1.1. Mass, size

Try these first

1. 1.

   Define mass as it pertains to compactors.

   Hint

   Think about what mass relates to in force.

2. 2.

   What does relative compaction tell us?

   Hint

   Consider it a comparison metric!

3. 3.

   What factor primarily affects the force applied during soil compaction?

   • Operating frequency
   • Mass
   • Size

   Hint

   Consider what gives weight to the compactor.

4. 4.

   True or False: The size of a compactor has no impact on the depth of soil it compacts.

   • True
   • False

   Hint

   Think about how size impacts coverage.

5. 5.

   Calculate the optimal mass and size requirements for compacting clay and sandy soil in a new construction site, given their moisture content and density characteristics.

   Hint

   Refer back to the definitions of mass and size.

6. 6.

   Design a compacting schedule for a construction site that includes soil testing results for lifting thickness and multiple passes, factoring varying soil characteristics.

   Hint

   Base your design on the interactions between soil types and compaction goals.
