WBM surfacing of temporary CT road at Lajkura OCP mine under IB Valley Area

Construction of granular sub-base by providing well graded material like natural sand crushed gravel or crushed stone having CBR >30, spreading in uniform layers withmotor grader on prepared surface, mixing by mix in place method at OMC withrotavator and compacting with vibratory rollers of 80 to 100 kN static weight to achievethe desired density, complete as per Clause 401 of Specification for grading-III Material.

Water Bound MacadamProviding, laying, spreading and compacting stone aggregates of specific sizes to waterbound macadam specification including spreading in uniform thickness, hand packing, rollingwith vibratory roller 8-10 tonnes in stages to proper grade and camber, applying and brooming requisite type of screening/ binding Materials to fill up the interstices of coarse aggregate,watering and compacting to the required density as per clause 404 of specification By Mechanical Means:Grading- I (63 to 45 mm) Using Screening Type-A (13.2mm Agg.)
