Glass fiber geogrid is an excellent geosynthetic material used for road reinforcement, road repair, and the strengthening of subgrade and soft soil foundations. It has become an indispensable material in the treatment of asphalt pavement reflective cracks. Made with reinforced alkali-free glass fiber yarn, utilizing advanced warp knitting machines from abroad to weave the base material, it features warp-knitted directional structures, fully utilizing the strength of the yarns within the fabric to enhance its mechanical properties. This results in excellent tensile strength, tear resistance, and creep resistance, and is a flat network material coated with superior modified asphalt. It boasts high tensile strength in both warp and weft directions with low elongation, and has characteristics such as 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 and cold expansion cracks, and reflective cracks below, and can disperse pavement bearing stress, extend pavement service life, and has high tensile strength with low elongation, no long-term creep, good physical and chemical stability, good thermal stability, resistance to fatigue cracking, heat-resistant rutting, cold-resistant cracking, and delayed reduction of reflective cracks.
