The supplier refuted adding PPA, but declined to disclose what had actually been included in the binder. When pressed by the department of transport, the supplier exposed that it was including what it called an asphalt extendernow understood to be re-refined engine oil bottoms (REOB). REOB includes a percentage of phosphorus, which is what department chemists originally determined.


"Nobody knew this material was being included to asphalt, had seen any research on exactly how this might affect 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," claims Mueller. After conversations at the technical conference, he claims, "It rapidly went from being just an issue in Illinois to ending up being a national and global problem."
