2019-1-24 · The gradation mixes meant for component layers of flexible pavements have been subjected for compaction characteristics by performing modified proctor test as per IS 2720:(part 8-1983) and the results are shown in table and figure. From the test results, it is identified that if the size of the crushed stone particles is increasing OMC values are increasing and MDD values are also increasing, with respect to increasing the percentage of crusher dust. The same trend was continued up to 40% and then decrease in MDD and increase in OMC values were observed. The same phenomenon was observed with respect to all gradations of varying sizes of 75.00 mm, 53.00 mm, 26.5 mm, 12.5 mm -0.075 mm. Increase in dry densities are due to attainment of more solids of crushed stone and crusher dust particles in a given volume at a given compaction energy and obtainment of dense condition.
