The supplier refuted adding PPA, but declined to disclose what had been included in the binder. When pushed by the department of transport, the vendor disclosed that it was adding what it called an asphalt extendernow known to be re-refined engine oil bases (REOB). REOB includes a small amount of phosphorus, which is what division chemists initially determined.

"No one recognized this material was being contributed to asphalt, had actually seen any research on exactly how this might influence performance of hot-mix asphalt sidewalks, or understood for how much time and how extensively it was being utilized throughout the nation," says Mueller.
