Abstract:
An asphalt binder includes asphalt and an asphalt binder modifier, which includes bio-oil. The asphalt binder can include a carboxyl additive. The asphalt can optionally include polymer-modified asphalt. An asphalt material includes mineral aggregate, an asphalt material binder including asphalt, and an asphalt binder modifier including bio-oil. A method for making the asphalt binder is disclosed. The asphalt material includes asphalt pavement and roofing shingles. The asphalt binder can be emulsified with water and a surfactant for use as a weatherproofing sealant or as an adhesive.
