The supplier refuted adding PPA, but decreased to expose what had actually been included in the binder. When pressed by the division of transportation, the vendor revealed that it was including what it called an asphalt extendernow known to be re-refined engine oil bottoms (REOB). REOB has a percentage of phosphorus, which is what department chemists originally determined.


"No person understood this product was being included to asphalt, had actually seen any kind of research study on how this may affect efficiency of hot-mix asphalt sidewalks, or understood for how much time and how widely it was being used throughout the nation," claims Mueller.
