The vendor refuted including PPA, but declined to reveal what had actually been added to the binder. When pushed by the department of transportation, the supplier disclosed that it was adding what it called an asphalt extendernow recognized to be re-refined engine oil bottoms (REOB). REOB includes a percentage of phosphorus, which is what department drug stores originally recognized.


"Nobody knew this material was being contributed to asphalt, had actually seen any study on how this could impact efficiency of hot-mix asphalt pavements, or understood for exactly how lengthy and just how widely it was being utilized throughout the nation," says Mueller. After discussions at the technological conference, he states, "It quickly went from being simply a concern in Illinois to ending up being a national and global issue."
