NewRoadProducts Special coverage from the World of Asphalt trade show in San Antonio and the MidAmerica Trucking Show in Louisville Dynapac Transverse-engined soil compactors Dynapac introduced a new range of soil compactors at World of Asphalt with a transversely-mounted engine ��� a design move which makes almost all of the engine easily accessible to mechanics when the hood is lifted. Dynapac says the sideways engine eliminates a problem common with the larger Tier 4i engines, which, traditionally mounted with the cooling package at the rear and the engine in front of that, can require mechanics to reach over wheels to get at the engine.The compactors range from 12 tons (CA 2500) to 15 tons (CA4000), and feature an 84-inch drum and an Active Bounce Control system that provides basic stiffness feedback and ���eliminates the chance of over compaction,��� says the company. Bomag Economizer now on BW138AD roller At its World of Asphalt booth in San Antonio, Bomag featured its update to the BW138AD tandem roller, which now has the Bomag���s Economizer technology as an option. The Economizer provides operators with a real-time reading of soil stiffness during the compaction process. The Economizer uses an acceleration sensor to measure stiffness across the compacted material, then displays the data using a series of ten yellow LED lights on the roller���s instrument panel. The lights stop increasing when maximum compaction has been achieved and suddenly drop to indicate a weak spot in the material. The Economizer also uses a red LED light on the display to warn the operator of potential over-compaction. The BW138AD-5 has a maximum centrifugal force of 10,800 pounds, a working width of 54.3 inches and 35.4-inch diameter drums. Volvo Bigger, better roller Volvo introduced its DD110B asphalt compactor at World of Asphalt today. The roller, which is replacing the DD90, features larger drums, more amplitude, higher frequency, increased centrifugal force and more water storage (made possible with two tanks) than its predecessor and is powered by a Tier 4i Volvo engine. Volvo also included a new operator system with new features like a six-way adjustable seat, tilt steering wheel, instrument cluster and a newlydesigned ROPS canopy.This compactor has three drum options: 2-amplitude high frequency, 8-amplitude high frequency and 8-amplitude high frequency and altitude.
