Challenge Problems
Push your limits with advanced challenges
You are tasked with constructing a roadway. How would you decide on using a soil with large or small particles? Discuss the trade-offs involved in relation to permeability and compaction.
💡 Hint: Think about the needs of your engineering project.
Analyze how different compaction techniques might alter the permeability of a given soil type with larger particles. What experimental approach could you use to quantify this effect?
💡 Hint: Consider lab testing methods like constant head or falling head permeability tests.
