Laying of BT Road approaching to Admin building and around NTR statue in Spmvv , Tirupati.;Picking the existing B.T. surface and removal of chips.

Laying of BT Road approaching to Admin building and around NTR statue in Spmvv , Tirupati.;Providing and applying tack coat with bitumen emulsion (Rapid setting) at the rate of 0.20 kg per sqm using emulsion pressure distributor, on the prepared bituminous / granular surface cleaned with mechanical broom and Air compressor 250 cfm etc.,as per Technical specification No. 503 MORTH as directed by Engineer-in-charge during execution.

Laying of BT Road approaching to Admin building and around NTR statue in Spmvv , Tirupati.;Providing and laying Bituminous concrete of specified thickness by Hot mix plant 100-120 TPH capacity using bitumen of grade VG30, IRC size HBG crushed stone aggregates of specified grading, premixed with bituminous binder and filler(Quarry rubbish) conforming to Table 500-17 & Table 500-9, transporting the hot mix to work site, laying with a mechanical paver finisher to the required grade, level and alignment rolling with smooth wheeled 8-10 tonne, vibratory 8-10 tonne and tandem 6-8 tonne rollers to achieve the desired compaction as per Specification vide Clause No.507 of MORTH (5th Revision) etc., complete in all respects and as directed by the Engineer-in-charge during execution. unit=cum Taking output = 191cum (450 tonnes) Note : 1. Although the rollers are required only for 3 hrs as per norms of output, but the same have to be available at site for 6 hrs as the Hot mix plant and paver will take six hours for mixing and paving the output of 450 tonnes considered in this analysis. To cater for the idle period of these roller there usage rates have been multiplied by a factor of 0.65. 2. Quantity of Bitumen has been taken for analysis purpose. The actual quantity will depend upon job mix formula. 3. Labour for traffic control, watch and ward and other miscellaneous duties at site including sundries have been included in administrative overheads of the contractor. 4.

The individual density for each size of aggregates to be used for construction i.e.,37.5-25 mm, 25-10 mm etc., should be found in the laboratory and accordingly the quantities should be amended for use in field. The average density of 1.5 tonne/cu.m is only a reference density in this Data Book. 6. The individual percentage of aggregates should be calculated from the total weight of dry aggregates I.e., excluding the weight of bitumen. The weight of filler will also be 2 per cent by weight of dry aggregates. Gr-II
