The vendor denied adding PPA, yet decreased to expose what had been contributed to the binder. When pushed by the department of transport, the vendor exposed that it was adding what it called an asphalt extendernow recognized to be re-refined engine oil bottoms (REOB). REOB contains a little quantity of phosphorus, which is what division drug stores originally determined.

"Nobody recognized this product was being contributed to asphalt, had seen any type of research study on how this might affect performance of hot-mix asphalt sidewalks, or recognized for the length of time and exactly how commonly it was being made use of throughout the country," claims Mueller.
