Kamaal karte Hoon Main Batata Ho Aur Exact Nikal Ke Dikhata Hoon
Weight=area x thickness x density=LENGTH X AREA X DENSITY
densiy of steel=7850kG per m^3
area=(22 x d^2)/(7 X 4)=(PIE X D KA SQUARE)/ 4
LIS LENGTH
NOW WEIGT=(7850 X L X 3.14 X D^2) / 4
WEIGHT=(L X D^2 ) / (4/(3.14 X 7850))
WEIGHT= (L X D^2) / 0.0001618
NOW U KNOW IN CONVERT L INTO M AND D IN MM U WILL GET UR RESULT dia*dia/162.2
So i know its origin exactly

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.
