The supplier refuted including PPA, but declined to disclose what had actually been contributed to the binder. When pressed by the division of transportation, the supplier revealed that it was including what it called an asphalt extendernow understood to be re-refined engine oil bottoms (REOB). REOB includes a percentage of phosphorus, which is what department chemists initially recognized.


"No person knew this material was being contributed to asphalt, had seen any kind of research on exactly how this could impact efficiency of hot-mix asphalt pavements, or knew for just how lengthy and exactly how widely it was being made use of throughout the nation," states Mueller. After discussions at the technological meeting, he says, "It quickly went from being just an issue in Illinois to ending up being a nationwide and worldwide worry."

A device called a vibrant shear rheometer (DSR) was presented to the sector during the Strategic Freeway Study Program's research study task, which ranged from 1987 to 1992. The DSR is currently the industry standard for gauging the viscoelastic residential or commercial properties of paving asphalt. The device was not developed for the paving sector (https://pastebin.com/u/a1asphaltseal).


The DSR allows product developers to develop tooth paste with the right consistency so that it can be pressed from a tube however not drop off the tooth brush. The DSR tests binder placed between two parallel plates about the dimension of a quarter. Among home plates relocations and the machine gauges the viscoelastic buildings of the asphalt.
