The work shall be executed using a cold milling machine such as Wirtgen W100H or equivalent, having a minimum milling width of 1 meter and a capacity of at least 100 HP, capable of achieving the desired depth in a single pass. The milled surface shall be uniform, free from loose material, and prepared for subsequent works. Milled material shall be collected and loaded into suitable transport vehicles immediately to prevent site obstruction. The quoted rate shall include all costs necessary to complete the work but not limited to the cost of equipment mobilization, milling, collection, loading, fuel, tools, labor, and traffic safety arrangements. Approval of the Engineer-in-Charge for the machine and methodology is mandatory.

The Bituminous Concrete (BC)- work involves the supply and laying of VG-40 bitumen mixed with aggregates to restore the road surface in areas requiring patchwork or pothole filling. The BC mix shall be prepared in an approved Hot Mix Plant (HMP), ensuring that the bitumen and aggregates are mixed in the correct proportions. The prepared BC will be transported to the site and laid using a manual paver or small vibratory rollers. The laid material will be compacted to the specified thickness and density using vibratory rollers or hand rollers. The bitumen consumption for BC is expected to be 5.5 to 6.0 kg per sqm for a 25 mm compacted thickness. The quoted rate shall include all costs necessary to complete the work, but not limited to the cost of VG-40 bitumen, aggregates, transportation from the HMP, laying, compaction equipment, labor for laying and compaction, and ensuring quality control. The contractor shall ensure that the work is completed in compliance with MoRTH Section 507 specifications for BC, including the required material properties, compaction, and surface finish.
