The supplier refuted including PPA, however declined to reveal what had been included in the binder. When pushed by the department of transportation, the vendor revealed that it was including what it called an asphalt extendernow understood to be re-refined engine click resources oil bottoms (REOB). REOB contains a small quantity of phosphorus, which is what division chemists at first determined.

"No one knew this product was being contributed to asphalt, had seen any study on exactly how this may affect efficiency of hot-mix asphalt pavements, or knew for exactly how long and exactly how extensively it was being used throughout the nation," states Mueller. After discussions at the technological meeting, he claims, "It swiftly went from being just a concern in Illinois to ending up being a national and global issue."

The DSR allows product programmers to create toothpaste with the right uniformity so that it can be squeezed from a tube but not fall off the tooth brush. The DSR tests binder placed in between 2 parallel plates about the dimension of a quarter. Among the plates relocations and the machine measures the viscoelastic properties of the asphalt.
