13.3.1. Aggregates

Try these first

1. 1.

   What are coarse aggregates?

   Hint

   Think about their size and role in load distribution.

2. 2.

   What is the role of fine aggregates?

   Hint

   Consider how puzzles fit together.

3. 3.

   What is the primary function of coarse aggregates?

   • Improve workability
   • Provide strength and load distribution
   • Fill micro-voids

   Hint

   Consider what supports the load in a pavement.

4. 4.

   True or False: Fine aggregates are larger than coarse aggregates.

   • True
   • False

   Hint

   Think about size comparison.

5. 5.

   Consider a hypothetical scenario where a pavement constructed with only fine aggregates fails under heavy traffic loads. Discuss the implications of not using coarse aggregates.

   Hint

   Reflect on why stability is crucial when using materials.

6. 6.

   Imagine you are designing a new pavement for a coastal city with high humidity. Discuss the aggregate selection strategy.

   Hint

   Think about environmental factors that influence material durability.
