What happens to soil density when water content increases?
Remember the peak density concept.
Define MDD.
Think about what 'maximum' means.
What is the relationship between water content and density?
Think about what happens after reaching OMC.
Is it true or false that increased compaction always results in higher density?
Consider how different soils react to the same compaction.
A construction site is observing a density drop after OMC is reached. What adjustments could engineers make to improve stability?
Think about prior topics discussed regarding compaction and moisture.
Why might coarse-grained soil be preferred in a high-traffic area, while fine-grained soil could be avoided?
Consider the moisture retention qualities of different soil types.
