"No one knew this product was being added to asphalt, had seen any kind of research study on exactly how this might influence performance of hot-mix asphalt sidewalks, or understood for exactly how lengthy and exactly how widely it was being used throughout the nation," says Mueller. After conversations at the technological conference, he states, "It quickly went from being just a problem in Illinois to coming to be a nationwide and worldwide concern."
