The vendor denied including PPA, yet declined to reveal what had been added to the binder. When pressed by the division of transportation, the vendor disclosed that it was adding what it called an asphalt extendernow understood to be re-refined engine oil bases (REOB). REOB includes a percentage of phosphorus, which is what department chemists originally identified.


"No person knew this product was being contributed to asphalt, had actually seen any type of research on how this could affect performance of hot-mix asphalt sidewalks, or recognized for exactly how long and exactly how widely it was being used throughout the country," states Mueller. After discussions at the technical meeting, he says, "It promptly went from being simply a problem in Illinois to coming to be a nationwide and international problem."
