Challenge Problems
Push your limits with challenges.
Question 1
A construction site needs to compact gravel with a lift thickness of 10 inches using a heavy roller. If the roller weighs 1500 lbs, explain how the weight affects the number of passes needed and potential adjustments if soil moisture is high.
💡 Hint: Consider the compaction guidelines for your soil type.
Question 2
