Fiberglass Geogrid is a kind of plane warp knitted mesh material with alkali-free fiberglass yarn as main body and then coated with bitumen, also called asphalt geogrid. Fiberglass Geogrid gives full protection for the fiberglass matrix and greatly improves the Biaxial Geogrid mesh retaining wall's wear and shear resistance. The most significant performance is the compound properties of the fiberglass yarn and asphalt mixture, which protects the fiberglass base material sufficiently and enhances its abrasive resistance and anti-shear ability. Thus the material is used for road surface reinforcement and resist crack and rut avoiding which solves the problem of hard-to-protect of asphalt pavement.
Fiberglass Geogrid has two kinds: normal one and the self-adhesive one:
For the self-adhesive type, there is a layer coating of self - pressure sensitive adhesive. Not only can keep the normal product's performance, but also ensure the Biaxial Geogrid Mesh Retaining Walls combine tightly with the contacting surface. Self-adhesive Fiberglass Geogrid has the features of construction convenient and paving leveling.

Application Range:
1.It reinforces old asphalt concrete road surface as well as asphalt 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.It is used in road expansion and improvement project, control cracks caused by old and new combination position or by uneven sedimentation;
4.It is used in soft soil base reinforcement treatment. It is favorable for soft soil water separation and concretion,restrains sedimentation effectively, distributes stress uniformly and improves overall strength of road base;
5.It is sued for preventing contraction crack caused by new road semi-rigid base layer, and reinforces and prevents road surface crack caused by foundation crack reflection.
