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.
