Abstract
An asphalt paving machine has spreading mechanism for distributing paving material to the roadway, a hopper, a conveyor forming the bottom of the hopper for moving paving material along a path extending through the hopper and to the spreading mechanism, and a device for mixing the paving material as it moves along the path. The mixing device includes at least one stationary weir member mounted within the hopper and spaced above the conveyor. The weir member is positioned in the path of the paving material and presents an upright surface having a bottom edge. The bottom edge of the weir member and the conveyor define a generally vertical passageway through which the paving material passes as it is moved by the conveyor.
