The geological conditions of the areas where the highway passes are very different, requiring a large number of filling and digging sections to connect, and there are many bridgeheads jumping, and the problems of side displacement and extrusion of roadbed materials under load seriously affect the service life and safety of the highway. . The use of traditional methods cannot stop the destructive erosion of the soil layer under the protective slope by rainwater, resulting in increased maintenance costs. If GeoGro's geogrid is used for slope protection, with grass seeds with developed root systems, it can not only stabilize the soil and protect the slope, but also green and protect the ecological environment, which meets the requirements of the country to pay attention to environmental protection and build green channels.
