What You Should Know About the ASPHALT Industry in 2019 FHWA photo

Another innovation within the industry involves The Asphalt Institute’s move to ally with the Federal Highway Administration (FWHA) in studying and implementing the use of a Intelligent Compaction (IC for short).

By Jennifer McKevitt CEG CORRESPONDENT

What’s new in the world of asphalt and paving?

Construction Equipment Guide (CEG) spoke with Brett Williams, director of engineering & technical support of the National Asphalt Pavement Association (NAPA) to find out what’s on the horizon for the industry.

First off, equipment needs are changing to meet market demand, Williams said.

“New technologies and innovations — in equipment, as well as materials and mix design — are important to the future of our pavements,” Williams said. “They help us ensure quality and consistency, improve performance, and control costs.

It’s also important to recognize that it’s not just equipment that’s changing … our construction practices and workforce needs are changing, too.

“Our country’s youth are growing up in a connected world where technology impacts nearly every aspect of their lives,” he continued. “Construction equipment is increasingly incorporating sophisticated technology that requires a higher level of familiarity with computerized systems to best use and maintain than was the case in the past. In addition, these technologies are now being paired with simulators that allow for life-like training tools that can bring future workers up to speed quickly and economically. As equipment operation continues to progress toward something more similar to playing a video game, there will be a familiarity and comfort for the next generation of workers.”

According to the Association of Equipment Manufacturers’ (AEM) ConExpo/Con-AGG website, asphalt innovations in 2018 also included those by Minnesota-based MnROAD, which recently began collaborating with the National Center for Asphalt Technology (NCAT) to share research results on experiments conducted on roadway construction materials in various traffic con-

Alaska DOT Jumps Into Action Hours After Earthquake Destroys Major Roadways Lori Tobias

CEG CORRESPONDENT

The first sign of trouble was the sound. Very loud.

Like a low flying 747, recalled Shannon McCarthy, administration operations manager of the Alaska Department of Transportation. Then came the jolt and McCarthy knew this was no low flying plane.

It was the beginning of magnitude 7.0 earthquake that would shake southcentral Alaska for 18 to 35 seconds and trigger aftershocks for weeks after.

On that morning of Nov. 30, McCarthy was on her way to a meeting with a reporter at the DOT

Work included the repair of eight major breaks in area roadways, many highly trafficked.

Despite the challenges, not the least of which included at least two sinkholes on a major highway due ongoing aftershocks, contractors finished all the major breaks but one within 72 hours. The last took an extra 12 hours.

Anchorage maintenance facility to discuss the challenges the agency is facing with winter road conditions as the climate warms. She had just stepped from her car when the shaking began. It was 8:29 a.m.

“I noted I was on asphalt and I was concerned because I didn’t know what the soil was like underneath,” she said. “I moved over to concrete, but that made me closer to the building and I didn’t want to

The most critical component of repairs was asphalt, but contractors had shut down their asphalt plants for the winter at least a month or more before.

be hit by anything falling. I went inside and of course, everyone was under their desks and I said, ‘Wow this is some shaker we’re having.’”

McCarthy joined her colleagues under the desk until the shaking stopped, but almost immediately the aftershocks started.

“I knew that we had damage pretty quickly because the reports started coming in,” she said.

“Then we just sort of went to work.”

That work included the repair of eight major breaks in area roadways, many highly trafficked. But the DOT was not caught unprepared, a factor that allowed the state to repair roads in record time.

“We had been planning for something like this for some time,” McCarthy said. “Four years earlier on the anniversary of the 1964 quake, we did some see EARTHQUAKE page 6

The DOT was not caught unprepared, a factor that allowed the state to repair roads in record time.

“The one advantage is because these were breaks in the road and people had to attend to things at home, we had a very patient public,” McCarthy said. “They understood we had the road completely shut down and we don’t normally do that.”

EARTHQUAKE from page 4 drills. More recently, we had an incident where an oversized truck hit one of our bridges on our main route on the Glenn Highway between Anchorage and the Mat Su. (Matanuska-Susitna Valley). It shut down traffic pretty significantly. We didn’t have a lot of alternatives. It really slowed down the commute.

What we did after that is we revisited the tabletop plans.

“As contractors called in, we would assign them with project engineer to a site. We would ask what is your capability? A lot are shut down for the winter.

The one thing that is truly amazing is we literally had contractors assigned to the site within two hours of the event.”

The challenges were many. The temperature was mild for the area — 30 to 40 degrees — but the

“I knew that we had damage pretty quickly because the reports started coming in,” Shannon McCarthy said. “Then we just sort of went to work.”

“As contractors called in, we would assign them with project engineer to a site. We would ask what is your capability? A lot are shut down for the winter. The one thing that is truly amazing is we literally had contractors assigned to the site within two hours of the event,” Shannon McCarthy said.

ground was frozen, freezing rain falling and daylight in short supply. More importantly, the most critical component of repairs was asphalt, but contractors had shut down their asphalt plants for the winter at least a month or more before.

“The morning of the quake, we started the conversation. We said, ‘We’re going to need asphalt in four or five days; how fast can you get your plant running?’ The contractors checked on their own buildings and then ran out and checked on asphalt plants and ran out and turned every one on. It usually takes 10 days to get everything running. It was the ability to get these plants up and running that allowed us to make these repairs in record time.”

The DOT also took extra steps to make sure the asphalt — which is hard to compact before it cools and hardens in cold weather — could be compacted sufficiently to hold. They heated the oil extra hot and kept the asphalt trucks stacked up so they could pave continuously. They also used extra-wide/heavy rollers, as well.

Despite the challenges, not the least of which included at least two sinkholes on a major highway due to ongoing aftershocks, contractors finished all the major breaks but one within 72 hours. The last took an extra 12 hours.

“The one advantage is because these were breaks in the road and people had to attend to things at home, we had a very patient public,” McCarthy said. “They understood we had the road see EARTHQUAKE page 27

Roadtec The RP-195e and the SB2500 were recently used for a paving job at the Dallas Fort Worth International Airport.

Stop by Booth 23089 at World of Asphalt where Roadtec will be showcasing five asphalt paving machines, including two pavers, a cold planer, a stabilizer and the Shuttle Buggy MTV. All Roadtec machines are built from A656 Grade 80 steel, which is twice as strong as the mild steel commonly used.

This yields a stronger, lighter frame.

The newest model of Roadtec’s RX-700e cold planer features the increased power of an 800 hp Tier IV Final Caterpillar engine. The new Tier IV Final engine does not require DEF fluid as a component of the after-treatment system, reducing the operation costs typically required at this emission standard. The updated half-lane cold planer provides even higher production and reliability through increased power and efficient design.

Kyle Hammon, product manager, mills, stabilizers, brooms, said, “The increased horsepower delivers even more production without sacrificing. We give customers what they need — a reliable and efficient cold planer that helps them complete jobs on time and with success.”

The SB-2500e Shuttle Buggy MTV will be in the booth also. With 25 tons of struck capacity in the main hopper, the Shuttle Buggy acts as an onsite silo, enabling nonstop paving while remixing HMA

for the best possible mat. The Shuttle Buggy offers superior material handling.

Two Roadtec pavers, the RP-170e rubber tired paver and the RP-195e rubber-tracked paver will be in the Roadtec booth. The RP-170e is an 8 ft. asphalt paver with a compact wheelbase for greater maneuverability without sacrificed performance. The RP170e can achieve a 30 in. turning radius, with the standard steering assist engaged, which is helpful for managing tight spots around barriers. The RP195e paver features Roadtec’s anti-segregation design and hydraulic swing-out operator stations giving a side view of the machine.

The RP-195e and the SB2500 were recently used for a paving job at the Dallas Fort Worth International Airport. The Roadtec machines were chosen for their reliability and durability on the allimportant Runway 17. Built in 1984, Runway 17Center/35-Center handles more arrivals than any other runway at DFW. Khaled Naja, executive vice president of infrastructure and development at DFW Airport, said in statement, “This runway work is a critical need for DFW Airport, and the first major step in our ten-year plan to modernize infrastructure across the Airport.”

SX-8E soil stabilizer-reclaimer is Roadtec’s largest

soil stabilizer and also will be on display at World of Asphalt. With an operating weight of 82,000 lbs., the SX-8 is capable of cutting up to 20 in. deep and 100 in. wide and is designed for road rehabilitation, cold recycling, or soil stabilization. With weight balanced over the cutter, the machine is designed to handle the most challenging surface and ground conditions.

World of Asphalt Booth 23089 also is the place to see Roadtec’s Guardian Telematics System, a twoway telematics system. Most recently, Guardian was enhanced to provide increased functionality, faster speeds, and better maneuverability. Guardian continues to deliver best in class fleet management through real time reporting via a cellular signal, which saves customers time and money.

While some Telematics systems simply report GPS location or simply send fault codes, Guardian reports real time, detailed data and allows two-way communication via cellular communication. This enables the data to be closely monitored in realtime and allows owners and service technicians to closely monitor data about electrical and hydraulic systems, grade/slope control, engine performance, fuel consumption, and more.

Wirtgen Wirtgen’s W 150 CF/W 150 CFi can now also be equipped with a 70.8 in. (1,800-mm) milling drum assembly enabling customers to profit from a wider range of applications. The most powerful machine in the compact milling machine class with its 298-kW engine power, it now achieves even greater productivity and area output, according to the manufacturer.

Wide Range of Working Widths for Maximum Cost-Efficiency The W 150 CF/W 150 CFi can tackle a wide array of different jobs, ranging from classic small milling machine applications such as partial road surface repairs to the removal of entire road pavements. The milling machine is therefore especially suitable for large-scale projects in confined spaces such as on urban job sites. Particularly in such conditions, the sophisticated visibility concept combined with the camera systems help the machine operator to maneuver the milling machine.

With the flexible cutter system, users can switch between milling drums with different working widths of 23.6, 35.4, 47.2 and 59 in.

(600, 900, 1,200 and 1,500 mm) simply and very quickly. In addition, with the 59 in. working width it is possible to switch to milling drums with different tool spacings.

A new extension kit is now also available which extends the milling drum housing by 11.8 in.

(300 mm). With this kit, the W 150 CF/W 150 CFi has a working width of 70.8 in., making it even more versatile and also ideal for surface course rehabilitation on medium to large job sites, according to the manufacturer.

Efficient RAP Loading Alongside milling and cutting technology, loading conveyor construction is another of Wirtgen’s core competencies. To ensure efficient direct loading of the milled material onto trucks, the loading conveyor system of the milling machines has a high loading capacity. A larger cleat profile on the discharge conveyor of the W

High productivity, versatile and economical operation as well as simple transport make the Wirtgen W 150 CF/W 150 CFi compact milling machine with the new 70.8 in. (1,800 mm) milling drum assembly the ideal machine for surface course rehabilitation on medium to large job sites.

150 CF/W 150 CFi guarantees optimum material transport and, with the higher conveyor speed, precise loading is also very fast. Another advantage is the extremely large conveyor slewing angle of 60 degrees to the left and the right, which also enables milled material to be loaded under difficult site conditions such as on traffic circles or crossings.

Fast Site-to-Site Transfer Due to Simple Transportation To maximize the cost-effectiveness of milling operations, cold milling machines need to be

transported quickly from one site to the next. This is especially true when the machines are as versatile in various applications as the W 150 CF/W 150 CFi. Wirtgen’s top performer therefore has an optimized machine transport weight despite its tremendous engine power.

Meanwhile, preparing the machine for transport is a time-saving process, since the hydraulically operated folding conveyor can be folded quickly. These features ensure that the high-performance milling machine is ready for action again in next to no time.

Calvin Group shuttle buggies, reclaimers, chip spreaders, distributors or stabilizers often look to Calvin Group for help, not only because of its inventory, but because of its business philosophy.

“Our reputation is more important than selling a piece of equipment,” Pentz said. “We’ve been very blessed to be able to have the relationships we do with our customers.”

So far that philosophy has worked out well for Calvin Group, and its reputation for honesty and integrity has spread internationally with the name Calvin Group synonymous with quality used commercial paving equipment.

That philosophy permeates Pentz’s family and the company, which his sons Michael and Matthew are both involved with full time. Michael, who is responsible for marketing and day-to-day details as well as sales, has been with the

Mark Pentz, president of Calvin Group Inc., remembers telling his father, “I’m gonna’ sell big iron when I grow up.” His father would adamantly reply, “No, you’re not. You are going to get a professional job.” But that never stopped Pentz.

After selling “big iron” for more than 30 years, he still has the same enthusiasm for the industry as when he was a kid.

Growing up in central Pennsylvania, Pentz was in the business from a young age. His father, Marlin, ran a Blaw Knox, Case and Dynapac dealership. One of Mark’s first jobs was sweeping floors there.

“I was a kid sweeping floors and doing every mundane job you could do in a dealership, but I grew attached to the equipment,” Pentz said. “Especially the road widener at that young age, probably because of its simple design.”

He tried the “professional route” just out of college, and he didn’t enjoy it.

(L-R) are Mark, Marlin, Matt and Michael Pentz.

company more than a decade. Matthew more recently joined after working in sales at Ritchie Bros.

“We aren’t here to compete with anyone else. We are here to augment everyone’s business,” Michael said. “We honestly don’t look at other folks that sell paving equipment as competitors. We try to be an asset to everyone in the industry. Auction companies may call us for values, dealers call us to help with a piece that has been challenging to sell. Our goal is to do business with our customers and contacts for the long term. It’s never just a one-shot deal for us. This is critical to who we are.”

To learn more about Calvin Group Inc., call Mark at 970/214-9888 or visit www.calvingroupinc.com.

Calvin Group will be in booth 23137 at World of Asphalt.

That early passion for paving equipment never faded. It’s a familiar story in the industry and that passion is still front and center. Just ask him. He loves the thrill of finding equipment and building new relationships.

“There is just something about a road widener,” he said with a grin.

That’s also one of the reasons Pentz gives when asked why his company sells only paving equipment.

After a decade selling dirt equipment, Pentz returned to his roots and started his own company, Calvin Group Inc., in 1996 with a focus on used commercial paving equipment, like the road widener. The company has broadened its market from its early days in Ohio and Pennsylvania to a national and even global focus, serving customers in North America, Europe and Australia.

This is a clear benefit to contractors.

Williams noted further progress in asphalt and paving are already in place.

“Advances in automation and technology are coming to market regularly,” he said. “The targets for these advances can vary from improved efficiency, increased observance of quality measures, assurance of best construction practices, operation monitoring and maintenance scheduling, and more. This trend is consistent with the asphalt pavement industry’s quest for continuous quality improvement and providing customers with most economical and highest performing pavement.”

In fact, Williams has his own ideas about what he’d most like to see develop in the world of asphalt and paving.

“I believe that the next large advancement in the asphalt and pavement equipment world will be increasing communication among pieces of equipment and then getting that information dashboarded and in front of the people building and managing the construction of our infrastructure. We'll also be able to mine that data to continuously improve our quality, practices and performance.”

In other words, an increase in the availability of smart machines that both speak with and cooperate with each other, in order to improve the asphalt and paving processes currently in place, is sought. Machines that can adapt to temperature changes, offer advice on best paving strategies, and suggest and implement improvements where and when needed.

Augmented reality, or virtual reality devices, are just part of the picture.

Accordingly, equipment makers regularly seek input from those in the field, regarding desired upgrades or changes to design.

“NAPA counts among its associate members many of the leading equipment manufacturers,” Williams said. “Working with NAPA’s engineering committees and task groups, as well as through the NAPA Associate Members Council, these companies are active partners within the asphalt pavement industry, working to better understand the challenges faced

“The asphalt pavement industry — and the construction industry in general — is ripe with opportunities for innovation. And we are already seeing many advances that are being incorporated into equipment and fleets. It is quite exciting and points to a bright future,” said Brett Williams, director of engineering & technical support of the National Asphalt Pavement Association (NAPA).

SCREEN MACHINE Simply due to its three significantly larger 5 by 20 ft.

(1.5 by 6 m) screen boxes, users can expect even greater yields with the 520TS3.

Screening is all about uptime, productivity and tons per hour (TPH). Not surprisingly then, those demands were the entire motivation in creating the new Spyder 520TS3 screening plant from Screen Machine.

“We already have a screening plant — the Spyder 514TS3 — that has taken screening productivity to a new level since its introduction three years ago,” said Matt Brinkman, director of engineering at Screen Machine.

“We saw an opportunity in creating the Spyder 520TS3 to refine and build upon what we learned through extensive testing with the 514TS3.”

The 514TS3 has been a workhorse since its introduction in 2015, with ag producers raving about its productivity and dependability, according to the manufacturer.

Simply due to its three significantly larger 5 by 20 ft. (1.5 by 6 m) screen boxes, they can expect even greater yields with the 520TS3. But that’s only part of the story. The 520TS3 has a number of other unique features that are only available on Screen Machine Spyder Plants, including SmoothStart technology, which eliminates harsh vibration on start-up and shut-down. It can produce four products at once via the front fines conveyor, the right overs conveyor and the left large mids and small mids conveyers.

The 520TS3 also can be paired with these Screen Machine crushers as a recirculating plant: 4043T impact crusher, JHT and JXT jaw crushers and CXT cone crusher.

Spyder 520TS3 specifications include: • Engine: 110 hp C4.4 Caterpillar Tier IV • Screen Box: 2 Bearing • Screen Angle: Adjustable; 18, 21, 24 and 27 degree • Top Deck: 5 by 20 ft. side tension • Middle Deck: 5 by 20 ft. side tension • Bottom Deck: 5 by 20 ft. end tension • Feed Height: 8 ft. 4 in. without Grizzly • Feed Width: 16 ft. with Grizzly; 14 ft. 10 in. without Grizzly • Hopper: 9-yd.

In addition to sharing more information about its newest Spyder screening plant at World of Asphalt/AGG1, Screen Machine also has a 4043TR recirculating impact crusher on display.

The 4043TR is one of the best-selling recirculator units in the industry, due to its high-volume productivity and superior dependability. Built on the heritage of the original Screen Machine 4043T impact crusher, the 4043TR provides dual 5 ft. by 12 ft. shaker decks in front for complete crushing and screening from a single unit. Meanwhile a recirculating conveyor ensures continuous productivity. And, the crusher relief system of the 4043TR practically eliminates downtime due to over-feeding, according to the manufacturer.

It is available with a choice of Cat or Volvo Tier IV engines.

Lake Erie Portable Screeners designs, engineers and manufacturers its flagship Pitbull 2300, Pitbull 2300B, Pitbull 2300P, PB148 Static Grizzly, as well as a range of heavy-duty conveyors, at its facility in Lake City, Pa.

Lake Erie Portable Screeners is heading into the new year positioned for growth.

The company, maker of Pitbull portable screeners, plans to launch several new products in 2019, including an all-new, compact Grizzly to be named the PB678 for its 6-ft. deep x 7-ft. high x 8-ft. wide dimensions.

Lake Erie also continues to invest in its manufacturing plant to increase efficiency and production capabilities. To that end, it recently acquired a Vision Wide SF Series 3-axis linear way machining center for component machining and mold cutting, as well as an Honor VL-160C vertical boring mill.

In a move to streamline sales for public sector jobs, Lake Erie applied for and was granted vendor status by HGACBuy, a nationwide procurement service that operates a purchasing cooperative for local governments and nonprofits, and by the federal government’s System for Award Management.

HGACBuy contracts are based on the requirements of Texas Local Government Code, Chapter 252, and are used throughout the United States.

Prequalified HGACBuy members benefit from a streamlined approval process that eliminates the need for governmental organizations to subject them to the often lengthy bid process. Lake Erie was

approved as a manufacturer of earthmoving, construction, and street -maintenance equipment.

Lake Erie Portable Screeners designs, engineers and manufacturers all of its products at its headquarters in Lake City, Pa. The company’s lineup includes the flagship Pitbull 2300, with diesel engine & built in conveying system, the Pitbull 2300B, a portable, heavy-duty box screening machine noted for its rugged design and high production yields; the Pitbull 2300P, a propane-fueled model offering the same high productivity and durability as the 2300; the Pitbull PB148 Static Grizzly; and a range of heavy-duty conveyors.

There will be more than 450 exhibitors at World of Asphalt.

EARTHQUAKE from page 6 completely shut down and we donâ&#x20AC;&#x2122;t normally do that.â&#x20AC;?

But the work is far from finished, said Sean Baski, ADOT design project manager. Baski put in 85 hours the week following the quake. The repaired roadways seem stable now, likely because the frozen ground is holding things together. â&#x20AC;&#x153;Come this spring when things start thawing out, thatâ&#x20AC;&#x2122;s a huge concern for us,â&#x20AC;? he said. â&#x20AC;&#x153;Our efforts are definitely not done.

We wonâ&#x20AC;&#x2122;t know until this summer.â&#x20AC;?

Baski praised the contracting community for their quick response and hard work, and called ADOT maintenance crews the â&#x20AC;&#x153;unsung heroesâ&#x20AC;? of the story. â&#x20AC;&#x153;I got a call at 2 in the morning from some of our construction crews that couldnâ&#x20AC;&#x2122;t keep their equipment on the road because of ice,â&#x20AC;? Baski said. â&#x20AC;&#x153;They needed maintenance operators to go out there and sand. We had our maintenance crews out there on site within a half-hour to 45 minutes putting down sand. Without that they wouldnâ&#x20AC;&#x2122;t have been able to finish paving. â&#x20AC;&#x153;Local law enforcement also played a huge role. They were helping to identify sites and make sure things were passable. When they found what they deemed to be unsafe conditions, they would call us to put out traffic control to make sure people could see where the conditions were less than ideal. And then after that, once we had a contractor available, we would send them out to fix it. It was a big team effort.â&#x20AC;?

rubble master Rubble Master’s HS3500M 4 by 9 ft. scalper screen screening topsoil.

Rubble Master scalper screens process a variety of waste products such as C&D waste, asphalt slabs and millings, topsoil, gravel, mulch and much more. Due to the heavy-duty design, this screen tackles the toughest remediation projects. Customers can choose from a variety of screen sizes to get up to three finished endproducts. Already being nicknamed the “Swiss-ArmyKnife” because of its versatility, it’s a must have for any contractor, according to the manufacturer.

The RM HS3500M features a 4 by 9 ft. screen-box with an excellent weight / performance ratio. This screen can be fed with an excavator or front-end loader.

A feed conveyor in the hopper conveys the material onto the screen-deck. Oversize material flows over the heavy-duty top deck and is discharged in front of the machine without passing any obstructions. Mid-size

material (clear product) falls through the first deck and is collected on the second deck and discharged to the right. Fines fall through both decks and are discharged to the left.

The HS-series scalping screens are easily, quickly and safely setup for a variety of applications. All conveyors fold hydraulically for transport. Side conveyors fold over the top to prevent any unwanted belt damages.

Like all Rubble Masters it can be loaded and unloaded quickly, safely and without the need of any special hand tools or support equipment.

Rubble Master offers four scalping screen models, six incline screen models and 60 and 80 ft. tracked stackers.

PAVING

through the decades Special to CEG Working to preserve the history of the construction equipment that shaped our world . . .

The Historical Construction Equipment Association (HCEA) is a non-profit organization dedicated to preserving for public education the history of the construction, dredging and surface mining equipment industries.

The Barber-Greene 879 paver was one of the first successful asphalt pavers to work independently of forms, and it established the basic design for all such machines into the present day. This is the second version, an 879-A. The Koehring rotary grader from the early 1920s is the indirect ancestor of todayâ&#x20AC;&#x2122;s milling machines. Capable of loading 60 to 100 cu. yds. per hour, it could handle macadam pavement or dirt, and an optional screen could separate out aggregates from the macadam. The discharge conveyor could be set to either side of the cutting wheel, and cutting depth was 2 in. to 2 ft. It was steered by operating one crawler to pivot on the other.

The Adnun paver with Galion three-wheel roller was a primitive asphalt paver that operated like an oversized spreader box.

From the late 1940s into the 1960s, three-drum tandem rollers provided extra full-width compaction force in asphalt work.
