5. Soil Classification

Try these first

1. 1.

   What is the main purpose of soil classification?

   Hint

   Think about how engineers need to understand soil types.

2. 2.

   Name one method used to measure soil particle sizes.

   Hint

   We discussed several methods earlier in the lesson.

3. 3.

   What is the main purpose of soil classification in engineering?

   • To describe soil visually
   • To group soils by behavior
   • To measure soil strength

   Hint

   Consider the goal for engineers when they analyze soil.

4. 4.

   True or False: Soil description focuses solely on the chemical composition of the soil.

   • True
   • False

   Hint

   Think about what traits we use to describe soil.

5. 5.

   You have a soil sample with a grading curve. It shows that 90% of the particles pass through a 4.75mm sieve and 10% pass through a 0.075mm sieve. Determine the uniformity coefficient.

   Hint

   Think about how uniformity relates to particle distribution.

6. 6.

   In a hypothetical scenario, if soil characteristics indicate that all particles are of the same size, what challenges might arise in construction?

   Hint

   Consider how different particle sizes work together.
