Construction of embankment with approved materials deposited at site obtained from roadway cutting and excavation from drain and foundation or other structures graded and compacted to meet requirement of Tables 300-1 and 300-2 as per MoRTH Specification Clause 305.3

Compacting Original Ground Compacting original ground supporting subgrade Loosening of the ground upto a level of 300 mm below the subgrade level, watered, graded and compacted in layers to meet requirement of Tables 300-1 and 300-2 for subgrade construction as per MoRTH Specification Clause 305.3.4

Granular Sub-Base with Close Graded Material (Table:- 400-1) Plant Mix Method Plant Mix Method ,Providing laying spreading and compacting specified graded sand, gravel (crushed stone) as per Table 400-1,400-2 or any other course material as per design mix, as per CBR in sub base course including premixing the material at OMC in wet mix plant, carriage of mixed material spreading in uniform layers with notor grader F.E loader on a prepared base and compacting with vibratory roller to achieve desired density (as per I.S. 2720) including all material, labor, machinery, lighting guarding, barricading and maintenance of diversion complete [MoRTH specification : Clause 401]. By Mechanical means.For Grading I Material

Plant Mix Method Providing, laying, spreading and compacting graded stone aggregate to wet mix macadam specification including premixing the material with water at OMC in mechanical mixer (Pug Mill), carriage of mixed material by tipper to site, laying in uniform layers in sub-base/base course on a well prepared sub-base and compacting with smooth wheel roller of 80 to 100kN weight to achieve the desired density including lighting, barricading and maintenance of diversion, etc as per Tables 400-12 & 400-13 and MoRTH Specification Clause 406.By Mechanical Means with all leads.

Dry Lean Cement Concrete Construction of dry lean cement concrete Sub- base over a prepared sub-grade with coarse and fine aggregate conforming to IS: 383, the size of coarse aggregate not exceeding 25 mm, aggregate cement ratio not to exceed 15:1, aggregate gradation after blending to be as per table 600-1, cement content not to be less than 150 kg/ cum, optimum moisture content to be determined during trial length construction, concrete strength not to be less than 10 Mpa at 7 days, mixed in a batching plant, transported to site, laid with a paver with electronic sensor, compacting with 8-10 tonnes vibratory roller, finishing and curing.

Cement Concrete Pavement Construction of un-reinforced , plain cement concrete pavement M30 (Grade), thickness as per design, over a prepared sub base, with 43/53 grade cement as per Clause 602.2.2 , coarse and fine aggregates conforming to IS:383, maximum size of coarse aggregate not exceeding 25 mm, mixed in a in fully automatic Batching Plant and transported to site in transit mixer for having continous agitated mixer, manufactured as per approved mix design including pumping of R.M.C. from transit mixer to site of laying , with all lead and lift including cost of admixtures in recommended portion as per IS 9103 to accelerate/ retard setting of concrete, improve workability without impairing strength and durability as per direction of Engineer in charge laid in approved fixed side formwork (steel channel, laying and fixing of 125 micron thick polythene film, wedges, steel plates including levelling the formwork as per drawing), spreading the concrete with shovels, rakes, compacted using Fixed Form Paver and finished in continuous operation including provision of contraction and expansion, construction joints, applying debonding strips, primer, sealant near approaches to bridge/culvert and construction joints, admixtures as approved, curing of concrete slabs for 14-days using water finishing to lines and grade as per drawing and MoRTH Specification Clause 602 including vaccum dewatering process with all required equipments (Dowel Bars will be paid seprately).
