Challenge Problems
Push your limits with advanced challenges
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.
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.
