Residue from the re-refining of waste engine oils, referred to as re-refined engine oil bottoms (REOB) or vacuum tower asphalt extender, has been used as a fluxing agent in asphalt binder blending for more than 40 years. This practice, called "fluxing," involves blending softer oils, or "fluxes" with a harder asphalt binder to produce intermediate asphalt binder grades for paving.
