Glass fiber geogrid is an excellent geosynthetic material used for road reinforcement, road repair, and the strengthening of subgrades and soft soil foundations. It has become an indispensable material in the treatment of asphalt pavement reflective cracks. Made from first-grade reinforced alkali-free glass fiber yarn, utilizing advanced warp-knitting machines from abroad to weave the base material, it employs a warp-knitted directional structure to fully utilize the strength of the yarns within the fabric, enhancing its mechanical properties. This results in excellent tensile strength, tear resistance, and creep resistance, and is coated with modified asphalt to form a flat network material. It boasts high tensile strength in both warp and weft directions with low elongation, and features high heat resistance, high modulus, light weight, good toughness, corrosion resistance, and long service life. It is widely applicable in the repair of old cement pavements, airport runways, embankments, riverbanks, slope protection, road and bridge pavement reinforcement, and other engineering fields. It can reinforce and repair pavements, prevent rutting fatigue cracks, thermal expansion and contraction cracks, and underlying reflective cracks, and can disperse pavement bearing stress, extend pavement service life, and has high tensile strength, low elongation, no long-term creep, good physical and chemical stability, good thermal stability, resistance to fatigue cracking, heat-resistant rutting, low-temperature shrinkage cracking resistance, and delayed reduction of reflective cracks.
