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


"No one knew this material was being included to asphalt, had seen any research study on just how this might affect performance of hot-mix asphalt sidewalks, or recognized for how much time and just how extensively it was being made use of throughout the nation," claims Mueller. After conversations at the technical meeting, he claims, "It rapidly went from being just a concern in Illinois to ending up being a national and global issue."
