In the material-handling system of Ingersoll Rand's new highway-class pavers — the track-mounted 5110 and wheel-mounted 5160 and 5170 — the conveyor drives are independent of the auger drives. Each conveyor and auger measures material flow with a sonic sensor and adjusts asphalt flow for precise delivery. Basic screed width is 8 feet, with a maximum paving width of 28 feet. A 185-hp Cummins diesel drives through a hydrostatic transmission. It also features a 30kW tractor-mounted generator. Estimated list price: $299,000.
