Abstract:
A paving apparatus for placing a mat of hot mix asphalt material on a subgrade as the paving apparatus is moved along a path, comprising:a) a hopper for receiving the hot mix asphalt material;b) a spreader arranged to distribute the hot mix asphalt material generally transversely from a longitudinal axis of the apparatus to form a mat; andc) a conveyor including at least one pair of spaced apart axially rotatable feed augers disposed generally parallel to the path and being arranged to draw the hot mix asphalt material from along the length of the hopper and to convey the hot mix asphalt material from the hopper to the spreader, each of the feed augers including a shaft and having helical flighting, each of the feed augers further including at least one remixing blade mounted to the shaft, the remixing blade being spaced between adjacent flighting and being adapted to displace the hot mix asphalt material intermittently and generally transversely upon rotation of the feed augers, the conveyor being arranged to substantially continuously remix the hot mix asphalt material along the length of the conveyor as the hot mix asphalt material is being conveyed to the spreader.
