The vendor denied including PPA, yet decreased to reveal what had actually been included to the binder. When pressed by the division of transport, the supplier exposed that it was adding what it called an asphalt extendernow understood to be re-refined engine oil bottoms (REOB).

"Nobody knew this product was being included to asphalt, had actually seen any kind of research on how this could impact performance of hot-mix asphalt pavements, or recognized for the length of time and how commonly it was being made use of throughout the country," claims Mueller.
