Glass fiber geogrid for soil reinforcement

The glass fiber geogrid is a geosynthetic material made of glass fiber and made of a certain weaving process. It is a geocomposite material which is made of a special coating process to protect the glass fiber and improve 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 strong 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.

Glass fiber geogrid

1) 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%.

2) No long-term creep - As a reinforcing material, it is extremely important to have the ability to resist deformation under long-term load, that is, creep resistance, and the glass fiber does not creep, which ensures that the product can maintain performance for a long time.

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

4) Compatibility with asphalt – The material coated in the post-treatment process of the fiberglass geogrid is designed for the asphalt mixture. Each fiber is fully coated and highly compatible with asphalt. Sexuality ensures that the fiberglass geogrid does not become isolated from the asphalt mixture in the asphalt layer, but is firmly bonded together.

5) Physicochemical stability - After special coating treatment, the glass fiber geogrid can resist various physical and chemical erosion, and can resist bio-erosion and climate change to ensure its performance is not affected.

6) Aggregate interlocking and restriction - Since the fiberglass geogrid is a mesh structure, the aggregate in the asphalt concrete can penetrate therethrough, 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.
