, and today Right Track is selling into countries around the world, according to Zaleski. Most are still in the U.S. and Canada, but others have sold into Europe, Australia, Africa and China. HEG APRIL 2021 | heavyequipmentguide.ca

than 2,000 times per second. Based on the collected data, the system provides variable steering effort through its electric motor, applying additional torque as needed to make it easier to keep the truck on the desired route.

Along with a significant reduction in driver steering efforts at slow speeds, Command Steer suppresses uneven terrain, such as potholes, dips and ruts. The system reacts to those irregularities by countering the steer force, smoothing the steering feedback and reducing steering wheel “kicks.”

“Drivers no longer need to fight the wheel when driving on severe terrain or during difficult weather conditions requiring a lot of steer effort,” Wrinkle said. “Mack Command Steer helps the driver maintain greater control of both on-highway and offroad applications at low speeds and high speeds.”

An additional benefit of Mack Command Steer is that the system features a unique return-to-zero capability that automatically returns the steering wheel to the centre position in forward and reverse, helping to simplify tight maneuvers.

HOW TO CHOOSE A CONCRETE PULVERIZER

BY KAITLYN TILL, EDITOR IN CHIEF

D

estroying concrete is tough business. Concrete pulverizers can take care of primary demolition, chewing apart a building or wall, or destroy reinforced concrete at ground level, but what do you need to know before choosing a concrete pulverizer for demolition? I spoke with Crystal Sanders, HAT – Account Manager, Western & Mid-Western Canada, from Epiroc Canada to get the scoop on types of concrete pulverizers and what you need to know to choose the right concrete pulverizer for primary or secondary concrete demolition applications.

WHAT ARE THE FEATURES AND TYPES OF CONCRETE PULVERIZERS?

Sanders noted that Epiroc offers four different work tool types that can do pulverizing: demolition pulverizers, bulk pulverizers, combi cutters and concrete busters with options for machines ranging from 2 to 85 tons. The combi cutter multi tool comes with a pulverizing jaw; it can also be outfitted with a shear jaw or a cutting jaw. Concrete buster attachments are designed for very thick concrete walls or structures or when the operator has limited visibility.

DP demolition concrete pulverizer attachments for excavators are primary pulverizers for reaching up to grab the side of a concrete wall or structure to chew on it and tear it down.

These pulverizers can further reduce rubble on the ground.

BP bulk concrete pulverizer attachments for excavators have an angled jaw which allows you to pulverize concrete that is already on the ground in a secondary pulverizing application, or for primary demolition at ground level or below grade.

The angled shape of the BP pulverizers allows the operator to change the angle of material more easily and provides greater flexibility for reducing reinforced material at ground level. If you have concrete slabs on the ground, the angled jaw can slide underneath and start chewing.

These two types of pulverizers have different tooth designs and pulverizing angles, but both crush concrete and rebar between one fixed and one moving jaw and tear through rebar with a blade in the throat.

WHAT YOU NEED TO KNOW ABOUT THE JOB SITE AND MATERIALS FOR DEMOLITION OR REDUCTION

You will need to know some general information about the application – what is the material, what is the hardness of the material, where is the material located, and how thick is it?

Size, thickness and presence of plate or rebar is also important to know when selecting a concrete pulverizer.

Whether the demolition needs to be done at height or below grade, as well as job site conditions, are other factors. Will the work be done in water, or will you be close to other buildings?

Are you in a residential area?

EPIROC DP 2800 CONCRETE PULVERIZER

WHAT YOU NEED TO KNOW ABOUT YOUR EXCAVATOR WHEN CHOOSING A CONCRETE PULVERIZER

Epiroc Canada works through dealer partners to assess the right attachment for a customer. Once the customer’s application and materials for demolition or reduction are established through the dealer, Epiroc Canada can then assess the equipment that the contractor has available and make an attachment recommendation.

Key factors include excavator weight, hydraulic requirements and the capacity for that machine to run the attachment and carry the load. Most of that is usually identified with the dealer technician that sets up the attachment on the machine. Sometimes secondary hydraulics have to be added to excavators. For example, many demolition attachments have 360-degree power rotation that requires secondary hydraulics to operate both the rotate and open and close functions.

MAINTENANCE NEEDS OF CONCRETE PULVERIZERS

Concrete pulverizers require high-quality grease on every shift, and beyond that maintenance depends on utilization and the materials that the attachment is used for. Wear parts on a concrete pulverizer are replaceable. The small blade in the throat of the attachment behind the tooth plate, which cuts through rebar-reinforced concrete, is reversible and replaceable, and jaw teeth can be replaced as needed.

The MHP mobile hydraulic pulverizers offer peak efficiency for secondary demolition and concrete recycling applications. These attachments offer excellent power-to-weight ratio and large jaw capacities and the new design is optimized to pick up, crush and separate rebar from concrete faster than ever before as a result of high-tip forces, increased jaw sizes, and fast cycle times.

The MHP’s unique shape makes it extremely versatile for use on the ground when separating rebar from concrete in recycling applications. Key features of the new MHP include: reverse cylinder with internal hydraulic lines, pass through lower jaw that facilitates excellent rebar separation, interchangeable teeth offer lower maintenance, serrated blades for efficient rebar cutting, and bucket-style teeth for sorting of materials.

New pulverizer jaws for the CC3100 offer more applications with one cutter body. The utilization of the cutter is increased and rounds off the needs on smaller job sites.

Epiroc’s Coupling and Positioning System (CAPS) makes it easy to switch between the jaw types on site to suit the work at hand. The full jaw range consists of Universal (U) jaws, Steel Cutting (S) jaws and Pulverizer (P) jaws. The CC3100P boosts productivity by utilizing two powerful hydraulic cylinders with integrated speed valves to minimize cycle times and reduce fuel consumption. The hydraulic drive provides 360-degree endless rotation, which bolsters handling precision and allows for optimal positioning during demolitions.

LAST WORD

LAST WORD ASPHALT MIX PERFORMANCE TESTING: A PATH FORWARD FOR PAVING IN ONTARIO

BY DR. DOUBRA C. AMBAIOWEI

I

t is a known fact that higher quality of any product has a positive impact on its performance. However, it is also important to stress that satisfying the quest for quality isn’t particularly cheap. To minimize or eliminate any negative cost(s) associated with the quality of any product, emphasis is placed on getting it exactly right the first time. Herein lies the challenge within the asphalt and/or roadbuilding industry, not only in Ontario, but the world-over.

The desire amongst stakeholders (owners and contractors) to construct smooth and long-lasting asphalt pavements that are cost-effective often seeks to answer the question of “durability” amongst other factors. In order to increase the durability of an asphalt pavement, the mix design, and production of the asphalt MUST ensure that the end product can resist factors such as age hardening of the asphalt cement, disintegration of the aggregate and stripping of the asphalt film from the aggregates, and ultimately rutting and cracking of the pavement.

These, coupled with placement best practices during new construction, rehabilitation and/or maintenance of the pavement structure, ensure that the desired quality and material properties such as impermeability, strength, stability, stiffness, flexibility, fatigue resistance, and workability are maintained for long-term performance. Within these contexts the asphalt paving industry in Ontario is keen on finding and implementing end-product performance measurements for Hot Mix Asphalt (HMA).

However, there are challenges and concerns surrounding a number of issues such as: (1) how to best to measure and/or evaluate properties of the mix; (2) properties of the constructed pavement to meet specification requirements; (3) how performance specifications will be implemented; (4) effect on current mixes; (5) cost; (6) production and (7) constructability. These challenges remain areas for continuing dialogue, education and research.

At this time, the Ontario Ministry of Transportation (MTO) has identified three test methods as the three most promising approaches for performance testing in Ontario. They are as follows: (A) the Illinois Flexibility Index Test (IFIT) using the “Semi-Circular Bend (SCB) test – reflecting performance at intermediate temperatures; (B) the Hamburg Wheel Tracking (HWT) test – reflecting performance at high temperatures; and (C) the Diskshaped Compact Tension (DCT) test – reflecting performance at low temperatures.”

Since selecting these tests, the MTO have been engaging in post-production testing and evaluation of samples taken from actual projects towards developing Quality Assurance (QA) acceptance criteria. Further to these efforts, the Ontario Asphalt Pavement Council (OAPC – Council of Ontario Road Builders’

50

heavyequipmentguide.ca | APRIL 2021

Association (ORBA)) has been encouraging the Ministry to include “information-only testing” in future contracts to help drive industry’s knowledge and the potential investments in associated new testing techniques and testing equipment.

In addition, the Council, through its recently formed Ontario Asphalt Expert Task Group (OAETG), is pursuing a 5-year vision focused on three main goals: (1) “Bridging the gap in knowledge in mix performance testing and acceptance;” (2) “Executing an industry exchange program on engineered mix designs/balanced mix designs;” and (3) “Field evaluations and specification adjustments.” The OAETG believes these initiatives will assist industry toward a better understanding of failure challenges, pin pointing failure points, the associated engineering material parameters, and how implementable approaches can best balance risks, ensure quality and safety, and save costs for the stakeholders.

Implementing performance testing in Ontario could be the next major step to ensuring reliability and fast-tracking innovation in mix design and construction practice given the variabilities associated with materials, traffic and the ever-changing climatic conditions. It may also be the opportunity to switch the province completely from the older Marshall mix technology to Superpave, since controlling volumetric properties alone is not sufficient to ensure good performance.

As part of its core mandate, the Ontario Asphalt Pavement Council recognizes and fully supports the need to continually improve and enhance the quality and performance of asphalt pavements in Ontario. OAPC offers a number of publications including their ABC series, factsheets, informational brochures and bulletins all available on its website, www.onasphalt.org, including educational seminars and other training programs delivered throughout the year.

DR. DOUBRA AMBAIOWEI is a Professional Engineer in the Province of Ontario, and Technical Director, for Ontario Road Builders’ Association and Ontario Asphalt Pavement Council (OAPC-council of ORBA). He has developed extensive and practical experience in asphalt research and technical studies, and pavement engineering consulting services. His work specifically supports all technical requirements to promote the quality use of hot mix asphalt, and all other roadbuilding materials and construction best practices in general.
