The supplier rejected adding PPA, however decreased to expose what had actually been contributed to the binder. When pressed by the division of transportation, the vendor exposed that it was adding what it called an asphalt extendernow known to be re-refined engine oil bottoms (REOB). REOB includes a small quantity of phosphorus, which is what division drug stores at first determined.

"Nobody understood this material was being included in asphalt, had seen any research study on just how this could impact efficiency of hot-mix asphalt pavements, or knew for the length of time and how extensively it was being utilized throughout the country," claims Mueller.
