Polyester continuous filament needle-punched nonwoven geotextiles are widely used in the construction of motorways due to their excellent performance in separation and filtration. Here’s an overview of their application and advantages:
Applications in Motorway Construction
- Separation:
- Prevents mixing of different soil layers, such as subgrade soil and base course materials.
- Maintains the integrity of structural layers, ensuring long-term performance.
- Filtration:
- Allows water to pass through while retaining soil particles.
- Helps in controlling water drainage and reduces water pressure build-up in the subgrade.
- Reinforcement (Secondary Role):
- Distributes loads and minimizes rutting by improving the structural stability of the base layers.
Features of Polyester Continuous Filament Nonwoven Geotextile
- High Strength and Durability: The continuous filament structure ensures high tensile strength and resistance to tearing.
- Excellent Water Permeability: Needle-punched construction enhances permeability for effective drainage.
- Chemical and Biological Resistance: Resists degradation from acids, alkalis, and microorganisms commonly found in soil environments.
- Thermal Stability: Polyester material has a high melting point, making it suitable for construction in hot climates.
- Ease of Installation: Lightweight and flexible, enabling quick and cost-effective installation.
Benefits in Motorway Projects
- Reduces maintenance costs by stabilizing the road structure.
- Extends the lifespan of the motorway by improving load distribution and drainage.
- Prevents subgrade erosion and deformation under heavy traffic loads.
