Geogrid of fiberglass
(1)Product introduction
Glass fiber grid is plane network shape material that selects excellent reinforcement non-alkali glass fiber yarn, is weaved into base material by using foreign advanced warp knitter, uses warp knitting directional structure, makes full use of yarn strength in textile, improves its chemical performance, makes 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 synthetio performance with asphalt mixture, protects glass fiber base material fully and improves 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 from occurring and to solve the problem that asphalt road surface is difficult for reinforcement.
(2)Product features
The product has high intensity the elongation ratio low, thermostable, the module is high, the weight is light, toughness good) anti-corrosive, life long and so on characteristics, and widely applies in the old cement road surface, runways service, the dike, the river bank, the side slope protection, project domains and so on road bridge connection surface dohancement processing, may give the road surface to strengthen, the reinforcement, prevents the road surface wheel rut fatigue crack, the hot cold expansion crack and the following reflection crack, and can be scattered the road surface bearing stress, the extension road surface service life, the high tensile strength low elongation ratio, no long-term slow change, the physical chemistry stability is good, the thermostability is good, the anti-weary dehiscence, thermostable wheel rut, anti-low temperature shrinkage crack. Postponement reduction reflection crack.
3application range
1. It reinforce old asphalt concrete road surface and asphalt surface layer, and prevents damage.
2. It is used for rebuilding cement concrete road surface into composite road surface and restraining reflection caused by block contraction.
3. Its used in road expansion and improvement project and prevents crack caused by old and new combination position and uneven sedimentation.
4. Its used in soft soil base reinforcement treatment, is favorable for soft soil water separation and concretion, restrains sedimentation effectively, distributes stress uniformly and improves overall strength of road base.
5. Its used for preventing contraction crack caused by new road semi-rigid base layer, and reinforces and prevents road surface crack caused by foundation crack reflection.
