ABSTRACT:
A windrow-type paving machine movable along a windrow of paving material includes a loading conveyor operable to transfer the upper portion of the paving material within the windrow into a hopper. The remainder of the paving material remains on the roadway and passes through a tunnel formed in the paving machine to a lateral auger and screed which cooperate to spread and level the paving material. The machine provides a hopper which receives the upper portion of the paving material for subsequent delivery by a conveyor to the lateral auger and screed when insufficient paving material passes through the tunnel to produce the required paving. Agitator means are provided in the tunnel to break up lumps of paving material and the like before they reach the auger.
