Abstract:
Disclosed herein are an asphalt concrete mixture, an asphalt binder composition, and methods of preparing the related compositions. The asphalt binder compositions include heavy oil fly ash that contains more than about 90 wt. % carbon. The compositions are capable of being performance graded. The binder can be used to modify the asphalt and also as a filler in asphaltic concrete compositions.
