"No person understood this material was being included in asphalt, had actually seen any type of study on how this might affect performance of hot-mix asphalt sidewalks, or knew for for how long and just how widely it was being utilized throughout the country," claims Mueller. After conversations at the technological meeting, he claims, "It promptly went from being simply a problem in Illinois to becoming a national and global issue."
