The fiberglass geogrid (TGS) of high-strength E-glass fiber {{glass fiber (English formerly known as: glass fiber or fiberglass) is a performance inorganic non-metallic materials, and variety, the advantages of good insulation, heat strong, good corrosion resistance, high mechanical strength, but the drawback is brittle, poor wear resistance. It is based on glass ball or discarded glass as raw material manufactured by high temperature melting, brushed, yarn, weaving and other crafts, monofilament diameter of a few microns to 20 meters micrometers, the equivalent of a hair of 1/20-1/5, each beam fiber precursor by hundreds of root or even thousands of root monofilament. Glass fibers are generally used as a reinforcing material in the composite material, an electrically insulating material and the insulation material, the circuit substrate or the like in various fields of the national economy. }} Mesh substrate coated handle made of semi-rigid products made of warp knitting process. For pavement enhanced reinforcing the old road, excellent geosynthetics reinforced roadbed and soft soil base. Types: double warp double weft single warp and single weft, warp-weft four after four-wai. Glassgrid widely used in asphalt pavement, cement pavement and subgrade enhanced and the railway embankment, dams, slope protection, airport runways, anti-desertification projects. Has reinforced the role of Glassgrid products have high strength, low elongation, high temperature, high modulus, light weight, good toughness, corrosion resistance, long life and other characteristics of products have high strength, low elongation, Usage: high temperature, light weight, good toughness, corrosion resistance, long life and other characteristics Glassgrid old asphalt pavement, reinforced enhanced asphalt surface, prevention and treatment of disease. Old asphalt pavement maintenance and upkeep of the road after a period of use, fatigue, the pavement would render cracking, loose, and the phenomenon of aging and wear. If not timely maintenance treatment, damaged road surface by surface water erosion will primary soft shells, the decline in the overall strength of the pavement, resulting in the destruction of the road. Emulsified asphalt slurry seal will make the old pavement Huanran to new, waterproof, skid, wear characteristics, and to repair the road surface is a good protective layer played a role extend the pavement life. Cement pavement converted composite pavement, inhibition of the plate contraction caused by the reflective cracking. Road Billiton improvement works at the prevention and treatment of old and new combination unit and uneven settlement caused cracks. 4. Soft soil foundation tendons processing, analysis of water consolidation in favor of soft soil, effectively inhibit the settlement, uniform stress distribution, enhanced roadbed overall strength. Shrinkage cracks, reinforced enhanced to prevent foundation cracks reflection caused cracks in the road. Construction method: the Glassgrid comes with a self-adhesive and without self-adhesive two, with self-adhesive is directly formed grassroots laying, without self-adhesive, usually using a nail fixed method. Glassgrid glass fiber material, the use of weaving mesh made of structural materials for the protection of glass fiber, to improve the overall use of performance geocomposite made through a special coating process. The main ingredients of the glass fibers is: silicon oxide, silicon is an inorganic material, and its physicochemical properties of highly stable and has a high strength, high modulus, high abrasion resistance and excellent cold, no long-term creep; thermal stability good; inserts lock and limitations of the network structure so that the aggregate; improve the load-bearing capacity of the asphalt mixture. Due to the surface coated with a special modified asphalt it has twofold composite performance, and greatly improves the abrasion resistance and the shear capacity of the geogrid. Sometimes with the self-adhesive Pressure Sensitive Adhesive and surface asphalt impregnated processing, grille and asphalt pavement closely integrated into one. Geogrid mesh soil, stone interlock force increased, the coefficient of friction between them was significantly increased (up to 08 to 10), the geogrid pullout resistance buried in the soil, due to the grille and soil stronger bite force of friction between the body and increases significantly, so it is a good reinforcement material. Geogrid is a quality of light, with some flexible plastic flat mesh material, easy on-site cutting and connection, also can overlap lap construction is simple, no special construction machinery and professional and technical personnel. The the fiberglass grille features: 1) high tensile strength, low elongation - fiberglass geogrid is glass fiber as raw material, has a high resistance to deformation, elongation at break of less than 3%. 2) long-term creep - creep does not occur as a reinforcing material, the ability to resist deformation in the case of long-term loads, the creep resistance is extremely important, glass fibers, this to ensure that the products can be long-term retention performance. 3) Thermal stability - the melting temperature of the glass fibers in the above 1000 ℃, which ensures that the fiberglass geogrid to withstand thermal stability in the paving operation. 4) mixed with asphalt compatibility - fiberglass geogrid coated materials in the post-treatment process for asphalt mixture design, each fiber is fully coated with asphalt has high compatibility ensuring fiberglass geogrid asphalt layer will not produce the asphalt mixture isolation, but rather a solid combination. 5) physical and chemical stability - through a special post-treatment agent coating processing, fiberglass geogrid can resist all kinds of physical wear and chemical attack, but also against biological erosion and climate change, to ensure that its performance will not be affected. 6) the aggregate embedded lock and limitations - fiberglass geogrid mesh structure, aggregate in asphalt concrete running through them, thus forming a mechanical interlocking. Such restrictions hinder the movement of aggregates, asphalt mixture to achieve better compaction in the case of load, higher load-bearing capacity, better load transfer performance and smaller deformation. Fiberglass grille engineering applications: fiberglass geogrid in recent years has developed rapidly and is widely used in the asphalt pavement, especially used in asphalt overlay layer to slow reflective cracking. Canada Texas AM University Traffic Institute with its unique overlay tester done a lot of the fiberglass geogrid reinforced overlay analog temperature cycle effects of fatigue test, the tests showed that the cracking resistance of reinforced asphalt specimen than unreinforced specimens more than twice. Australia New South Wales Wollongong City Council had fiberglass geogrid, polypropylene geogrids, geotextiles and thick asphalt concrete overlay layer control reflective cracking site comparative tests, concluded that fiberglass geogrid The convenient lay control reflective cracking is most significant, and moderate cost, and thus recommended that promote the use of.
