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.
