摘要： 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.

摘要： An acid modified asphalt binder is combined with an emulsifier solution to produce an emulsified asphalt binder. The acid modified asphalt binder may be formed by combining an asphalt binder, a phosphorous-based acid, and, optionally, a polymer modifier. The emulsifier solution may be produced by forming an aqueous solution of an amine and a phosphorous-based acid, which forms an aqueous solution comprising an amine phosphate. The emulsified asphalt binder may be combined with an aggregate to form a paving material. In other examples, the emulsified asphalt binder may be used alone, for example in a chip seal application, or in a diluted form, for example in a fog seal application.

摘要： This disclosure describes further age retarding additives for asphalt binders. These additives comprise three structural elements i) a fused hydrocarbon ring structure, ii) a polar element attached to the ring structure, and iii) an aliphatic element attached to the ring structure opposite the polar element.
