4 cards from this section. Quick, good the night before a test.
What does the Aggregate Crushing Value (ACV) measure?
Consider the performance of aggregates under heavy loads.
What is the maximum allowable water absorption percentage for road aggregates?
Think about how much moisture the aggregate can tolerate.
What is the maximum allowable Aggregate Crushing Value (ACV) for wearing surfaces?
Remember that lower values indicate better strength.
True or False: Flakiness Index must be less than 15% for surface courses.
Think about the requirement for aggregate shape.
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.
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?
Think about mixing different types of aggregates to satisfy the performance while adhering to budget constraints.
