QUESTION
Objective Question
With the increase in amount of compaction energy
Answer
( Option A)
optimum water content decreases, but maximum dry density increases
Solution
1. Maximum Dry Density (MDD) Increases
· Higher compaction energy causes soil particles to rearrange into a denser configuration.
· More air is expelled from the soil voids.
· Consequently, the maximum dry density increases.
2. Optimum Moisture Content (OMC) Decreases
· At higher compaction energy, less water is required to achieve maximum dry density.
· Therefore, the optimum moisture content decreases.
