Try these first

1. 1.

   What is soil modification?

   Hint

   Think about what purpose soil modification serves.

2. 2.

   Name a method of mechanical stabilization.

   Hint

   Consider how we might change the soil's physical characteristics.

3. 3.

   What is the main difference between soil modification and stabilization?

   • Modification impacts pavement design
   • stabilization does not.
   • Stabilization improves soil strength
   • modification does not.
   • Both are the same.

   Hint

   Remember their definitions.

4. 4.

   True or False: Mechanical stabilization involves only chemical treatments.

   • True
   • False

   Hint

   Consider the types of techniques involved with mechanical stabilization.

5. 5.

   You are tasked with designing a road section over a soft soil area. Discuss the factors you would analyze to choose between modification and stabilization methods.

   Hint

   Think about the characteristics that would lead to using one method over the other.

6. 6.
