The fiberglass geogrid is a mesh structure material made of glass fiber and a certain weaving process. In order to protect the glass fiber and improve the overall performance, it is a geocomposite material made by a special coating process.
The main components of glass fiber are: silicon oxide, an inorganic material, its physical and chemical properties are extremely stable, and have high strength, high modulus, high wear resistance and excellent cold resistance, no long-term creep; thermal stability Good performance, because the surface is coated with special modified asphalt, it has double composite performance, which greatly improves the abrasion resistance and shearing ability of the geogrid.
Sometimes combined with self-adhesive pressure sensitive adhesive and surface asphalt impregnation treatment, the grille and the asphalt pavement are closely integrated into one. As the interlocking force of soil and rock materials in the geogrid grid increases, the friction coefficient between them increases significantly (up to 08~10). The frictional bite force is stronger and significantly increased, so it is a good reinforced material. At the same time, the geogrid is a kind of plastic flat mesh material with light weight and certain flexibility, which is easy to cut and connect on site, and can also be overlapped and overlapped. The construction is simple and does not require special construction machinery and professional technicians.
Features
1) High tensile strength, low elongation--fiberglass geogrid is made of glass fiber, which has high resistance to deformation, and the elongation at break is less than 3%.
2) No long-term creep--As a reinforcing material, it is extremely important to have the ability to resist deformation under a long-term load, that is, creep resistance. The glass fiber will not creep, which ensures that the product can maintain long-term performance.
3) Thermal stability-the melting temperature of the glass fiber is above 1000 ℃, which ensures the thermal stability of the glass fiber geogrid during the paving operation.
4) Compatibility with bitumen mixing--The material coated in the post-treatment process of the glass fiber geogrid is designed for the bituminous mixture. Each fiber is fully coated and has a high compatibility with bitumen. Therefore, it is ensured that the glass fiber geogrid will not be isolated from the asphalt mixture in the asphalt layer, but will be firmly combined.
5) Physical and chemical stability-after coating with a special post-treatment agent, the glass fiber geogrid can resist all kinds of physical abrasion and chemical erosion, as well as resist biological erosion and climate change, and ensure that its performance is not affected.
