GSB (Granular Sub Base)
Granular Sub Base (GSB) is a crushed stone layer used as a foundation for roads, highways, and pavements. It acts as a supportive base between the natural ground and upper pavement layers, ensuring stability, load distribution, and drainage. GSB plays a crucial role in road construction by reducing settlement, improving compaction, and enhancing pavement life.
Benefits
- Strengthens Road Foundations – Provides a firm and stable base for highways and pavements, preventing surface failures.
- Effective Load Distribution – Minimizes stress on upper layers by evenly distributing traffic loads.
- Enhances Drainage – Allows water to pass through, preventing waterlogging and improving road durability.
- Prevents Soil Erosion – Protects underlying soil from displacement, ensuring long-term road stability.
- Cost-Effective & Sustainable – Reduces the need for frequent maintenance and improves pavement lifespan.
Applications
Highways & Roads – Used as a sub-base layer to provide strength and durability.
Airport Runways – Enhances load-bearing capacity for high-traffic areas.
Railway Tracks – Supports tracks by preventing ground shifts and maintaining alignment.
Industrial & Commercial Areas – Used in parking lots, warehouses, and factory flooring for a solid foundation.
