1.2.1.1. Mechanical and Physical Tests

Try these first

1. 1.

   What does lime stabilization improve in soil?

   Hint

   Think about the main properties discussed.

2. 2.

   Is pH important in lime stabilization?

   Hint

   What pH level are we targeting?

3. 3.

   What is one main effect of lime stabilization on soil?

   • Increases plasticity
   • Decreases swelling
   • Reduces density

   Hint

   Think about the positive outcomes of lime treatment.

4. 4.

   True or False: The optimum lime content is determined by achieving a pH of 12.4.

   • True
   • False

   Hint

   Recall the pH target discussed.

5. 5.

   You have a soil sample with an initial pH of 12.00. How much lime must you add to reach 12.40?

   Hint

   Think about the relationship between lime percentage and pH increase.

6. 6.

   A soil has high organic content. Discuss how you would approach stabilization with lime.

   Hint

   Remember, scale back the initial lime amounts in sensitive soils!
