2. 2.

   Name one type of equipment used for soil compaction.

   Hint

   Think about small vs. large equipment!

3. 3.

   What is the optimal water content for effective soil compaction?

   • Above OMC
   • Below OMC
   • At OMC

   Hint

   Recall the laboratory technique we covered.

4. 4.

   True or False: Increasing lift thickness will generally improve compaction efficiency.

   • True
   • False

   Hint

   Think about our discussion on uniformity.

5. 5.
