9.1. Coarse grained soil behavior.

Try these first

1. 1.

   What is the primary purpose of adding admixtures to soils?

   Hint

   Think of how admixtures affect stability.

2. 2.

   What happens to soil permeability when it is compacted?

   Hint

   Consider how water moves through compacted soil.

3. 3.

   What is the function of admixtures in soil?

   • To reduce moisture
   • To increase stability
   • To decrease density

   Hint

   Think about how admixtures enhance soil.

4. 4.

   True or False: Compaction increases soil permeability.

   • True
   • False

   Hint

   Consider the effect of density on permeability.

5. 5.

   A construction engineer is assessing a site with both fine and coarse soils. How would you approach the compaction process to ensure stability?

   Hint

   Consider the unique characteristics of each soil type.

6. 6.

   Given data shows that clay compacted dry of optimum experiences less settlement than the wet side. If a building is placed on this soil, how might this influence construction schedules?

   Hint

   Think about time-sensitive impacts of soil behavior.
