The vendor denied adding PPA, yet declined to disclose what had actually been added to the binder. When pressed by the division of transport, the supplier exposed that it was including what it called an asphalt extendernow recognized to be re-refined engine oil bases (REOB). REOB includes a percentage of phosphorus, which is what division drug stores at first identified.


"No one knew this material was being contributed to asphalt, had seen any kind of research study on exactly how this may affect performance of hot-mix asphalt pavements, or recognized for how long and exactly how widely it was being used throughout the country," states Mueller. After discussions at the technical meeting, he says, "It rapidly went from being simply a concern in Illinois to ending up being a national and international worry."
