REOB contains a percentage of phosphorus, which is what division drug stores originally determined.


"No one understood this material was being included to asphalt, had seen any research on how this could impact efficiency of hot-mix asphalt pavements, or knew for for how long and exactly how commonly it was being made use of throughout the nation," says Mueller. After conversations at the technical conference, he states, "It quickly went from being simply a problem in Illinois to becoming a national and international worry."
