5. Relative compaction or degree of compaction

Try these first

1. 1.

   What is the role of mass in soil compaction?

   Hint

   Think about the effect of weight.

2. 2.

   Why is grain size important in compaction?

   Hint

   Consider how shapes fit together.

3. 3.

   What does increased mass of a compactor contribute to?

   • Less pressure
   • More pressure
   • No change

   Hint

   Think about weight and pressure.

4. 4.

   True or False: A higher frequency of operation improves compaction.

   • True
   • False

   Hint

   Recall how vibrations help.

5. 5.

   In a construction project, engineers must determine the optimal compactor size and mass for sandy soil to maximize compaction. What factors should they consider beyond just weight?

   Hint

   Think about all soil characteristics influencing compaction.

6. 6.

   Evaluate a scenario where a builder uses dry soil. Determine potential issues in compaction and suggest solutions.

   Hint

   Consider how moisture helps particles bond together.
