"Nobody understood this material was being included in asphalt, had seen any type of research on just how this may impact performance of hot-mix asphalt sidewalks, or understood for for how long and just how extensively it was being made use of throughout the country," claims Mueller. After discussions at the technical conference, he states, "It rapidly went from being just an issue in Illinois to coming to be a nationwide and international problem." Component of the mission of the Chemistry Research Laboratory at TFHRC is to establish brand-new test approaches.
