RAP already has asphalt, albeit aged product that does not have the same properties of fresh asphalt.

The vendor denied including PPA, yet decreased to disclose what had been included in the binder. When pushed by the division of transportation, the vendor disclosed that it was adding what it called an asphalt extendernow recognized to be re-refined engine oil bases (REOB). REOB includes a percentage of phosphorus, which is what division drug stores originally identified.


"No one knew this material was being contributed to asphalt, had actually seen any kind of study on exactly how this might influence efficiency of hot-mix asphalt sidewalks, or recognized for the length of time and exactly how commonly it was being used throughout the nation," states Mueller. After discussions at the technological conference, he states, "It rapidly went from being just a concern in Illinois to ending up being a national and global issue."

The DSR makes it possible for item developers to develop tooth paste with the best uniformity so that it can be pressed from a tube but not drop off the tooth brush. The DSR tests binder positioned between 2 parallel plates about the dimension of a quarter. One of the plates actions and the equipment gauges the viscoelastic buildings of the asphalt.
