Once the Sub-Base is prepared, the base course is required to provide the strength to the road. Generally, the base course is constructed with the help of stone metal and other suitable materials.

Water Bound Macadam (WBM) base course is constructed with graded aggregate in two or three layers as per the design. Each layer, with appropriate graded aggregate, is spread to proper profile and dry rolled. Screenings (small size aggregate) are applied over the rolled aggregate and water is sprinkled.

Thereafter, binding material (soil with PI < 6) is applied and sprinkling of water is repeated. The resulting slurry is swept in with brooms so as to fill the voids properly and rolled again. After final compaction, the road is allowed to cure overnight before opening to traffic.
