Reinforcing Glass Grid Asphalt Fiberglass Geogrid 120Kn Preventing Road Surface Cracks
1. Fiberglass geogrid Basic definition and structure
Material composition
Based on alkaline glass fiber yarn, it is coated with modified asphalt or polymer material to form a grid structure.
It has high strength, low elongation (<4%), high temperature resistance (melting point 1000℃) and low temperature resistance (-100℃).
Structural features
The warp knitting process enhances the fiber strength, improves the tensile, tear and creep resistance.
The coating process can enhance the wear resistance and shear resistance and extend the service life.
2. Mainly application place
Road engineering
Asphalt pavement reinforcement: prevent reflective cracks and delay rutting, suitable for old cement road reconstruction, bridge and tunnel connections, etc.
Roadbed reinforcement: control uneven settlement at the junction of new and old roadbeds.
Slope protection, dam reinforcement, reservoir anti-seepage and other scenarios, provide anti-scouring and soil stability.
3. Advantages and performance
Mechanical properties
High tensile strength (elastic modulus is 20 times higher than asphalt concrete), low elongation (<3%), no long-term creep.
Corrosion and chemical erosion resistance (good compatibility with asphalt mixture).
Convenience of construction
Closely combined with asphalt pavement, high construction efficiency, and lower cost than traditional steel materials.
4. Technical standards
Yixing Shenzhou Fiberglass Geogrid has passed CE certification and complies with ISO quality system requirements.
5. Construction technology reference
Construction needs to be combined with slope leveling, material laying and compaction technology, please refer to technical documents.
Application cases include highway, railway roadbed reinforcement and ecological slope protection projects
