Challenge Problems

Push your limits with challenges.

Question 1

A new pavement mix is proposed for a climate that experiences average winter lows of -10°C. What would be an appropriate plan to ensure the mix maintains sufficient low-temperature fracture toughness?

💡 Hint: Think about the environmental impacts on material performance.

Question 2

Given that climatic conditions can change, how could cyclic temperature changes affect fracture toughness and what testing regime would you recommend for a mix design subjected to frequent thawing and freezing?

💡 Hint: Consider the effects of temperature fluctuation on crack resistance.
