Discussion
In a compaction test if the compacting effort is increased, it will result in :
Answer: D
Greater compactive effort gives an increase in maximum dry density and decrease in OMC.
Heavier compaction, as in the modified Proctor test compared with the standard test, pushes the particles closer together, so the soil reaches a higher maximum dry density. Because the extra energy does part of the work that water does as a lubricant, that peak is reached at a lower water content. The compaction curve moves upward and to the left, along the line of optimums.
So the maximum dry density does change, ruling out option A, and the optimum moisture content falls, ruling out B and C.
