ABSTRACT:
An apparatus for and a method of recycling asphaltic waste shingles. The apparatus includes an elongated conversion tank into which an asphaltic oil, preferably preheated, and shingle tabs are admitted. The shingle tabs are dissociated into substantially liquified and solid shingle materials. The dissociated shingles are agitated with the asphaltic oil to form a slurry which can be drawn off and discharged to a work station. During the agitation, the substantially solid shingle materials are shredded to reduce their size. Preferably, the asphaltic oil is of a higher penetration grade than the asphaltic content of the shingles when in a substantially liquified form.
