2.12.1. Need for Stabilization

Try these first

1. 1.

   What is soil stabilization?

   Hint

   Think about why we change soil properties before construction.

2. 2.

   Name one method of soil stabilization.

   Hint

   Consider the different types we discussed in class.

3. 3.

   What is the primary goal of soil stabilization?

   • A) To increase permeability
   • B) To enhance strength
   • C) To reduce construction costs

   Hint

   Think about how construction would be affected without stabilizing soil.

4. 4.

   True or False: Chemical stabilization can involve the use of lime or cement.

   • True
   • False

   Hint

   Recall the different methods of soil stabilization we discussed.

5. 5.

   Analyze a construction site with high plasticity clay soil prone to swelling. Propose a comprehensive stabilization strategy and justify your choice of methods based on the soil's properties and expected loads.

   Hint

   Consider both physical and chemical stabilization methods appropriate for the conditions.

6. 6.

   Evaluate the effectiveness of mechanical and chemical stabilization in a real-world scenario where construction costs are a concern. Discuss potential trade-offs between short-term savings and long-term performance.

   Hint

   Think about the long-term implications versus initial costs.
