Granular Sub Base (GSB) Mix
GSB stands for Granular Sub Base, which is a layer of granular material placed on a subgrade to provide a stable foundation for pavement layers above it. The GSB mix typically consists of a blend of aggregates such as crushed stone, gravel, or sand, mixed with fines like silt or clay.
Benefits of GSB Mix
- 1Stability: GSB provides a stable base for roads, highways, and other pavement structures, reducing the risk of settlement or deformation.
- 2Load Distribution: It helps distribute the load from the pavement to the underlying soil, preventing excessive stress on the subgrade.
- 1Drainage: GSB allows for proper drainage of water, reducing the risk of water accumulation and potential damage to the pavement structure.
- 1Strength: The compacted GSB layer increases the overall strength of the pavement, enhancing its durability and longevity.
- 1Cost-Effectiveness: By providing a stable base, GSB can reduce the need for thick pavement layers, resulting in cost savings in construction and maintenance.
- 1Environmentally Friendly: GSB can be made from recycled materials, reducing the need for virgin aggregates and promoting sustainability in construction projects.
