Challenge Problems
Push your limits with advanced challenges
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.
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.
