The vendor denied adding PPA, yet decreased to disclose what had been added to the binder. When pushed by the department of transport, the supplier revealed that it was including what it called an asphalt extendernow understood to be re-refined engine oil bottoms (REOB). REOB contains a percentage of phosphorus, which is what department drug stores at first identified.

"No person understood this material was being included to pop over here asphalt, had seen any study on exactly how this might influence efficiency of hot-mix asphalt sidewalks, or understood for how much time and how extensively it was being used throughout the nation," says Mueller. After conversations at the technical meeting, he states, "It rapidly went from being simply a problem in Illinois to becoming a national and international issue."
