Hubei steel-plastic geogrids significantly enhance the composite performance with asphalt pavements.
Release date:
2020-11-09
Hubei Huanggang Foshan steel-plastic geogrids boast high strength, high modulus, excellent chemical stability, superb corrosion resistance, low thermal expansion coefficient, and outstanding dimensional stability. After surface modification and coating treatment, the material’s surface properties are significantly enhanced, boosting its compatibility with asphalt and dramatically improving the substrate’s wear resistance as well as shear strength. When used in asphalt overlay applications, Hubei Huanggang Foshan steel-plastic geogrids can play a critically important role in several key areas.
I. Mitigating Reflective Cracking: Reflective cracking occurs when significant displacement near existing concrete pavement joints or cracks induces stress concentrations within the overlying asphalt overlay. This phenomenon encompasses both horizontal movements caused by temperature and moisture fluctuations, as well as vertical shear displacements resulting from traffic loads. The former leads to highly concentrated tensile stresses in the asphalt layer directly above the joints or cracks, while the latter subjects the asphalt overlay above the joints to substantial flexural-tensile and shear stresses.
Thanks to the reinforcing effect of Gao Intensity Hubei Huanggang Foshan steel-plastic geogrids on the asphalt overlay layer, it is possible to reduce the thickness of the asphalt overlay while effectively controlling reflective cracking, thereby lowering construction costs and achieving significant economic benefits.
2. Crack Resistance: In asphalt overlay layers, the Foshan steel-plastic geogrid from Huanggang, Hubei, effectively disperses compressive and tensile stresses, creating a buffer zone between two stress-concentrated areas. This allows stress to transition gradually rather than change abruptly, significantly reducing the risk of damage to the asphalt overlay caused by stress discontinuities. Additionally, its low elongation rate minimizes pavement deflection, ensuring that the road surface remains free from excessive deformation.
III. High-Temperature Rutting: Asphalt concrete exhibits rheological behavior at elevated temperatures, specifically manifesting as softening and stickiness of the asphalt pavement surface during summer months. Under vehicle loads, the stressed areas develop depressions, and after the loads are removed, the asphalt surface fails to fully return to its original condition—resulting in permanent plastic deformation. Over time, repeated vehicle traffic compacts this plastic deformation further, ultimately leading to the formation of wheel ruts.
