Flexible pavement construction is a widely used method for building roads, highways, and other transportation infrastructure. It offers several advantages, including cost-effectiveness, durability, and ease of maintenance. One crucial component of flexible pavement construction is the use of geogrids, which provide reinforcement and stability to the pavement structure. Among the various types of geogrids available, PVC coated polyester geogrids have gained popularity due to their excellent performance and ease of installation.
When it comes to installing PVC coated polyester geogrids, there are certain techniques and best practices that need to be followed to ensure optimal results. The first step in the installation process is to prepare the subgrade. The subgrade should be properly compacted and free from any debris or loose materials.
