Geogrid is a mesh structure material made of fiberglass and certain weaving techniques. In order to protect glass fibers and improve overall performance, geosynthetic materials are made using special coating processes. The main component of glass fiber is silicon oxide, an inorganic material with very stable physical and chemical properties, high strength, high modulus, high wear resistance, and excellent cold resistance, without long-term creep; Good thermal stability performance; The mesh structure enables the aggregate to be locked and restricted; It improves the bearing capacity of asphalt mixture. Due to the special modified asphalt coating on the surface, it has dual composite properties, greatly improving the wear resistance and shear capacity of the geogrid.
Sometimes, a combination of self-adhesive pressure-sensitive adhesive and surface asphalt impregnation treatment is used to tightly integrate the geogrid with the asphalt pavement. As the biting force of the soil and stone materials in the geogrid increases, the friction coefficient between them significantly increases. The pull-out resistance of geogrids buried in soil is due to the interlocking force between the grid and the soil. The friction and bite force are stronger and significantly increased, making it a good reinforcement material. Meanwhile, geogrid is a lightweight and flexible plastic mesh that is easy to cut and connect on site, and can also be stacked. Geogrid construction is simple and does not require special construction machinery or professional technicians.
Characteristics of geogrid:
1. High tensile strength, low elongation - The geogrid is made of glass fiber and has high deformation resistance, with a fracture elongation of less than 3%.
2. No long-term creep - as a reinforcing material, it is important to have the ability to resist deformation under long-term loads, that is, the ability to resist creep. Glass fiber will not creep, ensuring that the product can maintain its performance for a long time.
3. Thermal stability - The melting temperature of glass fiber is above 1000 ℃, ensuring the thermal stability of geogrids during paving operations.
4. Compatibility with Asphalt Mixtures - The material used for the post-treatment coating of geogrids is specifically designed for asphalt mixtures. Each fiber is coated and has high compatibility with asphalt. This ensures that the geogrid will not separate from the asphalt mixture in the asphalt layer, but will be firmly bonded together.
5. Physical and chemical stability - After being coated with special post-treatment agents, geogrids can resist various physical wear and chemical erosion, as well as biological erosion and climate change, ensuring their performance is not affected.
6. Interlocking and restraint of aggregates - Due to the mesh structure of geogrids, aggregates in asphalt concrete can pass through it, forming mechanical interlocking. This restriction hinders the movement of aggregates, allowing asphalt mixtures to achieve better compaction, higher bearing capacity, better load transfer performance, and smaller deformation under load.
