The supplier rejected adding PPA, but declined to reveal what had been included in the binder. When pushed by the division of transportation, the supplier disclosed that it was including what it called an asphalt extendernow known to be re-refined engine oil bases (REOB). REOB consists of a small amount of phosphorus, which is what department drug stores initially determined.


"No one recognized this material was being contributed to asphalt, had seen any research study on just how this may affect performance of hot-mix asphalt pavements, or recognized for just how long and exactly how widely it was being made use of throughout the country," claims Mueller. After conversations at the technical conference, he claims, "It rapidly went from being simply an issue in Illinois to coming to be a national and worldwide worry."

A machine called a dynamic shear rheometer (DSR) was presented to the industry during the Strategic Freeway Study Program's study task, which ran from 1987 to 1992. The DSR is now the industry requirement for gauging the viscoelastic homes of leading asphalt. Nonetheless, the device was not developed for the paving sector.


The DSR allows item designers to develop tooth paste with the ideal uniformity so that it can be squeezed from a tube but not fall off the tooth brush. The DSR examinations binder placed between two identical plates about the size of a quarter. One of the plates actions and the machine measures the viscoelastic properties of the asphalt.
