Geotextiles are a thin, durable fabric used in road construction to improve soil structure, protect it from damage, and reinforce it. Geotextiles are placed between different layers of materials in the road structure to prevent mixing and ensure proper drainage. This separation prevents the intermixing of subgrade and aggregate materials, maintaining each layer’s integrity and extending the road’s lifespan.
They are used in a variety of ways, including:
- Separation: Geotextiles can keep different soil layers apart, preventing them from mixing and deteriorating. This helps each layer perform its function and prevents soil contamination.
- Stabilization: Geotextiles can increase the stability and strength of the soil in a roadway.
- Drainage: Geotextiles can help with drainage.
- Filtration: Geotextiles can help with filtration.
- Reinforcement: Geotextiles can be used to reinforce weak soils.
Geotextiles have several advantages over traditional construction materials, including:
- They are less expensive than soils and aggregates.
- They are easier to install.
- They have a smaller environmental impact.
- Reduces Construction Time
- Improves Safety
- Increases Road Lifespan
