The supplier denied including PPA, but decreased to expose what had been included in the binder. When pressed by the department of transport, the supplier disclosed that it was including what it called an asphalt extendernow understood to be re-refined engine oil bottoms (REOB). REOB has a percentage of phosphorus, which is what division drug stores originally determined.


"No person knew this material was being contributed to asphalt, had actually seen any type of research study on how this might influence efficiency of hot-mix asphalt pavements, or understood for the length of time and exactly how extensively it was being utilized throughout the nation," says Mueller. After conversations at the technical conference, he claims, "It rapidly went from being just a concern in Illinois to ending up being a nationwide and global problem."

An equipment called a dynamic shear rheometer (DSR) was presented to the sector during the Strategic Freeway Study Program's study task, which ran from 1987 to 1992. The DSR is now the sector standard for gauging the viscoelastic residential or commercial properties of leading asphalt. The machine was not created for the paving sector (https://issuu.com/a1asphaltseal).


The DSR allows product designers to produce toothpaste with the appropriate uniformity so that it can be squeezed from a tube but not fall off the tooth brush. The DSR examinations binder put between 2 identical plates concerning the size of a quarter.
