The vendor rejected adding PPA, but declined to disclose what had been added to the binder. When pressed by the division of transportation, the supplier disclosed that it was including what it called an asphalt extendernow recognized to be re-refined engine oil bases (REOB). REOB consists of a percentage of phosphorus, which is what department chemists originally recognized.


"No person understood this material was being added to asphalt, had actually seen any type of research study on how this might influence efficiency of hot-mix asphalt pavements, or knew for for how long and how widely it was being made use of throughout the nation," says Mueller. After conversations at the technological meeting, he claims, "It promptly went from being just an issue in Illinois to ending up being a national and global problem."

A maker called a dynamic shear rheometer (DSR) was presented to the market during the Strategic Freeway Study Program's research job, which ranged from 1987 to 1992. The DSR is now the sector criterion for determining the viscoelastic properties of paving asphalt. Nevertheless, the device was not developed for the paving sector.


The DSR enables item programmers to develop toothpaste with the right consistency so that it can be pressed from a tube yet not drop off the tooth brush. The DSR tests binder placed in between 2 identical plates regarding the size of a quarter. Among the plates relocations and the machine gauges the viscoelastic properties of the asphalt.
