6.5. Aggregate Tests and Standards

Try these first

1. 1.

   What is the primary objective of the Crushing Strength Test?

   Hint

   Think about the loads that roads experience.

2. 2.

   What does the Abrasion Test measure?

   Hint

   Consider how aggregates perform under friction.

3. 3.

   What does the Crushing Strength Test assess?

   • Resistance to water
   • Resistance to crushing
   • Resistance to abrasion

   Hint

   Consider what happens when vehicles drive over the road.

4. 4.

   True or False: A good aggregate should have high abrasion values.

   • True
   • False

   Hint

   Think about the durability needed in road materials.

5. 5.

   How would you design a pavement for a heavily trafficked road using aggregate properties? Discuss the tests you would use.

   Hint

   Consider which properties would withstand heavy traffic best.

6. 6.

   If a new aggregate type shows high Water Absorption and high Flakiness Index, how would that affect your choice for a new road construction project?

   Hint

   Think about what these properties would mean for the road's overall strength.
