The supplier refuted adding PPA, however decreased to reveal what had actually been contributed to the binder. When pushed by the department of transport, the supplier exposed that it was including 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 division chemists at first identified.


"Nobody knew this product was being contributed to asphalt, had seen any kind of study on exactly how this might affect performance of hot-mix asphalt pavements, or recognized for for how long and exactly how widely it was being made use of throughout the nation," claims Mueller. After discussions at the technological conference, he says, "It swiftly went from being just a concern in Illinois to ending up being a national and international worry."

A device called a vibrant shear rheometer (DSR) was introduced to the industry throughout the Strategic Freeway Research Program's research project, which ranged from 1987 to 1992. The DSR is now the sector standard for determining the viscoelastic properties of paving asphalt. However, the equipment was not created for the paving industry.


For instance, the DSR allows item developers to produce tooth paste with the ideal uniformity to make sure that it can be squeezed from a tube however not diminish the tooth brush. The DSR tests binder placed between 2 parallel plates regarding the size of a quarter. One of home plates moves and the device determines the viscoelastic residential or commercial properties of the asphalt.
