Abstract:
Disclosed are asphalt binder compositions that contain at least one sterol or stanol additive, or blends of sterols and stanol additives, wherein the sterol or stanol additive is derived from an animal waste or manure source such as swine manure. These sterol and stanol-based additives improve various rheological properties of the asphalt binder compositions showing reduced and/or mitigated aging characteristics.
