Glass fiber geogrid is a high-performance geosynthetic material that combines the strength of glass fibers with advanced coating technologies. It is manufactured through a specialized weaving process, and then coated with a unique layer to enhance its durability and compatibility with asphalt mixtures. The primary component of the glass fiber is silicon dioxide, an inorganic compound known for its stability, strength, and resistance to environmental degradation. This makes the geogrid highly resistant to wear, temperature fluctuations, and long-term deformation. Its mesh structure allows it to interlock with aggregates, providing enhanced load distribution and improving the structural integrity of asphalt pavements. In addition to its mechanical properties, the geogrid is often treated with modified asphalt or pressure-sensitive adhesives, which help it bond more effectively with the surrounding pavement materials. This integration ensures that the geogrid remains firmly embedded within the asphalt layer, increasing the friction between the grid and the soil or aggregate. As a result, the pull-out resistance is significantly improved, making it ideal for reinforcing weak or unstable subgrades. The lightweight and flexible nature of the geogrid also makes it easy to handle on-site—cutting, connecting, and overlapping can be done without the need for specialized tools or skilled labor, further simplifying the installation process. Glass fiber geogrid offers several key advantages: 1) High tensile strength and low elongation – The geogrid is made from high-strength glass fibers, which provide excellent resistance to deformation. Its elongation at break is typically less than 3%, ensuring minimal stretching under load. 2) No long-term creep – Unlike some traditional reinforcement materials, glass fiber does not exhibit creep over time. This means it maintains its shape and performance even under prolonged stress, making it a reliable choice for long-term infrastructure projects. 3) Thermal stability – With a melting point exceeding 1000°C, the geogrid can withstand the high temperatures encountered during asphalt paving operations without losing its structural integrity. 4) Compatibility with asphalt – The surface treatment applied to the geogrid is specifically designed to work with asphalt mixtures. Each fiber is fully coated, ensuring strong adhesion and preventing separation within the asphalt layer. 5) Physicochemical stability – After undergoing special coating processes, the geogrid becomes resistant to chemical corrosion, biological erosion, and weathering, maintaining its performance over time even in harsh environments. 6) Aggregate interlocking and restriction – The open mesh design allows aggregates to pass through, creating a mechanical lock that prevents their movement under traffic loads. This improves compaction, increases load capacity, and reduces pavement deformation, leading to longer-lasting road surfaces.
