Providing, laying, spreading and compacting graded stone aggregate to wet mix macadam specification including premixing the Material with water at OMC in mechanical mix plant, laying in uniform layers with paver in sub- base / base course on well prepared surface and compacting with vibratory roller to achieve the desired density complete as per technical clause 406 of MORT&H specifications

Providing and applying primer coat with bitumen emulsion SS on prepared surface of granular base including cleaning of road surface and spraying primer at the rate of 0.85kg/sqm complete as per technical clause 502 of MORT&H specifications

Providing and applying tack coat with bitumen Emulsion Grade RS using pressure distributor at the rate of 0.25 kg per sqm on the prepared bituminous surface/granular surface treated with prime coat after cleaning the surface complete as per technical clause 503 of MORT&H specifications

Providing and laying dense graded bituminous macadam 50mm to 75mm thick with batch type HMP using crushed aggregates of specified grading, premixed with bituminous binder VG-40 @ 4.5%, 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 complete as per technical clause 505 of MORT&H specifications NOTES (i) Job mix formula for the dense graded bituminous macadam shall be provided by the agency and shall be got approved from Punjab PWD B&R Research Laboratory Patiala before adoption at site for execution. (ii) The specification of this item for analytic purpose is kept with bitumen content @ 4.50% weight of mix variation as compared with job mix formula shall be paid/deducted accordingly. The limits of variation shall be worked out with the approved formula TECHNICAL NOTE:- 1.) Apart from the confirmity with the grading and quantity requirement of invidual ingredients exhibited above the mix aggregate i.e coarse and fine aggregate for dense graded bituminous macadam shall meet all requirements set forth clause 505 of MORT&H specifications. (ii) The final grading for the aggregates required for dense graded bituminous macadam confirming to table 500.10 of MORT&H specifications shall be determined after getting the dense graded bituminous macadam designed from Punjab PWD B&R Research Laboratory Patiala after obtaining 60% of material. The design mix so finally approved shall be termed as approved mix. The aggregate shall be hydrophobic and of low porosity. The aggregates shall satisfy the physical requirement set fourth in table 500-6(addendum to latest revision).iii) The approved mix shall exhibit the following details source and location of all material:- iii (a) Binder expressed as percentage by weight of total mix. iii(b) Course expressed as percentage by weight of total mix. iii (c) Crushed bajri expressed as percentage by weight of total mix. iii(e) A single definite percentage passing each sieve for mixed aggregates.iii(f) Density of bitumnious concrete after compaction will be not less than 2.30 gm/CC.

Providing and laying bituminous concrete 30mm to 45mm thick with batch type hot mix plant using crushed aggregates of specified grading, premixed with bituminous binder VG-40 @ 5.4%, 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 compactioncomplete as per technical clause 507 of MORT&H specifications NOTES (i) Job mix formula for the bituminous concrete shall be provided by the agency and shall be got approved from Punjab PWD B&R Research Laboratory Patiala before adoption at site for execution. (ii) The specification of this item for analytic purpose is kept with bitumen content @ 5.40% weight of mix variation as compared with job mix formula shall be paid/deducted accordingly. The limits of variation shall be worked out with the approved formula TECHNICAL NOTE:- 1.)
