Challenge Problems

Push your limits with challenges.

Question 1

Given a region with high temperature fluctuations and seasonal frost, design an initial pavement structure considering both asphalt and concrete options to mitigate the adverse effects discussed in this section.

💡 Hint: Balance material properties with environmental considerations.

Question 2

Assess the impact of inadequate drainage on a hypothetical pavement in a consistently rainy environment. What engineering solutions might counteract these negative effects?

💡 Hint: Think about how water can be managed both above and below the surface.
