The vendor denied including PPA, yet decreased to reveal what had actually been included in the binder. When pushed by the department of transportation, the vendor disclosed that it was adding what it called an asphalt extendernow understood to be re-refined engine oil bases (REOB). REOB has a small quantity of phosphorus, which is what division drug stores originally determined.


"No one understood this material was being included to asphalt, had actually seen any kind of research study on just how this might influence performance of hot-mix asphalt sidewalks, or knew for how much time and how commonly it was being used throughout the country," says Mueller. After discussions at the technical conference, he claims, "It rapidly went from being just a problem in Illinois to coming to be a nationwide and global worry."
