The supplier rejected including PPA, yet declined to disclose what had been added to the binder. When pushed by the division of transport, the vendor revealed that it was including what it called an asphalt extendernow understood to be re-refined engine oil bottoms (REOB).

"No person recognized this material was being included in asphalt, had seen any type of research study on exactly how this may impact efficiency of hot-mix asphalt pavements, or recognized for for how long and exactly how commonly it was being used throughout the nation," claims Mueller.
