Abstract:
Disclosed herein are an asphalt concrete mixture, an asphalt binder composition, and methods of preparing the related compositions. The asphalt binder compositions include a polyphosphoric acid, a macromolecular polymer having a saturated backbone with macromolecular modifications, sulfur, and non-surfactant additives based on wax chemistry. The compositions are capable of being performance graded and being used in warm mix asphalt applications.
