4.2.4. Soil Structure and Fabric

Try these first

1. 1.

   What does soil structure refer to?

   Hint

   Think about how particles are organized in space.

2. 2.

   Why is soil cohesion important?

   Hint

   Consider how particles interact with each other.

3. 3.

   What factor significantly impacts soil strength related to particle arrangement?

   • Moisture Content
   • Soil Structure
   • Temperature

   Hint

   Think about what arrangement means.

4. 4.

   True or False: Cohesion decreases soil strength.

   • True
   • False

   Hint

   What holds the soil together?

5. 5.

   Given a scenario where a road built on poorly structured soil has begun to crack, create a detailed plan on how to evaluate the soil structure and suggest possible improvements.

   Hint

   Consider the tests we discussed in class to evaluate soil.

6. 6.

   Evaluate the role of soil bonding in determining the strength of subgrade soils under fluctuating moisture conditions.

   Hint

   Reflect on how moisture interacts with particle forces.
