When pressed by the department of transportation, the vendor disclosed that it was including what it called an asphalt extendernow known to be re-refined engine oil bottoms (REOB). REOB contains a percentage of phosphorus, which is what division drug stores originally recognized.


"Nobody knew this material was being contributed to asphalt, had actually seen any kind of study on just how this could impact performance of hot-mix asphalt pavements, or recognized for how much time and exactly how commonly it was being used throughout the nation," claims Mueller. After discussions at the technical conference, he claims, "It rapidly went from being simply an issue in Illinois to coming to be a national and global problem."

For example, the DSR allows item programmers to develop toothpaste with the right consistency to ensure that it can be squeezed from a tube but not fall off the toothbrush. The DSR tests binder imp source positioned between 2 identical plates about the dimension of a quarter. One of the plates moves and the device measures the viscoelastic residential properties of the asphalt.
