The vendor denied including PPA, however declined to reveal what had been added to the binder. When pushed by the department of transport, the vendor revealed that it was adding what it called an asphalt extendernow recognized to be re-refined engine oil bases (REOB). REOB includes a tiny quantity of phosphorus, which is what division chemists originally identified.


"No person knew this product was being added to asphalt, had seen any type of research on just how this might affect performance of hot-mix asphalt sidewalks, or understood for exactly how long and just how commonly it was being used throughout the country," says Mueller. After discussions at the technological meeting, he says, "It quickly went from being just an issue in Illinois to ending up being a national and international worry."

The DSR enables item designers to produce tooth paste with the ideal consistency so that it can be pressed from a tube however not fall off the tooth brush. The DSR tests binder positioned in between two identical plates regarding the size of a quarter. Among the plates moves and the equipment determines the viscoelastic buildings of the asphalt.
