3.3.3. Results Interpretation

Try these first

1. 1.

   What does the compaction curve plot?

   Hint

   Think about the two important properties of soil.

2. 2.

   What do OMC and MDD stand for?

   Hint

   They are key terms related to soil compaction.

3. 3.

   What does the peak of the compaction curve represent?

   • The moisture content only
   • The OMC and MDD
   • The type of soil

   Hint

   Think about what crucial values we derive from this peak.

4. 4.

   True or False: Too much moisture during soil compaction can enhance compaction quality.

   • True
   • False

   Hint

   Consider how moisture influences density.

5. 5.

   A construction project must compact soil at a moisture content of 15%. The tested OMC is 12%. Predict possible outcomes and suggest a solution.

   Hint

   Consider how moisture content relates to optimal compaction.

6. 6.

   Discuss the consequences of consistently ignoring the MDD during soil operations in a highway construction project.

   Hint

   What physical issues could arise from poor compaction?
