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)

Full Depth Reclammation process of existing Flexible Pavement in 5.8 m width and 250mm depth. 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 chemical additives / otherwise: Providing Iverizing, spreading, milling and mixing of chemical additives at the appropriate rate as per job mix design in accordance with IRC-72-2015 and IRC-37-2012. Cementitious additive @ rate of minimum 4% 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 and complete
