REOB has a percentage of phosphorus, which is what department chemists initially identified.


"No one recognized this material was being included in asphalt, had actually seen any study on exactly how this might impact performance of hot-mix asphalt sidewalks, or understood for the length of time and how extensively it was being made use of throughout the country," states Mueller. After discussions at the technological conference, he states, "It promptly went from being just a concern in Illinois to becoming a national and international problem."

A machine called a dynamic shear rheometer (DSR) was presented to the sector throughout the Strategic Freeway Study Program's research study project, which ran from 1987 to 1992.

The DSR allows product programmers to develop tooth paste with the ideal consistency so that it can be pressed from a tube but not fall off the tooth brush. The DSR tests binder put between 2 identical plates regarding the size of a quarter. Among home plates moves and the machine determines the viscoelastic residential properties of the asphalt.
