6.2.3. Based on Shape

Try these first

1. 1.

   What type of aggregates are found in riverbeds?

   Hint

   Think about the smoothest type.

2. 2.

   Which aggregates are characterized by sharp edges?

   Hint

   Consider the type that interlocks better.

3. 3.

   Which type of aggregates is preferred for high performance in pavements?

   • Rounded
   • Angular
   • Flaky
   • Cubical

   Hint

   Think about interlocking ability for high-load applications.

4. 4.

   True or False: Flaky aggregates help improve pavement stability.

   • True
   • False

   Hint

   Consider the shape's influence on strength.

5. 5.

   A small town plans to pave a low-traffic road. Discuss whether to use flaky aggregates and your reasoning.

   Hint

   Consider the traffic conditions and pavement purpose.

6. 6.

   Debate the benefits and limitations of using cubical aggregates in a high-load pavement versus using angular aggregates.

   Hint

   Think about how each shape influences performance.
