2.12.3. Applications

Try these first

1. 1.

   What is soil stabilization?

   Hint

   Think about improving soil strength.

2. 2.

   What role does the subgrade play in transportation?

   Hint

   It's the layer directly supporting the pavement.

3. 3.

   What is the primary purpose of soil stabilization techniques?

   • To enhance soil color
   • To improve soil strength
   • To increase soil volume

   Hint

   Think about why we want to improve soil for construction.

4. 4.

   True or False: A stable subgrade can lead to longer-lasting pavements.

   • True
   • False

   Hint

   Consider the impact of a strong foundation.

5. 5.

   Design a soil stabilization plan for a construction project in a wet region with clayey soils.

   Hint

   Consider the clay's properties and how to improve them for better performance.

6. 6.

   Analyze a situation where inadequate base layer stabilization leads to pavement failure. What steps could have been taken to prevent this?

   Hint

   Reflect on how each layer supports the pavement and affects performance.
