24.3.1. Stability

Try these first

1. 1.

   Define stability in the context of bituminous mixes.

   Hint

   What does it protect against in pavement performance?

2. 2.

   Name one type of failure associated with unstable mixes.

   Hint

   Think of what happens under pressure or heavy traffic.

3. 3.

   What does stability in bituminous mixes refer to?

   • Resistance to deformation under load
   • Cost-effectiveness
   • Environmental impact

   Hint

   Think of what keeps a road intact despite heavy use.

4. 4.

   True or False: Increased binder always leads to better stability.

   • True
   • False

   Hint

   Consider the balance needed in the mix.

5. 5.

   Analyze a given pavement structure that continually experiences shoving. Propose a comprehensive mix design solution.

   Hint

   Consider the balance of materials and their properties.

6. 6.

   Given different aggregate sizes in a failed pavement, evaluate how grading and binder content could solve the stability issues.

   Hint

   Think about how different sizes interact.
