ABSTRACT:
An improved recycling apparatus for particulate asphaltic concrete comprises a rotatable drum in which the particulate composition is gradually heated between an input end and an output end having a retractable chute extending into a port at the output end for recovering composition of a selected temperature. The chute contains a temperature sensing device, and the apparatus preferably includes a drive means for inserting or retracting the chute, and thermostat means for selecting a product temperature whereby the drive means causes the chute to be extended into the drum to recover the composition of a selected temperature. In another embodiment, the drum includes first, second, and third lifters each extending along different respective lengths of the drum interior to achieve different exposure of the particulate composition to the heating gases in the drum in the respective different drum sections to achieve improved heating and mixing efficiency.
