Try these first

1. 1.

   What is the purpose of bituminous mix design?

   Hint

   Think about pavement characteristics.

2. 2.

   Name one component of a bituminous mix.

   Hint

   They provide strength.

3. 3.

   What is the primary objective of bituminous mix design?

   • To ensure low cost
   • To enhance pavement performance
   • To choose aesthetic materials

   Hint

   Focus on performance.

4. 4.

   True or False: The Superpave method uses a Marshall Hammer for compaction.

   • True
   • False

   Hint

   Recall the compaction techniques used.

5. 5.

   Calculate the Optimum Binder Content (OBC) if given stability values at different binder contents, demonstrating how to determine the point of optimal performance.

   Hint

   Consider the range of stability values.

6. 6.

   Evaluate the effectiveness of a bituminous mix that uses 20% recycled material. Discuss the economic and environmental impacts.

   Hint

   Think about balance in performance vs. sustainability.
