1.4. Geotechnical Design Considerations

Try these first

1. 1.

   What is soil modification?

   Hint

   Think about a temporary measure used during construction.

2. 2.

   Name one chemical agent used in soil stabilization.

   Hint

   Consider materials that improve soil strength.

3. 3.

   What is the primary goal of soil stabilization?

   • To improve soil aesthetics
   • To enhance soil strength for load-bearing
   • To reduce moisture content

   Hint

   Think about the reasons for needing sturdy soil in construction.

4. 4.

   Soil modification can be considered a permanent solution.

   • True
   • False

   Hint

   Consider the longevity and impact of modifications.

5. 5.

   Analyze a scenario where a new highway must be constructed over a wetland area with soft soils. What stabilization methods would you recommend and why?

   Hint

   Reflect on both immediate and long-term benefits of methods.

6. 6.

   Evaluate the impact of using lime versus cement for chemical stabilization in clay soils. What factors would influence your decision?

   Hint

   Think about how different conditions might affect materials' options.
