How to Know that veriation acceptable in CPWD Work Of 1:6 Cement Mortor Received Lab test report.

881As 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.

621Please send the graphical comparision Viscosity vs temp. for Penetration grade, Viscosity grade & CRMB.
