When pressed by the division of transport, the supplier find this disclosed that it was including what it called an asphalt extendernow recognized to be re-refined engine oil bottoms (REOB). REOB includes a percentage of phosphorus, which is what department chemists originally determined.


"Nobody knew this material was being included in asphalt, had actually seen any type of research on how this could affect performance of hot-mix asphalt sidewalks, or understood for the length of time and how widely it was being utilized throughout the nation," says Mueller. After conversations at the technical conference, he states, "It quickly went from being simply a problem in Illinois to coming to be a nationwide and global problem."

As an example, the DSR enables product programmers to produce toothpaste with the appropriate uniformity so that it can be squeezed from a tube however not fall off the toothbrush. The DSR tests binder put in between 2 identical plates about the dimension of a quarter. One of home plates relocations and the equipment gauges the viscoelastic homes of the asphalt.
