Construction of Granular sub-base by providing well graded material, spreading in uniform layers with motor grader on prepared surface, mixing by mix in place method with rotavator at OMC, and compacting with smooth wheel roller to achieve the desired density, complete as per Technical Specification Clause 401.as per Data Book item No. 4.1(A)-(i) confirming to grading of GSB table 400.1 ( grade-1) by mix in place method

FDR 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 fited 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 equipments 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)
