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


"No person recognized this material was being included to asphalt, had actually seen any type of research on how this might influence efficiency of hot-mix asphalt pavements, or understood for how lengthy and how widely it was being used throughout the country," says Mueller. After discussions at the technological conference, he says, "It swiftly went from being simply an issue in Illinois to becoming a nationwide and international concern."

A machine called a dynamic shear rheometer (DSR) was presented to the sector during the Strategic Freeway Study Program's research study project, which ranged from 1987 to 1992. The DSR is now the sector requirement for gauging the viscoelastic homes of paving asphalt. Nevertheless, the maker was not created for the paving sector.


For example, the DSR enables item programmers to create toothpaste with the appropriate uniformity to ensure that it can be squeezed from a tube but not fall off the toothbrush. The DSR tests binder put between two parallel plates about the size of a quarter. One of home plates actions and the machine gauges the viscoelastic residential or commercial properties of the asphalt.
