3.5.4. Aggregate Impact Value (IS: 2386 Part IV)

Try these first

1. 1.

   What does the Aggregate Impact Value test measure?

   Hint

   Think about how aggregates respond to sudden impacts.

2. 2.

   What is the acceptable aggregate impact value for pavement?

   Hint

   Recall the impact value specifics discussed.

3. 3.

   What does a high Aggregate Impact Value indicate?

   • High toughness
   • Low toughness
   • No impact on toughness

   Hint

   Think about toughness in aggregates.

4. 4.

   True or False: The maximum acceptable Aggregate Impact Value for wearing surfaces is 30%.

   • True
   • False

   Hint

   Recall the specifics of aggregate limits.

5. 5.

   A technician finds a batch of aggregates with an impact value of 32%. They are used in a high-traffic area. Evaluate whether they are suitable.

   Hint

   Consider the implications of surrounding conditions.

6. 6.

   Discuss the effect on safety and longevity if aggregates with an impact value of 50% are used in a major highway construction.

   Hint

   Think critically about quality control in engineering.
