Show hintHide hint
Consider what it measures regarding aggregates.
Question 2.
What does a low AIV indicate?
Show hintHide hint
Think about reactions to sudden forces.
3Question 3.
What does ACV measure?
- Impact resistance
- Crushing strength
- Abrasion resistance
Show hintHide hint
Focus on what sort of forces are applied.
4Question 4.
A higher AIV means better impact resistance.
- True
- False
Show hintHide hint
Remember the relationship between AIV values and performance.
Question 5.
You are tasked with determining which aggregates to use for a highway project that expects heavy truck traffic. Explain how you would evaluate the aggregates using ACV, AIV, and LAAV, citing the ideal values for each.
Show hintHide hint
Consider the real-life applications of trucks and highways.
Question 6.
Compare two aggregates: Aggregate A has an ACV of 25%, AIV of 15%, and LAAV of 28%. Aggregate B has an ACV of 32%, AIV of 18%, and LAAV of 25%. Which aggregate would you recommend and why?
