14.2.2.3. Aggregate-Binder Adhesion

Try these first

1. 1.

   What is aggregate-binder adhesion?

   Hint

   Think about what keeps the pavement intact.

2. 2.

   What problem occurs from poor aggregate-binder adhesion?

   Hint

   What happens to pavement surfaces when water gets involved?

3. 3.

   What is the primary consequence of poor aggregate-binder adhesion?

   • Stripping
   • Ravelling
   • Cracking
   • All of the above

   Hint

   Think about how water interacts with the pavement.

4. 4.

   True or False: Polymer-modified bitumen can enhance aggregate-binder adhesion.

   • True
   • False

   Hint

   Consider how modifications change properties.

5. 5.

   Given specific conditions in a high-traffic region, design a pavement using your knowledge of aggregate-binder adhesion. Include material types and construction techniques.

   Hint

   Recall factors that affect adhesion and choose materials accordingly.

6. 6.

   Critique a case study where pavement failure occurred due to inadequate adhesion. Discuss what measures could have been implemented to prevent this.

   Hint

   Evaluate the link between material properties and performance.
