REOB consists of a small quantity of phosphorus, which is what division chemists initially determined.


"No one understood this product was being contributed to asphalt, had seen any kind of research study on how this could affect performance of hot-mix asphalt sidewalks, or knew for the length of time and exactly how commonly it was being made use of throughout the nation," claims Mueller. After discussions at the technical conference, he claims, "It swiftly went from being just a problem in Illinois to coming to be a nationwide and worldwide issue."
