REOB contains a percentage of phosphorus, which is what department chemists originally determined.


"No one knew this product was being included in asphalt, had seen any kind of research study on exactly how this might influence efficiency of hot-mix asphalt pavements, or recognized for for how long and just how extensively it was being utilized throughout the nation," states Mueller. After discussions at the technological meeting, he says, "It promptly went from being simply a problem in Illinois to ending up being a nationwide and global worry."

A machine called a vibrant shear rheometer (DSR) was presented to the sector throughout the Strategic Highway Research study Program's research task, which ran from 1987 to 1992.
