ABSTRACT:
An apparatus for recycling asphaltic concrete comprises an elongated rotatable drum in which composition is introduced at a first end and recovered at the opposite second end, and having a burner extending into the drum so that the burner nozzle is located within the drum intermediate the first and second ends and directs the hot gases toward the first end, and wherein the portion of the drum between the burner and the first end is provided with lifters of a type which prevent the formation of a veil of composition particles from falling through the hot gases of combustion as the drum is rotated, and a second portion between the burner nozzle and the second drum end and which is provided with lifters which cause a veil of composition particles to pass through hot gases of combustion as the drum rotates.
