The vendor denied including PPA, but decreased to reveal what had been included to the binder. When pushed by the division 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 contains a percentage of phosphorus, which is what division chemists initially recognized.


"No person recognized this material was being included to asphalt, had seen any study on exactly how this might affect efficiency of hot-mix asphalt pavements, or recognized for how much time and how extensively it was being utilized throughout the country," claims Mueller. After conversations at the technical conference, he states, "It quickly went from being simply a problem in Illinois to coming to be a national and international problem."

A machine called a dynamic shear rheometer (DSR) was presented to the sector during the Strategic Freeway Study Program's research task, which ranged from 1987 to 1992. The DSR is now the sector criterion for determining the viscoelastic properties of leading asphalt. The maker was not developed for the paving sector (https://truthful-heron-jjppp1.mystrikingly.com/blog/a1-professional-asphalt-repairs-paving-excellence-in-st-louis).


The DSR makes it possible for product programmers to create tooth paste with the best consistency so that it can be pressed from a tube but not drop off the tooth brush. The DSR tests binder put between two parallel plates concerning the dimension of a quarter. Among home plates relocations and the device measures the viscoelastic homes of the asphalt.
