1.2. Importance of Soil Classification in Pavement Design

Try these first

1. 1.

   What is load-bearing capacity?

   Hint

   Think about what underlies the pavement.

2. 2.

   Why is soil classification important?

   Hint

   Consider how it contributes to stability.

3. 3.

   What does soil classification help determine?

   • Load-bearing capacity
   • Pavement aesthetics
   • Traffic volume

   Hint

   Think about its role in structural integrity.

4. 4.

   True or False: All soils are suitable for pavement design.

   • True
   • False

   Hint

   Recall the importance of soil stability in design.

5. 5.

   A pavement project is proposed on a site with varying soil types, including clay, silt, and well-graded sand. Discuss how each soil type affects the design and what considerations should be made for drainage.

   Hint

   Think about soil behaviors under load and interaction with water.

6. 6.

   You assess a site and find that it's primarily composed of expansive clay. What immediate steps and considerations should you take in your pavement design process?

   Hint

   Evaluate the soil’s behavior closely to reveal its challenges.
