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


"No one recognized this material was being included in asphalt, had seen any kind of study on just how this could affect performance of hot-mix asphalt sidewalks, or understood for how much time and exactly how widely it was being used throughout the country," states Mueller. After conversations at the technical conference, he says, "It promptly went from being simply a problem in Illinois to becoming a nationwide and international concern." Part of the goal of the Chemistry Lab at TFHRC is to develop new examination methods.

A machine called a dynamic shear rheometer (DSR) was introduced to the industry throughout the Strategic Freeway Research study Program's research study project, which ran from 1987 to 1992. The DSR is currently the market requirement for determining the viscoelastic residential or commercial properties of paving asphalt. However, the maker was not established for the paving industry.


As an example, the DSR allows product designers to create tooth paste with the appropriate consistency to ensure that it can be squeezed from a tube however not diminish the toothbrush. The DSR tests binder put between 2 identical plates concerning the dimension of a quarter. One of the plates moves and the machine determines the viscoelastic residential or commercial properties of the asphalt.
