Practice Questions

Test your understanding with targeted questions related to the topic.

Question 1

Easy

What are the critical locations in a flexible pavement where strains are assessed?

💡 Hint: Think about where the binder and sub-grade are located in the pavement.

Question 2

Easy

What happens if tensile strains exceed the allowable limits?

💡 Hint: Consider what tensile strains can cause to the pavement layer.

Challenge Problems

Push your limits with challenges.

Question 1

Given a scenario where the tensile strain at the bottom of the bituminous layer reaches 300 microstrain, calculate the expected number of load repetitions permitted before significant fatigue cracking occurs using the criteria provided.

💡 Hint: Refer to the fatigue criteria equation described in the section.

Question 2

Imagine a flexible pavement designed for a high-traffic urban area. Draft a plan detailing how you would manage both tensile and compressive strains over its lifespan.

💡 Hint: Consider traffic analysis data along with the pavement design specifications.
