For Slab-arround 75 kgs/Cum steel will consume.
ie Vol=Mass/Density
=75/7850
= .0095
For one Cum includes (Concrete and Steel)
ie =1-.0095
=.99 (Concrete)
Then ratio=.0095/.99
=.00955 X 100
=.95 (Ratio between concrete and steel)
For Beam-arround 130 kgs/Cum steel will consume.
ie Vol=Mass/Density
=130/7850
= .0165
For one Cum includes (Concrete and Steel)
ie =1-.0165
=.983 (Concrete)
Then ratio=.0165/.983
=.0167 X 100
=1.67 (Ratio between concrete and steel)
For Beam-arround 150 kgs/Cum steel will consume.
ie Vol=Mass/Density
=150/7850
= .0191
For one Cum includes (Concrete and Steel)
ie =1-.0165
=.98 (Concrete)
Then ratio=.0191/.98
=.0194 X 100
=1.94 (Ratio between concrete and steel)

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.
