This paper will introduce the application of Geogrid in highway engineering and discuss its important role as an important geosynthetic material in highway construction.
Geogrid is a geosynthetic material made of polymer or glass fiber, etc., with excellent tensile strength and stiffness. In highway engineering, Geogrid is widely used in subgrade reinforcement and pavement reinforcement to improve the carrying capacity of the highway and reduce the subsidence deformation.
Taking the reconstruction and expansion project of a highway as an example, because the foundation soil is relatively soft, the Geogrid is used to strengthen the subgrade in the design scheme. In the process of engineering construction, a certain thickness of Geogrid is laid under the subgrade, and then filled and tamped to form a solid subgrade structure. This design can effectively increase the bearing capacity of the roadbed, prolong the service life of the highway, and reduce the maintenance cost.
In addition to the application of subgrade reinforcement, Geogrid can also be used for pavement reinforcement to improve the crack resistance and durability of the pavement. By laying the Geogrid grid under the asphalt concrete layer, the cracks and deformation of the pavement can be effectively reduced, and the stability and flatness of the pavement can be improved.
In summary, Geogrid, as a geosynthetic material, plays an important role in highway engineering. Its application can not only improve the overall quality and performance of the highway, but also reduce maintenance costs and promote the sustainable development of highway engineering.
