1. LECTURE 17

Try these first

1. 1.

   What is compaction in soil mechanics?

   Hint

   Think about what happens when you compress something.

2. 2.

   Explain what void space means.

   Hint

   Consider what fills the empty areas between soil particles.

3. 3.

   What does compaction in soil mechanics aim to achieve?

   • Decrease soil density
   • Increase soil density
   • Change soil texture

   Hint

   Consider the purpose of compressing soil.

4. 4.

   True or False: The Standard Proctor Test is used to determine the maximum swell potential of a soil.

   • True
   • False

   Hint

   Reflect on what the test measures.

5. 5.

   If you have two soil samples, one compacted dry of optimum and the other at optimum moisture content, compare their expected swell pressures.

   Hint

   Consider how moisture changes particle behavior.

6. 6.

   Design a test plan for a construction site requiring stability in wet conditions. Discuss how the Modified Proctor Test can be applied.

   Hint

   Think about how to adjust testing parameters for real-world conditions.
