The supplier denied adding PPA, however decreased to expose what had actually been added to the binder. When pressed by the department of transport, the supplier disclosed that it was including what it called an asphalt extendernow understood to be re-refined engine oil bottoms (REOB). REOB has a tiny quantity of phosphorus, which is what division chemists initially recognized.


"No one understood this product was being included in asphalt, had seen any study on just how this may affect efficiency of hot-mix asphalt pavements, or knew for the length of time and how widely it was being made use of throughout the nation," states Mueller. After discussions at the technological meeting, he says, "It swiftly went from being just an issue in Illinois to coming to be a nationwide and global problem."

The DSR examinations binder put between two identical plates concerning the dimension of a quarter. Among home plates steps and the machine determines the viscoelastic residential or commercial properties of the asphalt.
