Challenge Problems
Push your limits with challenges.
Question 1
Given a soil type with a starting void ratio of 0.8, calculate the new void ratio after compaction that doubles the soil density, assuming no change in volume.
💡 Hint: Consider the formula density = mass/volume and how void ratio relates to the volume of solids and voids.
Question 2
Evaluate how changing the moisture content during compaction of a clayey soil impacts its long-term consolidation settlement.
💡 Hint: Think about how the state of water affects clay particle arrangements.
