The vendor refuted adding PPA, however declined to reveal what had been included to the binder. When pressed by the division of transport, the vendor exposed that it was including what it called an asphalt extendernow recognized to be re-refined engine oil bottoms (REOB). REOB consists of a small quantity of phosphorus, which is what division chemists initially identified.


"No person understood this product was being included to asphalt, had actually seen any type of study on how this may impact performance of hot-mix asphalt sidewalks, or understood for for how long and exactly how commonly it was being used throughout the nation," states Mueller.
