What does AIV stand for?
Show hintHide hint
Think about what kind of test we're discussing.
Question 2.
What is the significance of having a lower AIV?
Show hintHide hint
Consider how it affects pavement performance.
3Question 3.
What does a lower Aggregate Impact Value indicate?
- Higher impact resistance
- Lower impact resistance
- No effect on performance
Show hintHide hint
Remember how we measure the AIV value.
4Question 4.
The AIV test measures the resistance to which type of load?
- True
- False
Show hintHide hint
Think about what we covered in class.
Question 5.
You have performed the AIV test on three aggregates with following results: Aggregate A has AIV of 15%, Aggregate B has AIV of 22%, and Aggregate C has AIV of 10%. Which aggregates are suitable for use in concrete pavements, and why?
Show hintHide hint
Recall the standards for aggregate suitability in pavement.
Question 6.
Discuss the implications of using an aggregate mix with high AIV values in a concrete structure exposed to heavy machinery. What could happen over time?
Show hintHide hint
Consider the real-world environments where concrete is placed.
