Glass fiber geogrid is a high-performance reinforcement material made from glass fibers woven into a mesh structure. This unique design not only protects the glass fibers but also enhances the overall mechanical performance of the product. After undergoing a special coating process, it becomes a composite geosynthetic material that offers exceptional durability and compatibility with asphalt mixtures.
The primary component of glass fiber is silicon dioxide, an inorganic compound known for its remarkable physical and chemical stability. It exhibits high tensile strength, excellent stiffness, strong wear resistance, and outstanding cold resistance. Additionally, it does not suffer from long-term creep, ensuring consistent performance over time. Its thermal stability allows it to withstand high temperatures during paving operations, making it ideal for use in road construction.
The mesh structure of the geogrid enables mechanical interlocking with aggregates in the asphalt mixture, which significantly improves load distribution and prevents deformation under heavy traffic. The surface is coated with a modified asphalt layer, enhancing adhesion between the geogrid and the pavement. This dual-layer system boosts the geogrid's resistance to wear and shear forces, making it a highly effective reinforcement solution.
In some applications, the geogrid can be combined with self-adhesive pressure-sensitive materials and asphalt impregnation, allowing it to bond tightly with the pavement. This integration increases the friction coefficient between the grid and the surrounding soil, improving the pull-out resistance of the embedded geogrid. As a result, it provides superior reinforcement for roads, embankments, and other civil engineering structures.
The geogrid is also lightweight and flexible, making it easy to cut, connect, and install on-site. It can be overlapped or layered without the need for specialized equipment or skilled labor, further simplifying the construction process.
Key Features of Glass Fiber Geogrid:
1. **High Tensile Strength & Low Elongation** – With a break elongation of less than 3%, it resists deformation effectively.
2. **No Long-Term Creep** – Ensures long-lasting performance under continuous loading conditions.
3. **Thermal Stability** – Resists melting at temperatures above 1000°C, suitable for hot paving processes.
4. **Asphalt Compatibility** – Fully coated fibers ensure strong bonding with asphalt mixtures.
5. **Physicochemical Stability** – Resists wear, corrosion, biological erosion, and weathering.
6. **Aggregate Interlocking** – Enhances compaction and load transfer, reducing deformation and improving pavement life.
