Abstract
A paving machine discharges HMA or other paving materials directly on top of a distributing auger located between the paving material storage hopper and the screed. The distributing auger is then capable of remixing any partially segregated paving materials and of uniformly distributing the paving materials directly adjacent a previously-paved segment. Materials may be discharged on top of the distributing auger from a discharge opening of a gravity feed hopper located adjacent the distributing auger or from an inclined conveyor delivering materials from a more standard hopper mounted near the front end of the paving machine.
