ABSTRACT:
An improved asphaltic concrete recycling apparatus comprises an elongated drum having an open inlet port at a first drum end and a product recovery port adjacent a second and opposite drum end, a burner adjacent the first drum end for introducing hot gases of combustion into the inlet port, and an elongated sleeve extended along the interior of the drum intermediate the first and second ends for directing the hot gases of combustion toward the second drum end. In the preferred embodiment, the first end of the sleeve is located in a portion of the drum where a veil of composition is avoided during drum rotation, and the second sleeve end is located in a drum portion where a curtain or veil of composition is formed.
