| 1 | Scarifying gravelled macadam or bitumen macadam surface 6 cm to 10 cm.depth including stacking useful materials on road side and disposing off remaining stuff. | 301138.000 | Sqmt. |
| 2 | Soil Stabilisation-Stabilization of in-situ (existing pavement crust) or soil or otherwise sub-base course upto the required depth bycold in-situ recycling using chemical additives/otherwise : Providing pulverizing, spreading, milling and mixing of chemical additives at the rate of minimum 650 ml/cum required quantity as per job mix design in accordance with IRC37-2018.Cementitious additive at rate of minimum 4 Percentage 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 2.4mt and with minimum engine horse power of 440 kw with avariable working depth of minimum 50cm.There sultant stabilised 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 whell roller to achieve desired proctor density as per IRC37-2018 and complete in all respects and curing with water as required including all materials, labor and machinery etc. The entire In-situ process would be carried out in single pass with milling and pulverzing of damage dasphalt 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 desired proctor density in all respects. The minimum unconfined compresssive strength (UCS) of stabilized sub base should be 4.5 to 7 MPa after 28 days curing as per IRC37-2018. Also, durability aspects (wet-dry cycles) of stabilized sub base should be satisfied as per IRC37-2018. Including surface cement at 2 Kg/Sqm. to retard rutting before application of wearing coarse post monsoon as directed by engineer in charge. | 57068.000 | Cum. |
| 3 | Providing and laying a stress absorbing membrane interlayer (SAMI) / bitumen impregnated geotextile layer after cleaning the roadsurface,geotextile conforming to requirements of clause703.3, laid overa tack coat with1.05 kilogram per one square meter ofpaving grade bitumen 80-100 penetration/emulsion as per requirement and as directed by engineer incharge. | 67363.000 | Sqmt. |
| 4 | Providing and laying evenly priming coat with emulsion SS-1 at rate of 7.5 Kg/10 Sqm etc.complete | 435863.000 | Sqmt. |
| 5 | Providing & laying compacted 50 and 75 mm thick dense graded bituminous macadam (DBM) Grade-II in Single layer using 100-120 TPH Batch Mix Plant HMP producing an average output of 75 tonnes per hour, tack coat at the rate of 2.5 kg / 10 m2 in each using crushed aggregates of specified grading . premixed with bituminous content at 4.5 Percentage (VG-40) by weight of total mix and filler , transporting the hot mix to work site laying with a hydrostatic paver finisher with sensor control with minimum road width or as directed by Engineer in charge to the required grade, level and alignment, rolling with smooth wheeled vibratory and tandem rollers to acheive the desired compaction as per MORTH specification etc complete in all respects. The agency shall have to get the mix design done from approved laboratory and submit to the Engineer in charge for approval. If the asphalt (bituminous) content is more than above, the agency shall have to bear the cost of additional asphalt. The payment shall be done on the permissible field density achieved on the site instead of density derieved in the mix design.( Assume density 2.3gms/cm3) | 59692.000 | MT. |
