Question

In a compaction test if the compacting effort is increased, it will result in

• A. increase in maximum dry density and OMC
• B. increase in maximum dry density but OMC remains unchanged
• C. increase in maximum dry density and decrease in OMC
• D. no change in maximum dry density but decrease in OMC

Answer 1

The correct option is C increase in maximum dry density and decrease in OMC

The effect of increasing the amount of compactive effort is to increase the maximum dry density and to decrease the optimum water content (OMC).
