The supplier refuted including PPA, but declined to expose what had actually been included to the binder. When pushed by the division of transportation, the supplier revealed that it was adding what it called an asphalt extendernow recognized to be re-refined engine oil bottoms (REOB). REOB includes a percentage of phosphorus, which is what division drug stores originally identified.


"Nobody understood this product was being contributed to visit this page asphalt, had seen any kind of research study on just how this may influence efficiency of hot-mix asphalt pavements, or knew for for how long and just how extensively it was being utilized throughout the nation," says Mueller.
