Glass fiber geogrid


The glass fiber geogrid is a geo-composite material made of glass fiber and made of a certain weaving process. It is a geocomposite material which is protected by glass fiber and improves the overall performance. The main component of glass fiber is: silicon oxide, which is an inorganic material. Its physical and chemical properties are extremely stable, and it has high strength, high modulus, high wear resistance and excellent cold resistance, no long-term creep; thermal stability. Good property; the mesh structure makes the aggregate interlock and limit; improve the load-bearing capacity of the asphalt mixture. Because the surface is coated with special modified asphalt, it has two-fold composite performance, which greatly improves the wear resistance and shearing capacity of the geogrid.


Sometimes combined with self-adhesive pressure-sensitive adhesive and surface asphalt impregnation, the grid and asphalt pavement are tightly integrated into one. Due to the increased interlocking force of the earth and stone in the geogrid grid, the friction coefficient between them increases significantly (up to 08 to 10), and the pull-out force of the geogrid embedded in the soil is due to the gap between the grid and the soil. The frictional bite force is stronger and significantly increased, so it is a good reinforcement material. At the same time, the geogrid is a kind of plastic flat net material with light weight and certain flexibility. It is easy to cut and connect on site, and can also overlap and overlap. It is easy to construct and does not require special construction machinery and professional technicians.


Features of fiberglass geogrid:


  • High tensile strength and low elongation - Glass fiber geogrid is made of glass fiber and has high resistance to deformation. The elongation at break is less than 3%.


  • No long-term creep – as a reinforcing material, it is extremely important to have the ability to resist deformation under long-term load, ie creep resistance. Glass fiber does not creep, which guarantees long-term performance.


  • Thermal stability - glass fiber melting temperature above 1000 ° C, which ensures that the fiberglass geogrid is subjected to thermal stability during paving operations.


  • Compatibility with Asphalt - Fiberglass Geogrid The material applied in the post-treatment process is designed for asphalt mixtures. Each fiber is fully coated and has high compatibility with asphalt. This ensures that the fiberglass geogrid does not become isolated from the asphalt mixture in the asphalt layer, but is firmly bonded together.


  • Physicochemical stability - coated with a special post-treatment agent, the fiberglass geogrid is resistant to all types of physical and chemical attack, as well as resists bio-erosion and climate change, ensuring that its performance is not affected.


Aggregate interlocking and restriction - Since the fiberglass geogrid is a mesh structure, the aggregate in the asphalt concrete can penetrate through it, thus forming a mechanical interlock. This limitation hinders the movement of the aggregate, enabling the asphalt mixture to achieve a better compaction condition under load, higher load bearing capacity, better load transfer performance and less deformation.
