ABSTRACT:
Methods are disclosed for controlling the steering of a carrier vehicle having a horizontal compacting roller and a side edge confinement roller or shoe for compacting an asphalt concrete lane. In one embodiment, a sensor is on the carrier vehicle for sensing the position of a defined edge of the lane, and a control is provided for steering the carrier vehicle so that the horizontal roller and the edge confinement force roller or shoe follow the defined edge of the lane to provide uniform density. A method is also provided for controlling the compacting force of a horizontal compacting roller carried by a carrier vehicle.
