1.1.5. Lubrication and Dense Packing

Try these first

1. 1.

   What is the relationship between water content and compacted density?

   Hint

   Think about how too much water might affect packing.

2. 2.

   Define MDD.

   Hint

   What does 'maximum' imply about density?

3. 3.

   What is the maximum density achieved by soil at a specific moisture content called?

   • Optimum Moisture Content
   • Maximum Dry Density
   • Particle Density

   Hint

   Which option includes 'maximum' and 'density' together?

4. 4.

   Increasing water content beyond OMC decreases compacted density. True or False?

   • True
   • False

   Hint

   What happens when too much water is present?

5. 5.

   Given two soil types, coarse gravel and fine clay, design a compaction strategy for a construction project site considering their moisture requirements.

   Hint

   Consider their compacting densities and moisture needs.

6. 6.

   Assess how varying compaction efforts can lead to different MDDs in a grading project. Provide examples.

   Hint

   What happens if you switch from a basic compactor to a heavy-duty one?
