Construction of Pavement with Interlocking paver blocks in Ukhrul District HQ roads.

Providing laying and compacting Granular Base/Sub base with naturally occuring Sand Gravel Material free from organic or other deleterious constituents spreading with Motor Grader and compacted by rolling with power roller of 8-10 capacity in layers not exceeding 150mm (spread thickness)

Cable duct across the road (provding and laying of a rcc pipe duct, 300 mm dia across the road (new constructon), extending from drain to drain in cuts and toe of slope to toe of slope in fills, constructing head walls at both ends, providing a minimum fill of granular material over top and sides of RCC pipe as per IRC:98-1997, bedded on a 0.3 m thick layer of granular material free of rock pieces, outer to outer distance of pipe at least half dia of pipe subject to minimum 450 mm iin case of double and triple row ducts, joints to be made leak proof, invert level of duct to be above higher tha ground level to prevent entry of water and dirt, all as per IRC: 98- 1997 and approved drawings.)
