Answer Posted / s k majumder
Meter Cubic wet volume = 1*1.52 =1.52 Meter Cubic dry vol.
= 1.52*35.33=53.70 cft
Hence for M-20 where nominal portion 1.1.5.3
Total volume comes to (1+1.5+3)= 5.5
Therefore Dry volume for one cubic meter.
Cement= 53.70/5.5=cft= 9.76cft= bag= 7.81 bag=8 bags
sand = 9.76*1.5=14.64 cft
stone = 9.76*3=29.28 ct

As per Kandal suggestions, we have implemented rolling starts on 140 (+/- 5) degrees and we kept 3 rollars to complete the rolling before falling 125 degrees and the Aggregate AIV is below 22. But When the DBM bed is being rolled 3rd high viabration, (Before 1 plain & low ,2 high Viabrations), the aggregate is getting sharp edge agg. projections are damaged. As the literature is said that, the VG-30 Grade having better control the temp. susceptibility than Penetration grade. if so we could not get this problem at site. But we are facing on site. let me know.
