Abstract
Continuous asphalt plant including a temperature control system for controlling the temperature of the asphalt-aggregate mix by varying the flow of hot gases through a mixing enclosure. The temperature of the source of heat, such as a flame burner, is controlled to maintain the temperature of the hot gases as they enter the mixing enclosure, and the hot gases are recirculated to assist in controlling the temperature of the hot gases entering the mixing enclosure and to provide more efficient operation of the plant.
