Geogrid of fiberglass is plane network shape material that selects excellent reinforcement non-alkali roving ,is weaved into base material by using foreign advanced warp knitter,uses warp knitting directional structure, make full use of yarn strength in textile, improve its chemical performance, make it have good tension resistance, tearing resistance and creep resistance and is formed by excellent modified asphalt coating treatment. It follows similar and compatible principle, lays stress on its synthetic performance with asphalt mixture, protects glass fiber base material fully and improve wearing resistance and shearing force resistance of base material so as to make road surface reinforce, to prevent highway harm such as crack and rut form occuring and to solve the problem that asphalt road surface is difficult for reinforcement.
