Anhui fiberglass grid distributor 80KN fiberglass geogrid manufacturer

Description :

　　The application of fiberglass geogrid in asphalt overlay layer greatly improves the tensile strength of asphalt concrete, which can resist large tensile stress without damage. In addition, even if the stress at the location of the crack is too concentrated due to the formation of cracks in a local area, it gradually disappears through the transmission of fiberglass geogrids, and the crack will no longer develop into a crack. When selecting fiberglass geogrid, in addition to meeting the performance indicators specified in the table above, special attention should be paid to ensuring that its width is not less than 1.5m to meet the requirement of having sufficient cross-sectional area to fully dissipate crack energy when used as a control reflection crack interlayer; At the same time, the mesh size should be 0.5-1.0 times the particle size of the asphalt surface material on top, which helps to achieve shear adhesion, promote aggregate interlocking and restriction. Fiberglass geogrid is mainly used for:

　　1. Old asphalt concrete pavement with reinforced asphalt surface layer to prevent and control diseases.

　　2. Reconstruction of cement concrete pavement into composite pavement to suppress reflection cracks caused by plate shrinkage.

　　3. Road expansion and renovation projects to prevent cracks caused by new old joints and uneven settlement.

　　4. Reinforcement treatment of soft soil foundation is beneficial for the consolidation of water in soft soil, effectively suppressing settlement, evenly distributing stress, and enhancing the overall strength of the roadbed.

　　5. Shrinkage cracks occur in the semi steel base layer of newly built roads, and reinforcement is added to prevent pavement cracks caused by the reflection of foundation cracks.
