The supplier refuted including PPA, however decreased to expose what had been included in the binder. When pressed by the division of transportation, the vendor revealed that it was including what it called an asphalt extendernow recognized to be re-refined engine oil bases (REOB). REOB has a tiny quantity of phosphorus, which is what division chemists initially recognized.


"No person understood this material was being included to asphalt, had actually seen any type of research on how this could influence efficiency of hot-mix asphalt pavements, or knew for how much time and just how commonly it was being utilized throughout the nation," states Mueller. After discussions at the technical conference, he states, "It rapidly went from being simply a concern in Illinois to coming to be a national and global worry."
