Renewable Fuel Co-Products - Potential Uses in Asphalt

An area of rapid growth, particularly in the United States and Europe, is the production of renewable liquid transportation fuels. The potential for using co-products from this rapidly growing manufacturing base as blending components in asphalt is examined in this paper. Preparations of several blends of biofuel co-products in a paving grade asphalt binder were made, and measurements of performance grading properties were taken. In accordance with American Association of State Highway and Transportation Officials (AASHTO) T283 to evaluate resistance to moisture damage, asphalt concrete mixtures using the various blends and a somewhat moisture sensitive aggregate were tested. Some of these materials may be useful as binder extenders, having minimal impact on the performance grade while imparting added benefits, as indicated by initial laboratory findings.
