Challenge Problems

Push your limits with challenges.

Question 1

Using the layered elastic model, calculate the stress at the bottom of a pavement layer subjected to a given wheel load. Assume elastic properties for each layer are known.

💡 Hint: Remember to account for the depth and characteristics of each layer.

Question 2

Critique the reliability of the layered elastic model in a scenario where the material properties exhibit significant variation under different environmental conditions.

💡 Hint: Consider the reality of material responses to temperature changes or moisture.
