3.1. Objectives of Soil Compaction

Try these first

1. 1.

   What is the main purpose of soil compaction?

   Hint

   Think about how density affects structures.

2. 2.

   Name one benefit of reducing permeability through compaction.

   Hint

   What happens during heavy rains?

3. 3.

   What is one objective of soil compaction?

   • Increase air voids
   • Improve shear strength
   • Decrease density

   Hint

   Focus on what compaction does to soil properties.

4. 4.

   True or False: Reducing permeability is a goal of soil compaction.

   • True
   • False

   Hint

   Think about what good compaction prevents in terms of moisture.

5. 5.

   Analyze a case where highway construction failed due to inadequate soil compaction. What were the indicators, and how could it have been prevented?

   Hint

   Consider how engineering protocols play a role in construction success.

6. 6.

   Develop a set of recommendations for a construction project in a cold climate concerning soil compaction practices. Justify your recommendations.

   Hint

   Think about the effects of winter conditions on construction.
