How does fiberglass grating prevent reflective cracks on road surfaces?

　　Glass fiber grating is a major geosynthetic material, which has common performance and effectiveness compared to other geosynthetic materials. Fiberglass grids are commonly used as reinforcement materials for reinforced soil structures or composite materials.

　　Application characteristics of geogrids:

　　1. Fiberglass gratings are mainly used for soft foundation treatment, roadbed reinforcement, slope protection, bridge abutment reinforcement, wing walls, retaining walls, isolation, and reinforced soil engineering on highways.

　　2. The use of fiberglass gratings on railways can prevent premature settlement and damage of railways on soft soil foundations.

　　3. Fiberglass grids are used in water conservancy projects such as embankments, dams, rivers, canals, seawall construction, and reservoir reinforcement.

　　4. Strengthening the airport foundation with fiberglass grating can greatly improve the load-bearing capacity of the runway and ensure safe takeoff and landing of aircraft.

　　5. Glass fiber grating can be used for disposal of waste sites, power plants, ash dam projects, coal mines, metallurgy, greening, fencing and other fields.

　　6. Glass fiber grating can be used for strengthening soft foundations in building construction, improving the overall bearing capacity of the foundation.

　　The performance of fiberglass grating is to solve the problem of reflection cracks caused by the transformation of rigid pavement into flexible pavement. Generally, in the design of highway renovation projects, the new geotechnical material fiberglass grating is used to suppress and delay the reflection cracks on asphalt concrete pavement, thereby improving the service life of the pavement.

　　Glass fiber geogrid is a geosynthetic composite material made of glass fiber through a special coating process.

　　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, no long-term creep, good wear resistance, and thermal stability.

　　Due to the special modified asphalt coating on its surface, it has dual composite properties, greatly improving the wear resistance and shear capacity of the geogrid.

　　Glass fiber geogrid is made of glass fiber and has high resistance to deformation, with a fracture elongation of less than 3%. As a reinforcing material, it is extremely important to have the ability to resist deformation under long-term loads, i.e. creep resistance. Glass fibers do not undergo creep, which ensures that the product can maintain performance for a long time.

　　Due to the melting temperature of fiberglass above 1000 ℃, this ensures that the fiberglass geogrid can withstand high temperatures and has good thermal stability during paving operations.

　　The material coated with fiberglass geogrid in the post-treatment process is designed for asphalt mixture, and each fiber is fully coated, which has high compatibility with asphalt, ensuring that fiberglass geogrid will not be isolated from asphalt mixture in the asphalt layer, but firmly bonded together.

　　After being coated with a special post-treatment agent, the fiberglass geogrid can resist various physical and chemical erosion, as well as biological erosion and climate change, ensuring its performance is not affected.
