Show hintHide hint
Think about how soils are grouped based on their size.
Question 2.
What is compaction?
Show hintHide hint
What happens to the soil when it is compacted?
3Question 3.
What is the primary classification system used for soils in highway engineering?
- Unified Soil Classification System

Consider which system focuses more on highway applications.
4Question 4.
True or False: High plasticity index indicates good subgrade material.
- True
- False
Show hintHide hint
Think about what happens to soil with a high plasticity index.
Question 5.
A civil engineer measures a soil's Atterberg Limits as: Liquid Limit = 40%, Plastic Limit = 25%. Calculate the Plasticity Index and discuss its implications for pavement design.
Show hintHide hint
Remember the formula for PI.
Question 6.
A soil undergoes a plate load test and settles under a load intensity of 100 kPa, causing a 5mm settlement. Calculate the k-value and discuss its importance in rigid pavement design.
Show hintHide hint
Consider what high and low k-values mean for pavement performance.
