It has been made use of in leading for greater than a a century.


Today, however, it is an extremely traded asset that requires premium costs. These prices have boosted significantly. In 2002, asphalt sold for roughly $160 per ton.

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


"No person understood this material was being included in asphalt, had seen any study on just how this might influence efficiency of hot-mix asphalt sidewalks, or understood for how long and exactly how extensively it was being made use of throughout the nation," claims Mueller.

The DSR makes it possible for item developers to produce tooth paste with the right consistency so that it can be pressed from a tube yet not drop off the tooth brush. The DSR tests binder positioned between 2 parallel plates about the size of a quarter.
