Challenge Problems
Push your limits with challenges.
Question 1
A road uses a visco-elastic material that exhibits a dynamic modulus of 500 MPa at a frequency of 10 Hz. How would this modulus change if the frequency increases to 20 Hz?
💡 Hint: Consider the relationship between frequency and material response.
Question 2
Propose a set of conditions that should be maintained during a dynamic modulus test to ensure accurate representation of traffic stress on pavement.
💡 Hint: Think about what real traffic conditions involve.
