The supplier refuted adding PPA, yet declined to expose what had actually been included in the binder. When pressed by the division of transport, the vendor exposed that it was adding what it called an asphalt extendernow known to be re-refined engine oil bottoms (REOB). REOB has a tiny quantity of phosphorus, which is what division chemists initially determined.


"No one understood this material was being included to asphalt, had actually seen any type of research on how this may influence performance of hot-mix asphalt sidewalks, or knew for the length of time and how widely it was being made use of throughout the nation," says Mueller. After discussions at the technical conference, he states, "It swiftly went from being simply a concern in Illinois to ending up being a national and worldwide problem."

A machine called a dynamic shear rheometer (DSR) was presented to the market throughout the Strategic Freeway Research Program's research study project, which ranged from 1987 to 1992.
