The supplier rejected adding PPA, but declined to reveal what had actually been added to the binder. When pushed by the division of transportation, the supplier disclosed that it was including what it called an asphalt extendernow recognized to be re-refined engine oil bottoms (REOB).

"Nobody knew this product was being contributed to asphalt, had actually seen any study on exactly how this could impact performance of hot-mix asphalt pavements, or knew for how much time and exactly how widely it was being used throughout the country," states Mueller.
