5.2.2. Mechanical Properties

Try these first

1. 1.

   What does ACV stand for?

   Hint

   Consider what it measures regarding aggregates.

2. 2.

   What does a low AIV indicate?

   Hint

   Think about reactions to sudden forces.

3. 3.

   What does ACV measure?

   • Impact resistance
   • Crushing strength
   • Abrasion resistance

   Hint

   Focus on what sort of forces are applied.

4. 4.

   A higher AIV means better impact resistance.

   • True
   • False

   Hint

   Remember the relationship between AIV values and performance.

5. 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.

   Hint

   Consider the real-life applications of trucks and highways.

6. 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?

   Hint

   Think about which properties are more critical for structural longevity.
