NCAT study praises ground tire rubber for asphalt applications

摘要

The National Center for Asphalt Technology (www.ncat.us), Auburn, AL, announced the results of a study evaluating the role of ground tire rubber powder in asphalt mixture performance. Debunking a common industry belief, the study indicates that the asphalt manufacturing process, whether cryogenic or ambient, does not impact the performance of the rubber material or, ultimately, the asphalt.
