Hunt, J; Shepherd, P

A novel concept for recovering the energy in the asphalt contained in the roofing waste involved dissolving the asphalt in roofing waste in No. 2 fuel oil, separating the solids from the liquid, and concentrating the liquid to No. 6 fuel oil. Experiments showed that this concept would be applicable to both factory and field asphalt roofing waste. Filtration was unsuitable for making the liquid/solid separation. Limited experiments using centrifuging as the liquid/solid separation process indicated that this is feasibile. The centrifuging process would be a means for recovery of much of the 7.3 x 10/sup 13/ Btu represented in the nation's annual roofing waste and would also have a major impact on reducing the six million cubic yards of roofing waste now hauled to landfills each year.
