The supplier refuted including PPA, however declined to expose what had actually been included in the binder. When pressed by the division of transportation, the supplier exposed that it was including what it called an asphalt extendernow understood to be re-refined engine oil bottoms (REOB). REOB includes a little quantity of phosphorus, which is what department chemists at first identified.


"No one knew this product was being included in asphalt, had actually seen any kind of study on how this could influence efficiency of hot-mix asphalt sidewalks, or understood for for how long and just how extensively it was being utilized throughout the country," claims Mueller.
