22.3.7. Bitumen adhesion test

Try these first

1. 1.

   What is the purpose of the bitumen adhesion test?

   Hint

   Think about the conditions affecting adhesion.

2. 2.

   What is the maximum allowed stripping value according to IRC?

   Hint

   Recall the limits we discussed.

3. 3.

   What is the main focus of the bitumen adhesion test?

   • To measure aggregate strength
   • To evaluate bitumen bonding
   • To assess moisture levels

   Hint

   Focus on the purpose of the test.

4. 4.

   True or False: Wet aggregates enhance the adhesion of bitumen.

   • True
   • False

   Hint

   Consider the effect of moisture.

5. 5.

   Design a testing procedure for a new aggregate type to assess its adhesion properties with bitumen.

   Hint

   Consider steps necessary for thorough testing.

6. 6.

   Evaluate the potential consequences for a road construction project if the adhesion between bitumen and aggregates is not properly managed.

   Hint

   Think long-term about maintenance and safety issues.
