Question 1.
What is shear strength?
Show hintHide hint
Think about how soil holds weight.
Question 2.
How does compaction affect voids in soil?
Show hintHide hint
More compacted soil means less air.
3Question 3.
What effect does compacting clay soil wet of optimum have?
- Increases density
- Decreases permeability
- Increases shear strength
Show hintHide hint
Think about how moisture affects structure.
4Question 4.
True or False: Increased dry density always leads to reduced shear strength.
- True
- False
Show hintHide hint
Consider the particle contact concept.
Question 5.
Given a soil layer with varying moisture contents, analyze how the density and structure would differ between dry of optimum and wet of optimum conditions.
Show hintHide hint
Consider how moisture influences the arrangement of particles.
Question 6.
Evaluate a construction plan that involves compacting clayey soil. Identify methods to optimize shear strength during compaction.
