"No person recognized this material was being included to asphalt, had seen any research on exactly how this might affect performance of hot-mix asphalt pavements, or knew for the length of time and just how commonly it was being utilized throughout the country," says Mueller. After conversations at the technological conference, he states, "It swiftly went from being simply a problem in Illinois to ending up being a nationwide and worldwide worry."
