The fiberglass geogrid is made of fiberglass filaments woven and coated

1. Overview of glass fiber geogrid

Glass fiber geogrid is an excellent geosynthetic material used for pavement reinforcement, old road reinforcement, subgrade and soft soil foundation. It is a semi-rigid product made of high-strength alkali-free glass fiber through international advanced warp knitting technology to make a mesh base material, and then surface coating treatment. It is made of glass fiber filaments by knitting and coating.

2. Characteristics of glass fiber geogrid

（1) Mechanical properties

• High tensile strength, low elongation: With glass fiber as raw material, it has high deformation resistance, and the elongation at break is less than 3%, which makes it not easy to be elongated and deformed when bearing external forces.
• No long-term creep: As a reinforcement material, it can resist deformation under long-term load, and the glass fiber will not creep, which can ensure the long-term performance of the product.
• High modulus of elasticity: It has a high modulus of elasticity and can effectively resist deformation when stressed, such as bearing certain stresses in pavement structures and maintaining structural stability.

（2) Temperature adaptability

Good thermal stability: the melting temperature of glass fiber is 1000 ℃The above ensures the stability of the glass fiber geogrid to withstand heat in high-temperature environments such as paving operations, and can also be used normally in severe cold areas, showing good high and low temperature resistance.

（3) Relationship with other materials

• Compatibility with asphalt mixing: The material applied in the post-treatment process is designed for the asphalt mixture, each fiber is fully coated and has a high compatibility with the asphalt, does not create isolation from the asphalt mixture in the asphalt layer, but is firmly bonded together.
• Aggregate interlocking and restriction: Its mesh structure allows the aggregate in asphalt concrete to penetrate through it, forming a mechanical interlocking. This kind of interlocking limits the movement of aggregate, allows the asphalt mixture to achieve a better compaction state when loaded, improves the load-bearing capacity, load transfer performance, and reduces deformation.

（4) Durability

• Physical and chemical stability: After coating with a special post-treatment agent, it can resist all kinds of physical wear and chemical erosion, as well as biological erosion and climate change, ensuring that its performance is not affected.
• Excellent alkali resistance and aging resistance: After surface coating treatment, it has good durability in different environments and can play a role for a long time.
