Challenge Problems
Push your limits with challenges.
Question 1
A civil engineer has two soil samples: one with LL of 45% and PL of 20% and another with LL of 30% and PL of 15%. Calculate the PI for both and discuss their implications for road construction.
💡 Hint: Remember, a higher PI often indicates more problems for subgrade support.
Question 2
Considering a specific region prone to heavy rainfall, suggest modifications for construction practices if high PI soils are detected.
💡 Hint: Focus on methods to enhance soil performance under moisture stress.
