The supplier rejected including PPA, however decreased to disclose what had actually been added to the binder. When pressed by the division of transportation, the supplier exposed 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 chemists initially recognized.


"Nobody understood this material was being included in asphalt, had seen any kind of study on exactly how this could influence efficiency of hot-mix asphalt sidewalks, or understood for for how long and exactly how commonly it was being used throughout the country," claims Mueller. After conversations at the technological conference, he states, "It swiftly went from being simply a problem in Illinois to coming to be a national and worldwide concern."

For instance, the DSR enables product programmers to create tooth paste with the best consistency to make sure that it can be pressed from a tube but not drop off the tooth brush. The DSR tests binder positioned in between two identical plates about the Visit Your URL size of a quarter.
