Fiberglass Geogrid with High Tensile Strength Warp Knitted
As a professional manufacturer of warp knitted fiberglass geogrid, we specialize in high tensile strength solutions for asphalt reinforcement. Our factory ensures strict quality control, stable production capacity, and reliable performance for global infrastructure projects.
What Is High Tensile Fiberglass Geogrid?
High tensile fiberglass geogrid is manufactured from high-strength glass fiber yarns with a durable polymer or bitumen coating. It is specifically engineered for asphalt reinforcement applications where high tensile modulus and low elongation are critical. Installed between asphalt layers, it acts as a stress-absorbing interlayer that prevents crack propagation and improves structural performance.
Why High Tensile Strength Matters in Road Construction
Road pavements are constantly subjected to tensile stress caused by traffic loads and temperature changes. Without reinforcement, these stresses lead to cracking, rutting, and premature failure. A high tensile fiberglass geogrid provides strong resistance to deformation, redistributes loads efficiently, and significantly reduces maintenance cycles.
Engineering Problems We Solve
Reflective Cracking
Acts as a barrier layer to absorb tensile stress and prevent cracks from reaching the surface.
Rutting & Deformation
Improves load distribution, reducing permanent deformation under repeated traffic loading.
Short Pavement Life
Extends service life by strengthening asphalt layers and minimizing structural fatigue.
Key Advantages
High Tensile Strength
Up to 200 kN/m, ideal for heavy-duty traffic conditions.
Low Elongation
Less than 4%, ensuring immediate reinforcement effect.
Thermal Stability
Performs reliably under asphalt paving temperatures.
Chemical Resistance
Resistant to corrosion, UV exposure, and environmental degradation.
Applications
It is widely used in asphalt pavement reinforcement, effectively controlling reflective cracking and extending road service life. It is ideal for highways, municipal roads, airport runways, and bridge decks. Additionally, it is applied in old pavement overlays, parking areas, and heavy-load industrial roads, improving structural stability, load distribution, and resistance to deformation under repeated traffic stress.
How to Choose the Right Geogrid?
Selecting the correct fiberglass geogrid depends on project requirements such as traffic load, pavement thickness, and environmental conditions. For heavy traffic highways, high tensile strength (≥100 kN/m) is recommended. For municipal roads, medium-strength options may be sufficient. Coating type should also be selected based on asphalt compatibility and climate conditions.
Installation Guidelines
- Ensure surface is clean and dry before installation
- Apply tack coat evenly before laying geogrid
- Roll out geogrid without wrinkles or folds
- Ensure proper overlap between adjacent rolls
- Compact asphalt layer immediately after placement
