Abstract: Recyclable asphalt material is processed within a drum for delivery in a heated mass containing aggregate-sized pieces for reuse. The drum is mounted for rotation about a longitudinal axis and a mounting arrangement compensates for thermal expansion and contraction of the drum while enabling the desired rotation. The mounting arrangement includes at least one mounting ring placed coaxial with the longitudinal axis and spaced from the drum by a radial spacing. Support rollers support the mounting ring for rotation about the longitudinal axis, and links couple the drum with the mounting ring. Each link has one end coupled pivotally to the drum, and another end coupled pivotally to the mounting ring. The ends of the link are offset circumferentially relative to one another such that the link is movable to vary the radial spacing in response to thermal expansion and contraction of the drum relative to the mounting ring.

Abstract: Apparatus and method are disclosed for processing recyclable asphalt material. A drum has a polygonal cross-sectional configuration providing a plurality of substantially flat wall sides. Tubular breaker members within the drum are juxtaposed with corresponding flat wall sides. The relative location of the breaker members and the flat wall sides effects a cascading of recyclable asphalt material over the breaker members and between the breaker members and the flat wall sides as the drum is rotated so that recyclable asphalt material is tumbled within the drum, thereby simultaneously reducing the size of relatively large pieces to aggregate-sized pieces and heating the mass containing the desired aggregate-sized pieces for delivery of the heated mass from the drum.

Abstract: Apparatus and method are disclosed in which recyclable asphalt material received from the field in relatively large pieces is processed within a drum for delivery in a heated mass containing desired smaller aggregate-sized pieces for reuse. The drum is provided with a drum wall having an inner surface with a polygonal cross-sectional configuration establishing an inner chamber bounded by a plurality of substantially flat wall sides. A cage-like array of tubular breaker members is placed within the inner chamber so that tubular breaker members are juxtaposed with corresponding flat wall sides. Recyclable asphalt material is fed into the array of breaker members, and heated gases are passed serially along a path of travel through a heat conduit and then through the breaker members.
