When pushed by the department of transportation, the supplier disclosed that it was adding what it called an asphalt extendernow understood to be re-refined engine oil bottoms (REOB). REOB contains a tiny quantity of phosphorus, which is what department chemists initially identified.


"No person recognized this material was being contributed to asphalt, had actually seen any type of study on just how this may impact performance of hot-mix asphalt pavements, or knew for how much time and how extensively it was being used throughout the country," states Mueller. After conversations at the technical conference, he states, "It quickly went from being simply a concern in Illinois to coming to be a national and global issue."

The DSR enables item designers to produce tooth paste with the ideal consistency so that it can be pressed from a tube yet not fall off the toothbrush.
