| 1 | Pavement milling (cold planning, asphalt milling, or profiling) of existing all kinds of bituminous surfaces (Mastic, DBM, BC, SDBC, SMA, PMC etc.) with specially designed equipment up to the specified depth of bituminous layer as per designed level & grade, including disposal of milling material with all lead (minimum 20 km from site) and lift complete as per specification. The surface shall be free of bumps, ruts, and other imperfections including the arrangement of traffic diversion if required. Milling material recovered, shall be loaded directly onto trucks/trolleys from the milling machine & shall be the property of the contractor. The milled road surface shall be swept clean prior to opening to traffic. The milling machine is power-operated, self-propelled, and self-sufficient in power, traction, and stability to remove a thickness of BT surface to a specified depth. The machine should be able to provide a uniform profile and cross slope, and capable of accurately and automatically establishing profile grades along each edge of the machine by referencing from the existing pavement without damaging the bottom CC surface if any. The machine should have an automatic system for controlling grade elevation and cross slope etc. |

Bitumen (VG-30) Grading - II (26.50 mm (Nominal Size)) |
| 9 | Providing and laying bituminous concrete with 100-120 TPH batch type hot mix plant producing an average output of 75 tonnes per hour using crushed aggregates of specified grading, premixed with bituminous binder minimum @ 5.2 & 5.4 per cent of mix and filler, transporting the hot mix to work site, laying with a hydrostatic paver finisher with sensor control to the required grade, level and alignment, rolling with smooth wheeled, vibratory and tandem rollers to achieve the desired compaction as per MoRTH Specifications Clause 507 complete in all respects. for Grading-II(13 mm nominal size) Bitumen (VG-30) |
| 10 | Labour charges for placing and compacting kandhal readymade cold bituminous patching mix in potholes in adverse weather including cleaning of potholes, placing and compacting the mix, sprinkling sand to prevent pick up by traffic and documentation of patches, with all leads and lift complete in all respects as per direction of engineer-in-charge |
| 11 | Repair of pot holes / patch on road by 2.0 X 1.0 Square meter Infrared heater in seamless and regular shape through Infrared Recycling Pothole and road repair mobile Machine through heating the adjoining road surface up to the required temperature with flame less device to scrap exiting top road surface to the required thickness to retrieve the bituminous mix to actual even surface. The machine is containerized in single vehicle proceed in which all the three M’s i.e. Manpower, Machine and Material are available on the single vehicle itself, Recycling the material so retrieved, rejuvenated the bituminous loss with rapid setting emulsion -1 @ 3.25 liters.
