Fiberglass geogridThe use of reinforced alkali free glass fiber yarn, advanced warp knitting machine weaving into the substrate, and the use of warp knitting directional structure, fully utilize the strength of the yarn in the fabric to improve its mechanical properties, making it have good tensile strength, tear strength, and creep resistance. It is a planar network material coated with modified asphalt, so the price of glass fiber geogrid is not cheap. It follows the principle of similarity and compatibility, and its composite performance with asphalt mixture fully protects the fiberglass substrate, improving its wear resistance and shear resistance. Therefore, it can be used for road surface reinforcement to resist road diseases such as cracks and ruts.

The reconstruction of cement concrete pavement into a composite pavement, the shortening of slabs, and other causes of reflection cracks, as well as the expansion and renovation of the road to prevent the formation of cracks due to uneven settlement at the ministerial level in the combination of new and old roads; It can enhance and reinforce the road surface, avoid rutting cracks, thermal and cold elastic cracks, and reflection cracks below, and can reduce the bearing stress of the road surface, extending the service life of the road surface; The reinforcement treatment of soft soil foundation is conducive to the consolidation of soft soil due to water separation, effective settlement, uniform stress distribution, and enhanced overall strength of the roadbed; Shortening cracks occur in the semi rigid base layer of the newly built road, and reinforcement is added to avoid road surface cracks caused by crack reflection.

Glass fiber geogrid has high modulus, light weight, good toughness, corrosion resistance, long service life, high tensile strength, low elongation, good physical chemical stability, good thermal stability, fatigue cracking resistance, high temperature rutting resistance, low temperature shrinkage cracking resistance, and delayed reduction of reflection cracks. It can be widely used in engineering fields such as the maintenance of old cement pavements, airport runways, embankments, riverbanks, slope protection, road bridge pavement reinforcement treatment, etc. Old asphalt concrete pavement, reinforced asphalt surface layer.
The warp knitted bidirectional geogrid applied on asphalt pavement is generally a glass fiber reinforced warp knitted bidirectional geogrid, and reflection cracks are a common disease phenomenon in asphalt pavement. Based on the practice of road engineering at home and abroad, in order to prevent reflection cracks on the road surface, a layer of glass fiber bidirectional geogrid is laid between the asphalt surface layer and the underlying layer, which can slow down the occurrence of surface reflection cracks, reduce the number of road repairs, and extend the use of the road.
