The supplier refuted including PPA, but decreased to reveal what had been contributed to the binder. When pushed by the department of transport, the supplier revealed that it was including what it called an asphalt extendernow understood to be re-refined engine oil bases (REOB). REOB consists of a percentage of phosphorus, which is what division chemists originally determined.


"No one knew this product was being contributed to asphalt, had actually seen any type of research on how this may impact efficiency of hot-mix asphalt pavements, or knew for for how long and exactly how commonly it was being made use of throughout the nation," claims Mueller.
