Show hintHide hint
Think about the states of moisture in soil.
Question 2.
What is the significance of a high Plasticity Index?
Show hintHide hint
Consider how moisture affects soil behavior.
3Question 3.
What does the Plasticity Index signify?
- Soil cohesion
- Soil expansion potential
- Soil compaction rate
Show hintHide hint
Think about how soil changes with moisture.
4Question 4.
True or False: A higher Plasticity Index always indicates better soil for pavement subgrade.
- True
- False
Show hintHide hint
Consider what high PI indicates regarding volume changes.
Question 5.
Evaluate a pavement design scenario with high moisture retention in the subgrade due to expansive soils. Suggest treatments and their rationale.
Show hintHide hint
Consider both chemical and physical methods for intervention.
Question 6.
In a case study, a highway constructed on high PI soils experienced cracking after heavy rains. How could the original design have integrated PI considerations?
Show hintHide hint
Look into pre-emptive design changes that ensure durability.
