RECOVERY AND REUSE OF ASPHALT ROOFING WASTE: INCORPORATION OF ROOFING WASTE IN ASPHALT PAVING. VOLUME 2: LABORATORY INVESTIGATION
Laboratory test results obtained in this preliminary study indicate the following: Acceptable paving mixtures can be produced which contain 20 vol % roofing waste. With a proper selection of binder type, binder quantities, and aggregate gradations, mixtures containing roofing waste quantities to and perhaps beyond, 30% can probably be prepared with acceptable properties. The type of binder selected for use in a mixture containing roofing waste should be based on the stiffness (penetration and viscosity) of the asphalt cement in the roofing waste. Improved asphalt cement extraction and recovery processes need to be developed for roofing waste in order to effectively determine the properties of the asphalt cement in the roofing waste. Gradations of conventional aggregates and roofing wastes should be considered when designing paving mixtures.
