The vendor denied including PPA, however declined to expose what had actually been included to the binder. When pushed by the division of transport, the vendor disclosed that it was including what it called an asphalt extendernow known to be re-refined engine oil bottoms (REOB). REOB includes a percentage of phosphorus, which is what department chemists initially determined.


"No person understood try this out this material was being contributed to asphalt, had seen any study on how this might affect performance of hot-mix asphalt sidewalks, or understood for for how long and exactly how widely it was being utilized throughout the nation," claims Mueller. After discussions at the technical meeting, he claims, "It swiftly went from being simply a problem in Illinois to ending up being a nationwide and global worry."

A maker called a dynamic shear rheometer (DSR) was presented to the market throughout the Strategic Highway Study Program's study project, which ran from 1987 to 1992. The DSR is now the industry requirement for gauging the viscoelastic properties of leading asphalt. Nevertheless, the maker was not created for the paving industry.


The DSR allows item designers to develop toothpaste with the best consistency so that it can be squeezed from a tube but not drop off the toothbrush. The DSR tests binder put in between two parallel plates about the size of a quarter. One of the plates steps and the device measures the viscoelastic properties of the asphalt.
