GSB

GSB is a layer of compacted granular material, typically crushed stone or gravel, used as a base course beneath pavements, roads, and runways.

Properties:

1. Granular texture

2. High drainage capacity

3. Good load-bearing capacity

4. Resistance to settlement and deformation

5. Durability and stability

Applications:

1. Road construction (sub-base, base course)

2. Airport runway construction

3. Pavement construction (parking lots, sidewalks)

4. Railway track construction

5. Building foundations (sub-structure)
