Caterpillar

With the introduction of the 8-foot-class AP500E wheeled and AP555E tracked asphalt pavers, Caterpillar has brought larger-paver technology and features to the commercial paving market. The material-handling system utilizes four individual pumps that enable each conveyor and auger to deliver the exact amount of mix to the screed. The left and right conveyors and left and right augers are controlled independently, ensuring mix demand is met when shifting paving widths. When equipped with the AS2252C screed, the AP500E and AP555E operate at 33,715 and 35,290 pounds respectively. Write 001 on Reader Service Card.

Bomag

Bomag’s intelligent compaction system is now available on a second 78-inch asphalt roller. The Asphalt Manager system automatically optimizes the BW278AD4 AM tandem vibratory roller’s compaction performance during operation, continuously measuring the stiffness of the asphalt mat and adjusting compaction force where needed. The real-time display allows the operator to constantly monitor asphalt surface temperature, material stiffness, roller speed and amplitude. Proof rolling with the system allows base work to be inspected prior to paving. Write 002 on Reader Service Card.

Dynapac

Available in three- or four-wheeled configurations, the PL500T and PF500TD represent a new generation of compact cold planers from Dynapac. At 110 and 130 horsepower respectively, increased output from the Cummins QSB 4.5 diesel engines ensures improved performance and maximum cutting depths of 6.3 inches for the PL500T and 7.9 inches for the PL500TD. Special drums for demarcation work and fine spaced cutting drums are easy to change. Smaller drums with an adapted scraper blade and a side cutting wheel are available as options.

Wirtgen

The new Wirtgen W 200 and W 210 cold mills can both be equipped with milling drum assemblies of 59, 79 or 87 inches. Three selectable engine speeds enable a broad range of applications, from fine milling, to large-scale surface course rehabilitation, to complete pavement removal at full 13-inch cutting depth. The 59,934-pound W 200 is powered by a single engine generating 550 horsepower; the 62,138-pound W 210 boasts a unique fuel-saving drive concept utilizing two diesel engines, generating a total 671 horsepower.

Volvo

Available for the L150F, L180F and L220F wheel loaders in the 5- to 7-cubic-yard range, Volvo’s new OptiShift driveline system option provides claimed fuel savings up to 12 percent compared to the same machines not equipped with OptiShift. Competitive testing in short-cycle loading and level/uphill load-and-carry have shown up to 30-percent lower fuel consumption versus major competitors. A refinement of the Volvo APS driveline concept, OptiShift features the patented Reverse By Braking function and a new torque converter with lock-up and free wheel stator.

Roadtec

Following the lead of the flagship Shuttle Buggy 2500, Roadtec announces that all of its material transfer devices are now using direct-drive technology, changing over from axles and gears to hydraulic motors that control each wheel. The SB-1500 is a more compact version of the 2500; the MTV-1000 on display at World of Asphalt uses a patented offset gravity transfer chute to reblend material just before delivery to the truck. The upgrade makes the machines easier to shift, easier to work on and more durable, says Roadtec, an Astec company. Write 006 on Reader Service Card.
