ASPHALT MASTIC UTILIZING PETROLEUM REFINERY WASTE SOLIDS

摘要

An asphalt mastic is prepared by combining comminuted waste solids from a petroleum refinery with liquid asphalt that is either a hot asphalt or an asphalt emulsion. The resulting composition is similar in performance to Trinidad Lake Asphalt and is useful either on its own or as a binder for asphalt-aggregate compositions, in both cases optionally in combination with polymeric additives that are common in the asphalt industry.
