The supplier rejected including PPA, yet decreased to reveal what had been contributed to the binder. When pressed by the department of transportation, the vendor revealed that it was including what it called an asphalt extendernow understood to be re-refined engine oil bottoms (REOB). REOB contains a small amount of phosphorus, which is what department chemists originally recognized.


"Nobody understood this product was being included in asphalt, had actually seen any kind of research study on exactly how this could influence performance of hot-mix asphalt sidewalks, or understood for for how long and how commonly it was being used throughout the nation," states Mueller. After discussions at the technical conference, he says, "It promptly went from being just a concern in Illinois to ending up being a national and worldwide worry."

The DSR allows item developers to develop tooth paste with the right uniformity so that it can be squeezed from a tube but not fall off the toothbrush. The DSR tests binder positioned in between two identical plates concerning the size of a quarter. Among the plates steps and the device gauges the viscoelastic residential or commercial properties of the asphalt.
