The supplier refuted including PPA, but decreased to disclose what had been contributed to the binder. When pressed 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 consists of a percentage of phosphorus, which is what department chemists at first determined.


"No person understood this material was being contributed to asphalt, had actually seen any type of study on how this may impact efficiency of hot-mix asphalt sidewalks, or understood for the length of time and exactly how widely it was being utilized throughout the nation," claims Mueller.
