Abstract: An elongated drum for mixing asphalt materials has a rear inlet end, a front outlet end and a side wall concentric to a substantially horizontal axis about which the drum rotates. For feeding salvaged asphalt material into the drum, the side wall has circumferentially spaced ports in a zone intermediate said ends. As ports move upwardly in their orbits, material falls toward them from the bottom outlet of a hopper above the drum and is guided into them by chutes, one for each port, that are fixed to the side wall and project out from it. Also, fixed to the side wall is an inwardly projecting spout for each port whereby material entering the port is deflected forwardly to fall to the bottom of the drum in front of the ported zone. Material moving forward from the rear of the drum is deflected around the ports by the spout walls. An annular trough-like shroud encircles the drum at said zone, embracing the chutes as they move orbitally and preventing incursion of external ambient air into the ports.
