14.5.1.1. Ravelling

Try these first

1. 1.

   What is ravelling?

   Hint

   Think about what happens when the pavement surface deteriorates.

2. 2.

   Name a factor that can cause binder weakness.

   Hint

   Consider natural elements or physical exertion.

3. 3.

   What causes ravelling in bituminous pavements?

   • A strong binder
   • Weak binder adhesion
   • Good aggregate quality

   Hint

   Think about what happens when the binder does not perform well.

4. 4.

   True or False: Ravelling only affects low-traffic pavements.

   • True
   • False

   Hint

   Consider the conditions under which pavements are used.

5. 5.

   Evaluate the role of climate on pavement lifespan considering ravelling.

   Hint

   Analyze the conditions in various regions and their effect on materials.

6. 6.

   Design a hypothetical pavement system aimed at minimizing ravelling under high traffic conditions.

   Hint

   Innovate or use modern materials and techniques focused on durability.
