Fiberglass grating is a semi - rigid product made by coating a non - alkali glass fiber scrim as the base material. It is a new type of excellent geotechnical base material for enhancing the function of road surfaces. Fiberglass grating is made by interweaving glass fibers and casting resin through overall molding.

1. The full penetration of the interwoven glass fibers and resin makes the grating highly corrosion - resistant.

2. The overall structure of the grating evenly distributes the load, which helps the grating and its supporting structure to bear the load evenly.

3. The glossy surface and inclined grid surface of the grating give it a self - cleaning function.

4. The concave surface on the surface of the grating gives it an anti - slip function, and the anti - slip effect is better when the sand - covered surface is paved.

The main component of glass fiber is silicate, which is a material with extremely stable physical and chemical properties. It has high heat resistance and excellent cold resistance (the general working temperature is - 100 - 280°C), high strength, high modulus, good chemical stability, corrosion resistance, low expansion coefficient, and good dimensional stability. After surface modification and coating treatment, the surface properties of the glass fiber are changed, its composite performance with asphalt is improved, and the wear resistance and shear resistance of this base material are greatly improved.

1) High tensile strength and low elongation - fiberglass grating is made of glass fiber as the material, and the strength of glass fiber is relatively high, exceeding that of other fibers and metals. At the same time, its modulus is very high, and it has a high anti - deformation ability, with a fracture elongation of less than 3%.

2) No long - term creep - As a reinforcing material, it is extremely important for fiberglass grating to have the ability to resist deformation under long - term loads, that is, creep resistance. Glass fiber will not creep, which ensures that the product can maintain its performance for a long time.

3) Thermal stability - The melting temperature of glass fiber is above 1000°C, which ensures the thermal stability of fiberglass grating during the paving operation.

4) Compatibility with asphalt mixture - The material coated in the post - treatment process of fiberglass grating is designed for asphalt mixture. Each fiber is fully coated and has a high compatibility with asphalt, thus ensuring that the fiberglass grating will not be isolated from the asphalt mixture in the asphalt layer, but will be firmly combined together.

5) Physical and chemical stability - After being coated with special post - treatment agents, the fiberglass geogrid can resist various physical abrasions, chemical corrosions, biological corrosions and climate changes, ensuring that its performance is not affected.

6) Aggregate interlocking and bundling - Since fiberglass grating is a mesh structure, aggregates in asphalt concrete can penetrate through it, thus forming mechanical interlocking. This bundling prevents the movement of aggregates, enabling the asphalt mixture to reach a better compaction state, higher load - bearing capacity, better load - transfer function and smaller deformation under load.
