4 cards from this section. Quick, good the night before a test.
Define initial density in your own words.
Think about what happens to soil when it is compacted.
Why is water content important for soil compaction?
Consider how wet soil behaves versus dry soil.
What does initial density refer to?
Reflect on the definition we're discussing.
True or False: Finer soil particles typically result in lower initial density.
Think about how tight the particles fit together.
You have two types of soil: Type A (sandy and mostly round grains) and Type B (clay and angular grains). Which type do you predict will have a higher initial density when compacted, and why?
Think about how the shapes influence packing.
Design an experiment to test the effect of varying water content on the initial density of soil. What parameters would you control, and what method would you use to measure density?
Consider how you would keep other variables constant besides water.
