Paver Roundup from World of Asphalt
Not every paver-related original equipment manufacturer (OEM) brought a new launch to World of Asphalt 2022 in Nashville, but some of the iron on the tradeshow floor was seeing its debut for a North American market or for a tradeshow audience. For example, the 8520B asphalt paver from ST Engineering LEEBOY Inc., Lincolnton, North Carolina, was updated with assistance from the team at American Pavement Specialists LLC, Danbury, Connecticut, for the industry in 2021 and was on display for the first time at WOA, according to a LeeBoy salesperson onsite.
Another paver OEM who had a significant offering on hand was WEILER Inc., Knoxville, Iowa. WOA attendees would have seen a number of commercial class pavers in the vendor’s booth, as well as a variety of products for the paving contractor. The base designs for Weiler self-propelled road wideners and asphalt windrow elevators were created by Barber-Greene®, which many readers may remember was purchased by Caterpillar in the early 1990s. Weiler purchased designs from Caterpillar in 2005 and established the Weiler brand name. Since then, Weiler has manufactured products for the asphalt paving market including pavers, remixing transfer vehicles, road wideners, windrow elevators, static split-drum compactors and front-mount screeds.

The team from BOMAG not only showcased its CR1030 T paver, but also hosted a fundraiser for Construction Angels at the booth. The paver offers SideView, SMARTRAC, Frame Raise and Telematic technologies from Bomag in this 10- to 30-foot-wide paver. The fundraiser brought in $1,300 for the Construction Angels mission to provide immediate financial assistance and grief counseling to the families of construction workers who have lost their lives while working on the job site.

At the booth for DYNAPAC North America, Fort Mill, South Carolina, WOA attendees could check out the newest range of highway class pavers and screeds built specifically for the North American market: the D30T (10-foot track), the D30W (10 foot-wheel), the D25T (8-foot track), the D25W (8-foot wheel), Mat Master 16R (8- to 16-foot screed), and Mat Master 20R (10- to 20-foot screed). The D30T and D25T models offer iTrack ultra duty rubber track design and the D30W and D25W models offer dynamic suspension control (DSC) for optimum tractive effort and results needed for highway paving. The Mat Master screeds are equipped with DiveStop and Active Screed Assist.
The new pavers are built with dual independent tractor consoles and include the Dynapac smart dashboard and HMI design on the tractor and screed. Operators have access to Dynapac PaveManager, and assistance such as FeedAssist, CleanAssist, ImpactAssist, DiveStop, LightAssist are built in. The user-friendly swing out dashboards are equipped with toggle and rocker switches within easy reach. The contractor can customize the feed system on the new Dynapac highway class pavers to fit the comfort level of the crew—choose proportional dual sensor mode, proportional quad sensor mode or flow gate.
If the crew will be performing night paving, Dynapac points out its Flicker-free Generator system design, which allows the crew to directly connect the night-lights to the paver easily. The need of renting external generators and plugs are completely removed.
For the contractor looking at The Road Forward, Dynapac highway class pavers are equipped with ECO-Mode engine technology for lower fuel consumption and the overall design allows to operate the paver at lowest possible engine RPM, according to the manufacturer. Screed heating is also possible with ECO Zonal heating, designed to consume less power and fuel. The Mat Master screeds are also designed to handle a variety of mixes such as rubberized asphalt and warm-mix asphalt and others. The manufacturer states “We are with you to reduce carbon footprint with innovative mix design.” For more information, contact firstname.lastname@example.org.
The WIRTGEN booth included a cross section of Vögele pavers, including the SUPER 1800-3i SprayJet with fixed-width screed VR 600. The spray paver offers a unique modular machine concept allowing it to be used as a spray screed or as a standard screed to pave thin layers as well as conventional binder and surface courses. It has a maximum spray width of 19 feet, 6 inches. With the rear-mounted VR 600 screed, it’s designed to fulfill all requirements for asphalt paving.
The paver presented at the WOA was equipped with an additional emulsion tank, which can store 1,320 gallons emulsion in addition to the standard emulsion tank that stores 555 gallons. For more information, contact email@example.com or visit www.wirtgen-group.com.
At the CATERPILLAR booth, the company displayed its new compact line of asphalt pavers and screeds, launched in November 2021. These standard 8-foot size paver and screed combinations include the AP400, AP455, AP500, and AP555 asphalt pavers as well as the SE47 V and SE47 FM asphalt screeds. They come equipped with features for both urban and rural applications to fit the needs of both large and small contractors.
The compact size and small footprint combine with maneuverability for more opportunity to pave in confined areas such as narrow streets, small parking lots, and other urban-type applications. The standard paving range using the SE47 V screed is 8 feet to 15 feet, 6 inches (2.4 to 4.7 meters) with a maximum width of 20 feet (6.1 m), while the standard paving range of the SE47 FM screed is 8 feet to 15 feet, 6 inches (2.4 to 4.7 m) with a maximum width of 20 feet, 6 inches (6.2 m).
