The supplier denied adding PPA, yet decreased to reveal what had actually been added to the binder. When pressed by the department of transportation, the vendor disclosed that it was adding what it called an asphalt extendernow understood to be re-refined engine oil bases (REOB). REOB contains a small quantity of phosphorus, which is what division drug stores originally identified.


"No person knew this material was being contributed to asphalt, had seen any type of study on exactly how this could influence efficiency of hot-mix asphalt pavements, or recognized for the length of time and how widely it was being utilized throughout the country," claims Mueller.

The DSR makes it possible for product designers to develop tooth paste with the appropriate uniformity so that it can be squeezed from a tube however not drop off the toothbrush. The DSR examinations binder put between two identical plates regarding the dimension of a quarter. Among home plates steps and the equipment gauges the viscoelastic properties of the asphalt.
