The change in physicochemical properties due to fluxing propane precipitated asphalt (PPA) as well as blown asphalt grade 115/15 of marine belayim Oregon with long residue (LR), short residue (SR), and aromatic extract (AE) has been investigated. The devulcanization of crumb rubber with AE and the change in physicochemical properties due to fluxing PPA with low concentration devulcanized rubber (DV) and high concentration devulcanized rubber (DV”) led to compatible asphalt samples. The vulcanization of flux of PPA with DV and DV” and studying the emulsification of rubberized and unrubberized asphalt indicated their suitability for application.
