2. Characteristics of the soil

Try these first

1. 1.

   Define the initial density of soil.

   Hint

   Consider weight relative to volume.

2. 2.

   What does grain size in soil refer to?

   Hint

   Think about how small or large soil pieces can be.

3. 3.

   What does initial density refer to?

   • Soil's moisture level
   • Soil's mass per unit volume
   • Soil's grain size

   Hint

   Focus on soil characteristics related to support.

4. 4.

   True or False: Grain shape has no influence on soil compaction.

   • True
   • False

   Hint

   Think about how pieces fit together.

5. 5.

   Given a construction scenario where water inflow increases soil saturation, predict how this affects load-bearing capacity and compaction methods.

   Hint

   Consider the analogy of adding water to sandcastle builds.

6. 6.

   Analyze a site with poorly graded soil and suggest appropriate engineering solutions to enhance its compactability.

   Hint

   Think about how mixing ingredients in baking can change the final product.
