The vendor refuted including PPA, yet decreased to expose what had been contributed to the binder. When pushed by the division of transport, the vendor revealed that it was adding what it called an asphalt extendernow known to be re-refined engine oil bases (REOB). REOB has a percentage of phosphorus, which is what division chemists initially determined.

"No one recognized this material was being contributed to asphalt, had seen any study on exactly how this may affect efficiency of hot-mix asphalt sidewalks, or understood for how much time and exactly how widely it was being made use of throughout the nation," states Mueller. After conversations at the technical meeting, he claims, "It swiftly went from being just a problem in Illinois to becoming a nationwide and worldwide problem."

For instance, the DSR makes it possible for product developers to produce toothpaste with the appropriate consistency to make sure that it can be pressed from a tube yet not drop off the toothbrush. The DSR tests binder positioned between 2 parallel plates regarding the size of a quarter. Among the plates moves and the machine gauges the viscoelastic residential or commercial properties of the asphalt.
