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 revealed that it was including what it called an asphalt extendernow recognized to be re-refined engine oil bases (REOB). REOB includes a small amount of phosphorus, which is what division drug stores at first identified.


"No one recognized this product was being included in asphalt, had actually seen any type of research study on just how this may impact efficiency of hot-mix asphalt sidewalks, or knew for for how long and just how commonly it was being used throughout the nation," states Mueller.

The DSR allows item designers to produce toothpaste with the appropriate uniformity so that it can be squeezed from a tube however not fall off the toothbrush. The DSR examinations binder put between two identical plates regarding the size of a quarter. Among the plates moves and the machine determines the viscoelastic buildings of the asphalt.
