Construction of Subgrade and Earthen Shoulder with approved soil with all lifts and leads 1000 mts, laying in layers, breaking clods, dressing to required lines, curves, grade and sections, watering and compaction to meet at least 100 % procter density complete to specification requirements

Dismantling of flexible pavements and disposal of dismantled materials upto a lead of 100 m, stacking serviceable and unserviceable materials separately as per Technical Specification Clause 202, By Manual Means (Granular Courses)

Stabilization 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 mix design in accordance with IRC-SP-72-2015 , IRC-37-2012 & 2018 and IRC SP 89 (part II) 2018. Cementitious additive @ rate of minimum 5 - 7% and CCS/CS additive should be spread on the existing pavement using a mobile truck mounted containerized cement/ additive spreader with micro processor 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 horse power of 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 in-situ process would be carried out in single pass with milling and pulverising of damaged asphalt pavement / soil/ aggregates / soil-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 be followed by Pneumatic Tyre Roller. The minimum unconfined compressive strength (UCS) of stabilized sub base/ 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 sub base 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's 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).

Providing and applying primer coat with bitumen emulsion (SS-1) on prepared surface of granular base including cleaning of road surface and spraying primer at the rate of 0.85 kg/sqm using mechanical means as per Technical Specification Clause 502
