14.5. Pavement Performance Under Weathering

Try these first

1. 1.

   What is ravelling?

   Hint

   Think about what happens to the top layer of pavement.

2. 2.

   What causes cracking in pavements?

   Hint

   Consider the impact of temperature changes.

3. 3.

   What is the primary cause of ravelling?

   • Weak binder
   • Heavy traffic
   • Cold weather

   Hint

   Think about what keeps the surface together.

4. 4.

   True or False: Bleeding is always beneficial for pavement performance.

   • True
   • False

   Hint

   Consider the conditions that arise.

5. 5.

   Construct a scenario where moisture-induced damage leads to severe rutting. Determine the chain of events and recommend preventive measures.

   Hint

   Consider traffic loads and environmental influences.

6. 6.

   Analyze the relationship between environmental conditions and the types of distress that occur in pavement surfaces.

   Hint
