The supplier denied adding PPA, but decreased to expose what had actually been contributed to the binder. When pressed by the division of transport, the vendor exposed that it was including what it called an asphalt extendernow recognized to be re-refined engine oil bases (REOB). REOB consists of a percentage of phosphorus, which is what department chemists originally determined.


"No one understood this material get more was being included to asphalt, had actually seen any type of research on how this might influence performance of hot-mix asphalt pavements, or recognized for how much time and exactly how widely it was being used throughout the country," states Mueller. After conversations at the technical conference, he states, "It rapidly went from being just a problem in Illinois to becoming a nationwide and worldwide concern."

The DSR is now the market requirement for gauging the viscoelastic homes of paving asphalt. The equipment was not developed for the paving industry (https://medium.com/@a1asphaltsealng/about).


For instance, the DSR makes it possible for product programmers to develop toothpaste with the best uniformity to make sure that it can be squeezed from a tube but not fall off the toothbrush.
