(MoRTH Specification : Clause 201). BY MECHANICAL MEANS In area of Thorney Jungle

Construction of sub-grade and earthen shoulders with approved Material obtained from borrow-pits with all lifts and leads, transporting to site, spreading, grading to require slope and compacted by vibratory roller 8-10 tonne to meet requirement of Table 300-2 as per MoRTH specification : Clause No. 305.

Providing, laying and spreading and compacting specified graded crushed stone in sub-base course including premixing the Material at OMC in mechanical mixer (Pug mill), carriage of mixed Material, laying in uniform layers with Motor Grader, F.E. Loader, on a prepared surface and compacting with Vibratory Compactor to achieve the desired density including all Material, labour, machinery, lighting barricading and maintenance of Driversion complete. (MoRTH specification clause 401). with all lead & lift

Milling of distressed road pavement Milling of distress bitumenous layer upto 70mm depth in a single pass with suitable milling machine (capable of milling @ 200&300 sqm of area per hr) fitted with loading conveyer of loading the filled material directly on the trucks i/c hauling and stock pilling the reclaiming to bring to required specification to reuse with the approval of engineer - in - charge for safe disposal; with all leads and lifts complete in all respect as directly by Engineer - in- charge. *Note : The unutilized quality of reclaimed bituminous mix material shall be recovered.

Providing & laying DBM using the reclaimed to the extent of 30% cent of the required quanity after carrying out necessary checks and evaluation, adding fresh material including rejuvenation as required, grade, level and thickness, all as specified in clause 519. (5th revision) 2013 using bitumen of VG-30 (minimum bitumen's 4.50% i/c bitumen retrieved material as per job mix formula) using 100-200 TPH batch type hot mix plant with approprite arrangement for use of R.A.P. appropriable rollars and with hydraulic paver finisher with sensor control to the required grade. If bitumen required more than 4.50% as per job mix formula no extra payment will be paid extra bitumen required will be considered as incidental to work.

Recovery of material obtained from dismantling of existing bituminous layer has been calculated taking assumption that 80% of the theoretical material will be retrieved. The dismantling material can be used in any other item for the work after modification (bringing it to required specification) after approval from the employer. In case it is not possible to use this material on the work, the agency can take away this material. Assuming recovery of 20% residue of Bitumen.
