The vendor denied adding PPA, yet decreased to disclose what had been included in the binder. When pushed by the department of transport, the vendor disclosed that it was including what it called an asphalt extendernow recognized to be re-refined engine oil bases (REOB). REOB contains a percentage of phosphorus, which is what department chemists originally recognized.


"Nobody knew this product was being added to asphalt, had actually seen any type of research on just how this may impact performance of hot-mix asphalt sidewalks, or knew for how much time and exactly how extensively it was being used throughout the country," claims Mueller. After conversations at the technical conference, he states, "It rapidly went from being just a concern in Illinois to ending up being a national and worldwide concern."

A machine called a dynamic shear rheometer (DSR) was presented to the industry throughout the Strategic Highway Research study Program's study task, which ranged from 1987 to 1992. The DSR is now the industry criterion for determining the viscoelastic homes of paving asphalt. Nonetheless, the device was not developed for the paving sector.


As an example, the DSR makes it possible for product developers to develop tooth paste with the best consistency to make sure that it can be pressed from a tube yet not fall off the tooth brush. The DSR examinations binder placed in between 2 parallel plates concerning the size of a quarter. Among the plates relocations and the device gauges the viscoelastic residential properties of the asphalt.
