ABSTRACT:
An asphalt heating and drying device for recycling or repairing asphalt. Nuggets of waste asphalt are inserted into a heat chamber that has a plurality of heat tubes that carry hot air into the chamber and adjacent to the waste asphalt nuggets. The heat chamber has a “live floor” with controllable spinning rotors which have forward reaching teeth. The spinning rotors pull the asphalt from the heat chamber into a lower chamber having two horizontal spiral augers. The augers mix the asphalt nuggets and the lower chamber heats the asphalt nuggets to their ultimate delivery temperature. The hot dry asphalt is then expelled from the device.
