Rejuvenating compositions for asphalt applications & methods of manufacturing the same

Abstract

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.
