Geogrid is a major geosynthetic material, which has unique performance and efficacy compared to other geosynthetic materials. Commonly used as reinforcement for reinforced soil structures or composite materials. Geogrids are divided into four categories: plastic geogrids, steel plastic geogrids, glass fiber geogrids, and polyester warp knitted polyester geogrids. Grille is a two-dimensional grid or three-dimensional grid with a certain height formed by thermoplastic or molded high polymer materials such as polypropylene and polyvinyl chloride. When used in civil engineering, it is called a geogrid.
Due to poor stiffness and deformability, cement concrete pavement undergoes uneven local settlement, which changes the stress state and operating conditions, increases the internal stress of concrete blocks, leading to damaged concrete blocks and reducing the lifespan of the concrete pavement.
How to solve this problem and prevent road damage? The excellent characteristics of geogrids and special surface treatments have three effects. Firstly, laying geogrids enhances the overall strength of the base on the lime soil surface of the base layer. Then spray the layer of hydrothermal asphalt heavy oil (oil or binder layer), which can effectively prevent the erosion of rainwater lime soil on the surface of the base material layer, thus extending the life of lime soil base. Secondly, geogrids can effectively prevent cracking on cement pavement caused by low temperature shrinkage due to fatigue of the base ash and soil.
Geogrid reinforced concrete can serve as a reinforcing member for its reinforced concrete, and the road load stress can be evenly spread to prevent reflection cracks, thereby extending the service life of the concrete pavement.
