Granullar Sub Base
 

After the Earth Work the Sub-Base of the road is constructed with Granular material. Granular sub-base (GSB) is constructed with well graded Granular Soil, maintaining suitable moisture content and compacted in layers not exceeding 100mm. Compaction is done till required density is achieved as per the design. A well finished GSB will be free from movement (under compaction equipment), ridges, cracks or loose material.
