Challenge Problems
Push your limits with challenges.
Question 1
A road consists of three uniform layers of asphalt, sub-base, and subgrade with elastic moduli of 3000 MPa, 1500 MPa, and 100 MPa, respectively. Calculate the stress distribution when a 60 kN load is applied at the surface.
💡 Hint: Remember to consider the thickness of each layer and the properties given.
Question 2
Discuss how varying the modulus of elasticity in one layer affects the overall performance of the pavement. Provide examples based on common materials used in flexible pavements.
💡 Hint: Think about the implications of changing properties and link back to the inputs and outputs segment.
