Warp-Knitting Biaxial Uniaxial Polyester Reinforced Geogrid for Reinforcing Pavement Concrete Road
| Comparison Items | Polyester Geogrid | Fiberglass Geogrid |
| Raw Materials | High-strength polyester filament (PET) | Glass Fiber (E-glass) |
| Production Process | Warp knitting/braiding → Heat setting → Coating (PVC, SBR, etc.) | Warp Knitting/Knitting → Coating (Asphalt or PVC) |
| Tensile Strength Range | 20–800 kN/m, wide strength range | 30–200 kN/m, commonly used for low to medium strength applications |
| Elongation | Low (approximately 8–12%), with some ductility | Very low (approximately 2–5%), almost no elongation |
| Aging Resistance | Excellent resistance to acids, alkalis, corrosion, and durability | Relatively poor, sensitive to alkaline environments, prone to aging |
| Temperature Adaptability | -40°C to +60°C | -100°C to +200°C (higher heat resistance than polyester) |
| Weight | Lightweight, easy to transport and lay | Also lightweight, but the fiber is more brittle |
| Price | Slightly higher (depending on raw materials and process) | Relatively inexpensive |
| Main Applications | - Highway and railway subgrade reinforcement | - Asphalt pavement reinforcement |
| Service life | Long life (10–20 years or more, depending on working conditions) | Medium (5–10 years, requires good maintenance) |
| Adhesion | Good adhesion between the coating and the soil/asphalt | Excellent adhesion to asphalt (commonly used in asphalt pavement) |
✅ Brief Summary:
Polyester geogrid → Suitable for geotechnical engineering and long-term load-bearing reinforcement (roadbeds, slopes, and embankments).
Fiberglass geogrid → More suitable for pavement maintenance and crack prevention (especially asphalt pavement reinforcement).
