Challenge Problems
Push your limits with challenges.
Question 1
You have two aggregate samples: Sample A with an FI of 10% and EI of 12%, and Sample B with an FI of 20% and EI of 30%. Which sample would you recommend for high-load pavement, and why?
💡 Hint: Think about how shapes affect pavement stability.
Question 2
