The vendor denied including PPA, yet decreased to expose what had been contributed to the binder. When pressed by the department of transportation, the vendor disclosed that it was adding what it called an asphalt extendernow understood to be re-refined engine oil bottoms (REOB). REOB contains a percentage of phosphorus, which is what division drug stores originally identified.


"No person understood this material was being contributed to asphalt, had seen any study on exactly how this might influence performance of hot-mix asphalt pavements, or recognized for the length of time and just how widely it was being made use of throughout the country," says Mueller. After conversations at the technical conference, he claims, "It promptly went from being simply a concern in Illinois to becoming a national and international concern."

A machine called a vibrant shear rheometer (DSR) was presented to the market during the Strategic Freeway Research study Program's research study project, which ranged from 1987 to 1992. The DSR is now the market standard for determining the viscoelastic residential properties of leading asphalt. Nevertheless, the device was not developed for the paving industry.


The DSR makes it possible for item designers to create tooth paste with the ideal uniformity so that it can be squeezed from a tube but not fall off the toothbrush. The DSR tests binder positioned between two identical plates concerning the dimension of a quarter. One of the plates moves and the machine measures the viscoelastic properties of the asphalt.
