What is GSB?
GSB (Granular Sub Base) forms the bottom-most layer of a road pavement. It distributes load, improves drainage, and prevents capillary rise to protect upper layers.
- Crushed stone & river-bed aggregates
- Supports WMM layer above
- Enhances load transfer & drainage
What is WMM?
WMM (Wet Mix Macadam) is a mechanically mixed, well-graded aggregate layer placed above GSB, ensuring strong stability and superior compaction.
- Well-graded aggregates + water
- Laid using mechanical paver
- Compacted with vibratory rollers
