The supplier refuted including PPA, yet decreased to disclose what had been contributed to the binder. When pressed by the department of transportation, the supplier revealed that it was adding what it called an asphalt extendernow known to be re-refined engine oil bases (REOB). REOB has a percentage of phosphorus, which is what department drug stores initially recognized.


"No person recognized this product was being contributed to asphalt, had actually seen any research study on exactly how this may influence performance of hot-mix asphalt sidewalks, or recognized for how much time and exactly how widely it was being used throughout the nation," states Mueller. After conversations at the technological meeting, he states, "It swiftly went from being just a problem in Illinois to ending up being a nationwide and global problem."
