The vendor denied adding PPA, yet decreased to expose what had actually been added to the binder. When pressed by the department of transport, the vendor disclosed that it was including what it called an asphalt extendernow known to be re-refined engine oil bottoms (REOB). REOB consists of a small amount of phosphorus, which is what department drug stores at first identified.


"No one knew this product was being included to asphalt, had actually seen any type of research on just how this may influence efficiency of hot-mix asphalt sidewalks, or understood for the length of time and exactly how commonly it was being used throughout the nation," claims Mueller.
