The vendor refuted adding PPA, but decreased to disclose what had been contributed to the binder. When pressed by the division of transport, the supplier revealed that it was adding what it called an asphalt extendernow known to be re-refined engine oil bases (REOB). REOB has a percentage of phosphorus, which is what department drug stores originally recognized.


"No one understood this material was being contributed to asphalt, had seen any kind of study on how this could impact efficiency of hot-mix asphalt sidewalks, or knew for the length of time and just how widely it was being used throughout the country," states Mueller. After conversations at the technological meeting, he claims, "It promptly went from being just a problem in Illinois to coming to be a national and international issue."

A machine called a vibrant shear rheometer (DSR) was presented to the market throughout the Strategic Freeway Study Program's research task, which ran from 1987 to 1992.

The DSR enables product designers to produce tooth paste with the best consistency so that it can be squeezed from a tube yet not drop off the toothbrush. The DSR tests binder positioned in between 2 identical plates about the dimension of a quarter. Among home plates relocations and the machine determines the viscoelastic residential properties of the asphalt.
