Dismentling of Structures Dismentling of Existing Brick Edging complete in all respect. as per

Credit of Bricks (3rd Class) received after dismentling

Credit of Brick bats

Dismantling of flexible & granular pavements and disposal of dismantled materails upto a lead of 100 m stacking serviceable and unserviceable materials separately as per Technical Specification Clause 202.

Laying & Compaction of Dismantled Material received after scarification from raising/Reconstruction portion including Laying , spreading in uniform layers with motor grader and light compation with smooth wheel roller as per technical Specification clause 401.

Construction of embankment with approved material obtained from borrow pits with a lift upto 1.5 m transporting to site, spreading, grading to required slope and compacting to meet requirement of Tables 300.1 and 300.2 as per Technical Specification Clause 301.5

Providing laying, spreading and compacting stone aggregates of specific sizes to water bound macadam specification including spreading in uniform thickness, hand packing, rolling with smooth wheel roller 80-100 kN in stages to proper grade and camber, applying and brooming, stone screening(Type A)/binding materials to fill up the interstices of coarse aggregate, watering and compacting to the required density grading 2 ( 63-45 mm ) as per Technical specification Clause 405.

Providing laying, spreading and compacting stone aggregates of specific sizes to water bound macadam specification including spreading in uniform thickness, hand packing, rolling with smooth wheel roller 80-100 kN in stages to proper grade and camber, applying and brooming, stone screening(Type B)/binding materials to fill up the interstices of coarse aggregate, watering and compacting to the required density grading 3 ( 53 - 22.4 mm ) as per Technical specification Clause 405. raising portion (grade improvement portion)

Stabilisation of in-situ (existing pavement crust) or soil or otherwise sub base/base course up to the required depth by cold in-situ recycling using cement and chemical additives/otherwise: Providing pulverizing, spreading, milling and mixing of chemical additives at the appropriate rate as per job in mix design in accordance with IRC-SP-72 2015, I RC-37-2012 & 2018 and IRC SP 89 (part-II) 2018. Cementitious additive @ rate of a minimum ofas per dnit and CCS/CS additive should be spread on the existing pavement using a mobile truck mounted containerized cement/additive spreader with microprocessor controlled weighing and spreading system. The additive spreader shall have variable working width sufficient to cover whole pavement lane. The in-situ stabilization process shall be carried out by a mobile and self-propelled stabilizer/reclaimer of working width of 2.4 m and with minimum engine horsepower 440 kw with a variable working depth up to 50 cm. The resultant stabilized mix then would be profiled to the required grade, level and thickness using motor grader and the mix would be compacted using 20 tonne pad foot roller in combination with smooth wheel roller to achieve desired proctor density as per IRC 37-2012 & 2018 and complete in all respect and curing with water as required including all materials, labour and machinery etc. The entire insitu process would be carried out in single pass with milling and pulverising of damaged asphalt pavement/soil/ aggregates/soi1-aggregate mixture to the desired depth and with simultaneous addition of additives and water with machine integrated spray bars fitted on the wheeled self-propelled and vibratory pad foot roller to achieve the desired proctor density in all respects. The tandem roller should be followed by Pneumatic Tyre Roller. The minimum unconfined compressive strength (UC’S) of’ stabilized subbase/base should be 4.5 to 7 MPa after 7/28 days of curing as per IRC-SP-72-2015, IRC-37-2012 & 2018 Also durability aspects (wet-dry cycles) of stabilized subbase should be satisfied as per IRC 37-2012 & 2018 and IRC SP 89 (part II) 2018. The gradation mixes and materials should be as per IRC 37-2012 & 2018 and IRC SP 89 (part II) 2018. The train of equipment to be used are binder spreader- water Tanker - Additive Truck - Recycler - Padfoot Roller (20 Tonne) + Single Drum Compactor- Grader- Tandom Roller- Pneumatic Tyre Roller (20 Tonne).
