Investigation of two warm mix asphalt additives... In this study, two commercial WMA additives, a proprietary siloxane-based compound and an oxidized polyethylene wax, were added to a soft Roofing Asphalt Flux (RAF), a soft Recycled Engine Oil Bottom (REOB) tainted binder, and a somewhat harder binder containing 20% oxidized asphalt derived from Recycled Asphalt Pavement (RAP)....

Alteration of π‑electron distributionto induce deagglomeration in oxidized polar aromatics and asphaltenesin an aged asphalt binder... To better link findingsto real-world materials and application, the study is done on theoxidized asphaltene and resin molecules; in addition, the disturbanceof electron distribution is done using a biorejuvenator derived fromanimal waste....
High-quality asphalt binders produced by deasphalting of natural bitumen... Bituminous materials produced by deasphalting were characterized by higher bitumen melting point, compared to oxidized asphalt at the same penetration level....
