3. 3.

   What is the primary purpose of soil stabilization?

   • To improve soil aesthetics
   • To enhance soil strength
   • To reduce soil density

   Hint

   Think about why construction workers might alter the soil's natural state.

4. 4.

   Chemical stabilization involves the use of what?

   • Mechanical tools
   • Chemical additives
   • Water

   Hint
