6.1.6. Adhesion with Bitumen

Try these first

1. 1.

   What is the primary test for assessing adhesion between aggregates and bitumen?

   Hint

   Think about the term that involves being submerged.

2. 2.

   Name one common anti-stripping agent used in road construction.

   Hint

   It's a common product used in different industries.

3. 3.

   What is the main purpose of adhesion in road construction?

   • To hold aggregates together
   • To add weight to the pavement
   • To improve aesthetics

   Hint

   Think about what happens when water touches the road.

4. 4.

   True or False: Stripping occurs when bitumen effectively bonds with aggregates.

   • True
   • False

   Hint

   Consider what happens when materials fail to stick.

5. 5.

   Consider a recently paved road showing early signs of stripping. Design a study to pinpoint adhesion failures and recommend solutions.

   Hint

   What steps would you take to assess the current materials?

6. 6.

   Evaluate the cost-benefit of introducing anti-stripping agents in a major highway project for a region with heavy rainfall.

   Hint

   Consider both short-term expenses and long-term benefits.
