When pushed by the department of transport, the vendor revealed that it was including what it called an asphalt extendernow known to be re-refined engine oil bases (REOB). REOB consists of a tiny quantity of phosphorus, which is what division chemists initially determined.


"No person recognized this product was being added to asphalt, had seen any type of research on how this important link could impact efficiency of hot-mix asphalt pavements, or recognized for for how long and just how widely it was being made use of throughout the country," claims Mueller. After discussions at the technological conference, he states, "It quickly went from being simply an issue in Illinois to coming to be a national and international concern."

A device called a dynamic shear rheometer (DSR) was presented to the market during the Strategic Highway Research Program's research project, which ranged from 1987 to 1992.

The equipment was not established for the paving industry (https://www.huntingnet.com/forum/members/a1asphaltseal.html).


The DSR makes it possible for item designers to develop tooth paste with the best consistency so that it can be pressed from a tube yet not drop off the toothbrush.
