Question 1

What is the maximum allowable Aggregate Crushing Value (ACV) for wearing surfaces?

  • 30%
  • 40%
  • 20%

💡 Hint: Remember that lower values indicate better strength.

Question 2

True or False: Flakiness Index must be less than 15% for surface courses.

  • True
  • False

💡 Hint: Think about the requirement for aggregate shape.

Challenge Problems

Push your limits with challenges.

Question 1

Given that a new pavement requires aggregates with a maximum AIV of 25% and an ACV of 35%, list the types of aggregates that best suit this requirement and justify your reasoning based on their properties.

💡 Hint: Consider aggregates with both high strength and minimal impact.

Question 2

A project specifies that a mix must have a Flakiness Index above 25% for economic reasons, but the structure calls for high durability. How can you address these conflicting requirements?

💡 Hint: Think about mixing different types of aggregates to satisfy the performance while adhering to budget constraints.
