Abstract
A self propelled paving machine includes a pair of independently operated conveyors and a pair of independently operated augers spaced on opposite sides of the machine centerline. The augers can be separately raised and lowered to different elevations. The drive boxes for the conveyors and augers are positioned at the sides of the machine, to provide space between the conveyors and augers that is unobstructed, permitting the free fall of paving material from the conveyors along the centerline of the machine.
