4Question 4.
PAV testing increases bitumen’s rigidity. True or False?
- True
- False
Show hintHide hint
Think about what happens to materials over time.
Question 5.
Consider a scenario where a new formulation of bitumen shows reduced stiffness in PAV testing. Discuss the possible implications for pavement performance.
Show hintHide hint
Think about how stiffness relates to performance under load.
Question 6.
