Polyester Geogrid Solves The Problem Of Road Cracks In Mountainous Areas

The appearance of the polyester geogrid is a high-density mesh square hole structure. The longitudinal and transverse ribs can provide strong tensile properties and at the same time have sufficient elasticity to be used as a stone packing material without being torn or broken. Using polyester geogrids to reinforce the roadbed of mountain roads can effectively improve the durability and rigidity of the roadbed, and reduce fatigue cracks on the road surface. Because mountain roads are more susceptible to damage, especially the large temperature difference between day and night in this area, it is easy to cause high temperature expansion, cold shrinkage and cracking, especially the damage of plant roots, which leads to uneven roads.

The reason why polyester geogrid has stable crack resistance is mainly due to the stable physical properties of its raw materials and the elongation characteristics of the composite roadbed. The resulting polyester fiber is a polyester synthetic fiber formed by polycondensation of organic dibasic acid and diol, called PET fiber, which is a polymer compound. The material can effectively resist the damage of the root system of the big tree to the roadbed and road surface, similar to the uneven phenomenon caused by the root system of the big tree on the sidewalk, and can greatly reduce the uneven phenomenon caused by the root system of the big tree. The root system of the big tree. The use of pavement fiber grating can quickly form a rigid network structure between the base layer and the road surface, thereby avoiding cracks, especially on mountain roads.

In fact, the overall performance of polyester geogrid occupies a great advantage in mountain road construction.
