REOB consists of a small amount of phosphorus, which is what division drug stores at first recognized.


"No person knew this product was being contributed to asphalt, had seen any kind of research study on just how this may impact performance of hot-mix asphalt sidewalks, or understood for how much time and how visit here widely it was being used throughout the nation," claims Mueller. After conversations at the technological conference, he states, "It rapidly went from being simply an issue in Illinois to ending up being a nationwide and international issue."
