The GlasGrid Pavement Reinforcement System, manufactured by ADFORS-St. Gobain and distributed by Tensar, is a pavement interlayer that resists the migration of reflective cracks in an asphalt overlay. When the GlasGrid System is “sandwiched” between the leveling and surface course asphalt in a conventional asphalt overlay, it turns vertical crack stresses horizontally to effectively dissipate them. And with GlasGrid Tack Film (TF), you can reap all of the benefits of the GlasGrid System without dealing with the challenges of a conventional tack coat.
