6.3.3. Gradation Types

Try these first

1. 1.

   What is the definition of dense graded aggregates?

   Hint

   Think about how they impact road strength.

2. 2.

   Name one advantage of open graded aggregates.

   Hint

   Focus on their permeability.

3. 3.

   What is the main feature of dense graded aggregates?

   • High void content
   • Maximum density
   • Low permeability

   Hint

   Remember, they are designed for strength.

4. 4.

   True or False: Open graded aggregates are ideal for supporting high traffic loads.

   • True
   • False

   Hint

   Think about their primary purpose.

5. 5.

   Design a hypothetical pavement structure for a road requiring heavy traffic load management. Justify your choice of gradation type(s) and explain the expected performance outcomes.

   Hint

   Consider the traffic conditions and expected lifespan.

6. 6.

   Evaluate a scenario where using open graded aggregates might reduce the pavement life. Analyze the repercussions of inappropriate aggregate choice.

   Hint

   Think about the primary function of these aggregates.
