Crude sterol as an additive in asphalt binder
Abstract The current application is directed to a method for slowing the aging rate of aged asphalt binder. The method comprises: adding a crude sterol to an asphalt binder, wherein the crude oil comprises sterols obtained from plant sources, wherein the asphalt binder comprises a virgin asphalt binder, reclaimed asphalt binder material obtained from asphalt comprising asphalt pavement (RAP), asphalt shingles (RAS) or combinations of both and from 0.5 to 15 wt. % of the crude sterol based on the virgin asphalt binder, wherein the crude sterol slows the aging rate of the asphalt binder composition, and wherein the asphalt binder comprises up to 55 wt. % reclaimed asphalt binder material obtained from asphalt pavement (RAP), up to 27 wt. % reclaimed asphalt binder material obtained from asphalt comprising asphalt shingles (RAS), or up to 60 wt. % reclaimed asphalt binder material obtained from a combination of asphalt pavement (RAP) and asphalt shingles (RAS).
