RCC M25 in Pavement — Supplying <(>&<)> laying reinforcement cement concrete of grade M25 (design mix) with 20mm down aggregate and OPC/ PPC cement of approved make with minimum cement content of 475 kg/m3, in thickness as mentioned in the drawing in long panels with necessary slope using screed vibrators, etc., in RCC pavement, drain and any other works as directed including tamping, flooded curing using temporary bunds for 14 days, finishing the surface and roughening of top surface using brooms as anti-skid measures. The rates shall include the cost of necessary steel Channel shuttering for RCC pavement (but excluding the cost of steel reinforcement) to maintain the line and level of the pavement/ drain to achieve a flat and smooth surface within the specified tolerance, cleaning and preparing the base surface and other necessary bye-works etc., all complete as per specification, drawings and direction of the engineer. The scope includes supply <(>&<)> placement of locally available ordinary polyethylene sheet before placement of concrete. The thickness of RCC pavement shall be 200mm in general. The thickness of concrete at edges, RCC drains or at other places shall be different and the same shall be duly indicated in the drawing. The scope of job also includes vacuum dewatering and roughening of top surface for friction Purpose

Expansion joint in pavement: — Supplying <(>&<)> laying expansion joint 20 mm thick with approved bitumen impregnated fibre board in between pavement edges <(>&<)> sealing the top 20 mm depth with poly-sulphide sealant at all heights <(>&<)> location with all bye works complete as per drawing, standard practice and as directed by the engineer.

Construction joint in pavement — Providing contraction joint by making grooves of 10 mm wide <(>&<)> 20 mm deep by saw-cutting on Rigid RCC pavements etc and filling the grooves with approved mastic sealant including all bye works and supply of all materials and tools complete as per drawing and as directed by engineer

Boulder Soling — Providing and laying stone boulder soling with stone boulders of size 150 mm including packing filling interstices with smaller size stones dry and wet consolidition with moorum as coarse aggregate in RCC pavement, foundation, trenches, including ramming, consolidating with 10T road roller in pavement and by mechanical means and tamping in foundation etc. completed as directed at the site (Compacted thickness shall be measured for payment)

Paver Block — Supply and laying of 80 mm thick glazed interlocking paver blocks of M40 grade over river sand bed of compacted thickness 50 mm and approved colors in approved design, brand and pattern as directed, of compressive strength 400 Kg/ sq. cm. placing each against its neighbour on the un-compacted sand, cutting the pieces to fill up edges next to the edge restrains. The paver blocks should have chamfered top edges of not less than 4mm and shall be laid with a min. of 2 mm gap which in turn shall be packed with sand and compacted with plate/ surface vibrator to the correct line, level and gradient and as directed by EIC. After lying compact with vibrator. Sweep dry fine sand over the surface, making sure it fills all the gaps between the paver. Vibrate the area again to give strong interlocking bond. Sweep off excess sand including all work complete as per direction of engineer-in-charge. Interlocking blocks pattern to be approved by EIC
