  • Asphalt mastic utilizing petroleum refinery waste solids

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.
