6.5.2. Abrasion Test

Try these first

1. 1.

   What is the purpose of the Abrasion Test?

   Hint

   What do we want to know about the aggregates?

2. 2.

   Name one standard that governs the Abrasion Test.

   Hint

   Think of Indian Standards related to aggregates.

3. 3.

   What does the Abrasion Test measure?

   • Durability of aggregates
   • Density of aggregates
   • Heat resistance

   Hint

   Consider the contexts in which we use aggregates.

4. 4.

   The acceptable abrasion value for wearing surfaces is:

   • 50%
   • 35%
   • 30%

   Hint

   Recall the standards for road aggregates.

5. 5.

   Evaluate a road construction proposal that uses aggregates with an abrasion value of 42%. What can you predict about the long-term performance of this road?

   Hint

   Consider how the wear impacts its usability over time.

6. 6.

   Design an aggregate selection strategy for a new highway project in a high-traffic area. What abrasion value would you prioritize, and why?

   Hint

   Think about the traffic loads expected.
