The supplier refuted including PPA, but declined to expose what had 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 recognized to be re-refined engine oil bottoms (REOB). REOB includes a little quantity of phosphorus, which is what division chemists initially determined.


"Nobody knew this product was being contributed to asphalt, had actually seen any type of research study on how this could influence efficiency of hot-mix asphalt pavements, or knew for the length of time and just how extensively it was being made use of throughout the country," states Mueller. After discussions at the technical conference, he states, "It rapidly went from being simply an issue in Illinois to becoming a nationwide and international problem."

The equipment was not established for the paving market (https://moz.com/community/q/user/a1asphaltseal).
