The vendor denied adding PPA, but declined to reveal what had been included in 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 bottoms (REOB). REOB includes a percentage of phosphorus, which is what division chemists originally determined.


"No person understood this material was being added to asphalt, had actually seen any type of research on exactly how this could impact efficiency of hot-mix asphalt sidewalks, or recognized for how much time and just how widely it was being made use of throughout the nation," says Mueller.

The DSR enables item programmers to produce toothpaste with the best consistency so that it can be pressed from a tube but not drop off the toothbrush. The DSR examinations binder positioned in between two parallel plates regarding the size of a quarter. Among home plates steps and the equipment measures the viscoelastic buildings of the asphalt.
