The vendor rejected including PPA, yet decreased to disclose what had actually been included in the binder. When pressed by the department of transportation, the supplier disclosed that it was including what it called an asphalt extendernow known to be re-refined engine oil bottoms (REOB).

"No person recognized this product was being included to asphalt, had seen any type of research on how this might impact performance of hot-mix asphalt sidewalks, or recognized for the length of time and exactly how widely it was being used throughout the nation," claims Mueller.

The device was not created for the paving sector (https://www.imdb.com/user/ur180438932/).


For instance, the DSR allows item designers to develop tooth paste with the best uniformity to ensure that it can be pressed from a tube however not drop off the toothbrush. The DSR tests binder put in between two parallel plates about the size of a quarter. One of the plates moves and the equipment gauges the viscoelastic buildings of the asphalt.
