Challenge Problems
Push your limits with challenges.
Question 1
A soil sample has W_L = 70%, W_P = 36%. It contains 40% clay. Calculate its plasticity index, activity, and liquidity index. Discuss its construction suitability.
💡 Hint: Make sure to substitute the correct values into the formulas.
Question 2
A construction site requires a soil that can handle rapid moisture changes. If you have two samples—Sample A with W_L = 45% and PI = 15%, and Sample B with W_L = 60% and PI = 35%—which do you choose and why?
💡 Hint: Evaluate the plasticity of each sample based on their PI.
