Bobcat Bobcat's asphalt preservation tools system has an infrared asphalt heater and an asphalt processor compatible with 12 Bobcat all-wheel, skid-steer and track loader models: A300, A770, S300, S330, S750, S770, S850, T300, T320, T750, T770 and T870. The 3,760-pound AH30 heater is 59 inches long, 84.4 inches high and 111.4 inches wide. Wirtgen Wirtgen's AutoPilot Field Rover, which won an innovation award at bauma 2013, eliminates stringlines using a GPS to guide paving machines. The device uses a computer integrated into the machine, GPS receivers mounted on the paver and a control panel. To create the stringline, the receivers communicate with a GPS reference Caterpillar Caterpillar's four D Series skid steers, replacements for their B3, C and C2 Series predecessors, have a standard sealed and pressurized, one-piece modular construction cab. The series also has new lift arm design for improved sight lines, as well as increased engine performance. The D Series large-frame 246D and 262D models have operating capacities of 2,150 and 2,700 pounds, respectively. Trimble Introduced at bauma 2013, Trimble's Version 2.1 of the PCS900 Universal Total Station Paving Control System for milling machines – a 3D asphalt milling solution – is designed to help contractors mill a smoother surface. The portable 3D milling solution is CAN-based, which allows the system to communicate directly with factory-installed 2D systems from most milling machine manufacturers. Dynapac Dynapac's soil compaction machines have a transversely mounted engine – a design move that makes almost the entire engine accessible to mechanics when the hood is lifted. The soil compactors range from 12 tons (CA 2500) to 15 tons (CA4000), feature an 84-inch drum and an active bounce control system of feedback that provides basic stiffness feedback. 14 December 2013 Better Roads
