1.9. Stabilization Requirements Based on Soil Classification

Try these first

1. 1.

   What is the primary purpose of soil stabilization in pavement engineering?

   Hint

   Think about the impacts of poor soil on pavements.

2. 2.

   Name one material used in chemical stabilization.

   Hint

   What can reduce plasticity in soil?

3. 3.

   What is chemical stabilization primarily used for?

   • To improve gradation
   • To reduce plasticity
   • To enhance load capacity

   Hint

   Focus on how soil behavior changes with added materials.

4. 4.

   True or False: Bituminous stabilization is used to increase soil flexibility.

   • True
   • False

   Hint

   Consider the effects of water on soil.

5. 5.

   A city is facing frequent pavement failures due to expansive clay soils. Propose a suitable stabilization method and justify your choice.

   Hint

   Consider how additives can alter soil characteristics.

6. 6.

   Evaluate the effectiveness of bituminous stabilization in a humid environment compared to dry conditions.

   Hint

   Look into how moisture levels impact soil behavior.
