How does fiberglass grating prevent road reflection cracks?

Fiberglass grating is an important geosynthetic material. Compared with other geosynthetics, it has the same properties and effects. Fiberglass grating is often used as a reinforcing material for reinforced soil structures or a reinforcing material for composite materials.

Application characteristics of glass fiber geogrid:
1. Fiberglass grating is mainly used for soft foundation disposal, roadbed reinforcement, slope protection, bridge abutment reinforcement, wing wall, retaining wall, isolation and reinforced soil engineering on highways.
2. The use of fiberglass gratings on railways can prevent premature settlement and destruction of railways on soft soil foundations.
3. Fiberglass grating is used in water conservancy projects such as embankments, dams, rivers, canals, sea embankments, and reservoir reinforcement.
4. Strengthening the airport foundation with fiberglass grating can greatly improve the bearing capacity of the runway and ensure the safety of aircraft takeoff and landing.
5. Fiberglass grating can be used in slag site disposal, power plants, ash dam projects, coal mines, metallurgy, greening, fences and other fields.
6. Fiberglass grating can be used to reinforce the soft foundation of building structures and improve the overall bearing capacity of the foundation.

 In order to solve the problem of reflection cracks caused by the transformation of rigid pavement into flexible pavement, the performance of glass fiber grating is generally used in the design of highway reconstruction projects. Thereby increasing the service life of the road surface. Fiberglass geogrid is a geocomposite material made of glass fiber through a special coating process. The main components of glass fiber are: silicon oxide, which is an inorganic material. Its physical and chemical properties are extremely stable, and it has high strength, high modulus, no long-term creep, good wear resistance and thermal stability. Because the surface is coated with special modified asphalt, it has dual composite properties, which greatly improves the wear resistance and shear capacity of the geogrid. Glass fiber geogrid is made of glass fiber, which has high resistance to deformation, and the elongation at break is less than 3%. As a reinforcing material, it is extremely important to have the ability to resist deformation under long-term load, that is, creep resistance. Glass fiber does not creep, which ensures that the product can maintain its performance for a long time. Since the melting temperature of glass fiber is above 1000°C, this ensures that the glass fiber geogrid can withstand higher temperatures during the paving operation and has good thermal stability. The material coated by the glass fiber geogrid in the post-treatment process is designed for the asphalt mixture, and each fiber is fully coated, which has a high compatibility with the asphalt, thus ensuring that the glass fiber geogrid can be The asphalt layer will not be isolated from the asphalt mixture, but will be firmly combined. After being coated with a special post-treatment agent, the glass fiber geogrid can resist various physical wear and chemical erosion, as well as resist biological erosion and climate change, ensuring that its performance is not affected.
