Question 1.
What is flexible pavement?
Show hintHide hint
Think about how it responds to traffic.
Question 2.
Define empirical design.
Show hintHide hint
Focus on past experiences.
3Question 3.
What is flexible pavement designed to do?
- Deflect under loads
- Be rigid
- Have one material layer
Show hintHide hint
Focus on its characteristic feature.
4Question 4.
True or False: Empirical design does not use past data.
- True
- False
Show hintHide hint
Remember how empirical methods work.
Question 5.
Given a dual wheel assembly load of 3000 kg and a center-to-center distance of 20 cm at a depth of 30 cm, calculate the ESWL using the Boyd and Foster method.
Show hintHide hint
Keep in mind the logarithmic calculations while using the formula.
Question 6.
A pavement layer with a resilient modulus of 150 MPa has a constant traffic load of 1000 KN. Discuss how this modulus would influence the design of an additional layer.
Show hintHide hint
Consider how resilient modulus affects layer thickness.
