REOB consists of a percentage of phosphorus, which is what department drug stores originally recognized.


"Nobody knew this product was being included in asphalt, had seen any kind of study on how this might influence efficiency of hot-mix asphalt pavements, or recognized for for how long and just how commonly it was being used throughout the nation," states Mueller. After discussions at the technological meeting, he says, "It promptly went from being just an issue in Illinois to becoming a nationwide and global issue."

For example, the DSR enables product designers to develop tooth paste with the best consistency so that it can be pressed from a tube but not diminish the tooth brush. The DSR tests binder put between 2 parallel plates concerning the dimension of a quarter. Among home plates actions and the maker measures the viscoelastic residential or commercial properties of the asphalt.
