The supplier rejected including PPA, yet declined to disclose what had actually been included in the binder. When pressed by the department of transport, the supplier exposed that it was adding what it called an asphalt extendernow known to be re-refined engine oil bases (REOB). REOB contains a little amount of phosphorus, which is what division drug stores at first identified.


"No person recognized this material was being included to asphalt, had actually seen any research on just how this may impact performance of hot-mix asphalt pavements, or knew for for how long and exactly how commonly it was being used throughout the country," says Mueller. After conversations at the technical meeting, he claims, "It swiftly went from being just an issue in Illinois to coming to be a national and global problem."
