24.3. Requirements of Bituminous mixes

Try these first

1. 1.

   What does stability in bituminous mixes refer to?

   Hint

   Think about how a pavement keeps its shape under pressure.

2. 2.

   Why is flexibility important in bituminous mixes?

   Hint

   Consider how pavement responds to vehicles driving over it.

3. 3.

   What is the primary focus of stability in bituminous mixes?

   • Flexibility
   • Durability
   • Resistance to deformation

   Hint

   Consider how pavement deforms under heavy loads.

4. 4.

   True or False: Flexibility is not important for preventing cracks.

   • True
   • False

   Hint

   Think about the effects of heavy vehicles on road surfaces.

5. 5.

   Evaluate a scenario where a pavement is failing due to low durability levels. What factors should be assessed?

   Hint

   Focus on how each factor can compromise the structural integrity of the pavement.

6. 6.

   Design a solution for a pavement that has poor workability. What changes could be made to improve this property?

   Hint

   Think about how the shape of materials affects their arrangement and compaction.
