The disclosed invention is a method for using collagen extracted from animal bones, hides, and flesh waste as a protein-based glue (Bone Glue) to create asphalt with a modified asphalt binder. The method comprises of mixing Bone Glue with water, adding it to an asphalt binder, evaporating the water, adding the modified binder to aggregate and mixing at an elevated temperature. The modified asphalt binder consists of a predetermined amount of Bone Glue and asphalt binder.

Disclosed herein are rejuvenating compositions for asphalt applications. In one aspect, the rejuvenating composition comprises a polymerized oil having a polymeric distribution ranging from about 2 to about 80 wt % oligomer content and Hildebrand solubility ranging from about 6 to about 12. In another aspect, the rejuvenating composition comprises an oil having a Hildebrand solubility ranging from about 6 to about 12 and a flash point ranging from about 100 C. to about 400 C. In yet another aspect, the rejuvenating composition comprises a modified oil having a Hildebrand solubility ranging from about 6 to about 12 and a flash point ranging from about 100 C. to about 400 C.
