The supplier denied adding PPA, however decreased to disclose what had been contributed to the binder. When pushed by the division of transportation, the vendor revealed that it was including what it called an asphalt extendernow understood to be re-refined engine oil bottoms (REOB). REOB consists of a percentage of phosphorus, which is what department chemists originally recognized.


"No person understood this material was being contributed to asphalt, had actually seen any type of research on how this might influence efficiency of hot-mix asphalt sidewalks, or understood for how much time and just how commonly it was being used throughout the nation," says Mueller. After discussions at the technological conference, he claims, "It rapidly went from being simply a problem in Illinois to becoming a national and global issue."

A maker called a vibrant shear rheometer (DSR) was introduced to the industry throughout the Strategic Highway Research Program's research job, which ran from 1987 to 1992.

The DSR enables item designers to develop toothpaste with the right uniformity so that it can be squeezed from a tube yet not fall off the toothbrush. The DSR tests binder placed in between two identical plates about the dimension of a quarter. One of home plates relocations and the maker measures the viscoelastic properties of the asphalt.
