RAP currently has asphalt, albeit aged material that does not have the same homes of fresh asphalt.

The supplier denied including PPA, yet declined to reveal what had actually been added to the binder. When pressed by the department of transportation, the vendor exposed that it was adding what it called an asphalt extendernow known to be re-refined engine oil bottoms (REOB). REOB includes a small quantity of phosphorus, which is what department drug stores at first recognized.


"Nobody knew this product was being included to asphalt, had seen any research on exactly how this could influence performance of hot-mix asphalt sidewalks, or recognized for how lengthy and how widely it was being made additional reading use of throughout the nation," states Mueller. After discussions at the technological conference, he says, "It rapidly went from being just a problem in Illinois to becoming a national and international issue."

A machine called a vibrant shear rheometer (DSR) was introduced to the industry during the Strategic Highway Research Program's research task, which ranged from 1987 to 1992. The DSR is currently the market criterion for determining the viscoelastic properties of leading asphalt. Nevertheless, the machine was not created for the paving market.


The DSR allows product developers to develop toothpaste with the best consistency so that it can be squeezed from a tube but not drop off the tooth brush. The DSR tests binder positioned between two identical plates regarding the dimension of a quarter. One of home plates moves and the machine gauges the viscoelastic homes of the asphalt.
