Dismantling of existing Black top Surface (flexible Pavement) to a depth of 50 millimetre manually including loading of dismantled material to transport vehicle at site excluding lead charges

Excavation for roadway in earth, soil of all sorts, sand, gravel or soft murum including dressing section to the required grade, camber and side slopes and conveying the excavated materials with all lifts upto a lead of 50 metre. and spreading for embankment or stacking as directed.

Conveying and disposing of excavated road material at distance of 2 kilometre from road site.

Supplying hard murum/ kankar at the road site, including conveying and stacking complete.

Spreading hard murum/ soft murrum/ gravel or kankar for side width complete

Compacting the hard murum side widths including laying in layers on each side with vibratory roller including artificial watering excetra complete.

Construction of granular sub-base by providing close graded material, spreading in uniform layers with motor grader/ Paver on prepared surface, mixing by mix in place method with rotavator at OMC, and compacting with vibratory roller to achieve the desired density, complete as per clause 401 -- By Mix in Place Method and Grading - III Material

Providing, laying, spreading and compacting stone aggregates of specific sizes to water bound macadam specification including spreading in uniform thickness, hand packing 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 with Vibratory roller. to the required density. By Mechanical Means - Grading I (Using Screening Type A (13.2) millimetre Aggregate)

Stabilization of Soil or Sub-Base/Base Course or Existing Pavement Crust upto the required depth by In-Situ Stabilization method using Cement / Cementitious additives / Chemical additives / Combination: Providing and pre-spreading of Binder (Cement / Cementitious additives / Chemical additives / combination) at rate of required quantity (% by weight) as per job mix design in accordance with IRC 37-2018 using a truck-mounted automated binder spreader with micro-processor controlled weighing and spreading system. The binder spreader shall have variable working width upto 2.4 metre to efficiently manage the width of the whole pavement. The in-situ stabilization process shall be carried out using a self-propelled wheeled Stabilizer / Reclaimer with a minimum working width of 2 metre or 2.4metre and minimum engine horsepower of 305 kW having in-built automated water-spraying and depth control systems with variable working depth of up to 500 millimetre The entire in-situ process shall be carried out in a single pass including pulverizing of soil/ aggregates/ combination or milling of existing asphalt pavement and simultaneous mixing with pre-spread binder (cement/additive) and water to the desired depth. The resultant stabilized mix shall be compacted using a vibratory padfoot compactor of 14-20 tonne weight as per design depth and then graded to the required profile, level and thickness using a motor grader. The graded surface shall be then compacted using a smooth vibratory roller to achieve the desired proctor density as per IRC 37-2018 and complete in all respects including curing with water as required including all materials, labor, machinery, excetra Necessary graded stone aggregates shall be added by pre-spreading with cement to achieve desired gradation and profile of the road. The minimum unconfined compresssive strength (UCS) of stabilized sub-base should be 4.5 / 7 MPa after 7 / 28 days curing as per IRC 37-2018 .Also, durability aspects (wet-dry cycles) of stabilized sub base should be satisfied as per IRC 37-2018 .The gradation mixes and materials should be as per IRC 37-2018.

Construction of dry lean cement concrete Sub- base over a prepared sub-grade with coarse and fine aggregate ( natural sand/ VSI grade finely washed crushed sand) conforming to IS: 383, the size of coarse aggregate not exceeding 25 millimetre , cement content not to be less than 150 killograme per cubic metre, optimum moisture content to be determined during trial length construction, concrete strength not to be less than 10 Mpa at 7 days, mixed in a batching plant/ Weigh batch mixer, transported to site with all leads and lifts, laid with a paver with electronic sensor /by suitable means as approved by Engineer-in-charge , compacting with vibratory roller, finishing, curing and including preparation of sub-grade surface if required etc. complete. with fully automatic micro processor based PLC with SCADA enabled reversible Drum Type mixer/ concrete Batch mix plant (Pan mixer) excetra complete.
