ABSTRACT:
An apparatus for heating and mixing an asphalt-aggregate composition comprises a drum rotatable about an axis, having a mixing and heating chamber with a restricted port at one end into which a flame and hot gases of combustion are directed and through which exhaust gases simultaneously pass to atmosphere, and a heating means comprising a burner nozzle for directing flame and the hot gases of combustion into the chamber at the restricted port. The nozzle is adjusted relative to the port whereby the volatiles from the asphalt are ignited and burned within the mixing chamber prior to being vented to the atmosphere from the restricted port. Composition may also be introduced and/or removed from the chamber through the restricted port.
