2 cards from this section. Quick, good the night before a test.
What happens to soil strength as compaction increases?
Think about how tightly packed soil affects its stability.
Define Optimum Moisture Content (OMC).
It's about finding the 'sweet spot' for moisture in soil.
Higher compaction levels typically result in what effect on soil strength?
Think about how pressure packs soil particles closer together.
True or False: The optimum moisture content is unimportant for achieving maximum soil strength.
Reflect on how moisture affects packing and bonding in soil.
You are designing a pavement over varying soil types. Describe the considerations you must take regarding compaction levels and moisture content.
Think about the characteristics of clay vs. sand under compaction.
Evaluate the consequences of neglecting compaction and OMC in a full-scale pavement project.
Consider what happens over time with poorly supported pavements.
