24.5. Problems

Try these first

1. 1.

   What is stability in bituminous mixes?

   Hint

   Think about how pavement behaves under traffic loads.

2. 2.

   Define durability.

   Hint

   Consider environmental factors affecting pavement longevity.

3. 3.

   What is stability in bituminous mixes?

   • Resistance to weathering
   • Resistance to deformation
   • Resistance to skid

   Hint

   Consider what happens during heavy traffic.

4. 4.

   True or False: Higher binder content always leads to better flexibility.

   • True
   • False

   Hint

   Think about too much of a good thing.

5. 5.

   Consider a pavement designed for high-speed traffic. Discuss how you would ensure sufficient skid resistance and stability in your mix design.

   Hint

   Think about how traffic speed affects safety and material properties.

6. 6.

   Evaluate the impact of varying binder content on the flexibility and durability of a mix over time. How would you approach finding the right balance?

   Hint

   Evaluate both short-term and long-term performance metrics.
