Challenge Problems
Push your limits with challenges.
Question 1
Predict how a 20% increase in traffic load might influence the Resilient Modulus of a soil with initial Mr value of 1200 psi, assuming the soil's elastic properties remain unchanged.
💡 Hint: Evaluate the balance of stress and strain.
Question 2
A soil tests show Mr values of 800 psi in dry conditions and 650 psi in wet conditions. How should this influence pavement design considerations?
💡 Hint: Consider how moisture changes the behavior of soils.
