2.2.1. Particle Size Distribution

Try these first

1. 1.

   What is Particle Size Distribution?

   Hint

   Think about why particle size is important.

2. 2.

   Which method do we use for particles larger than 75 micrometers?

   Hint

   Consider the word 'sieve' if it helps you remember.

3. 3.

   What does Particle Size Distribution refer to?

   • The range of soil colors
   • The range of particle sizes in soil
   • The weight of soil particles

   Hint

   Remember what PSD represents!

4. 4.

   True or False: Well-graded soils generally provide better drainage than poorly graded soils.

   • True
   • False

   Hint

   Think about how water moves through soil.

5. 5.

   Given a soil sample shows gaps in particle size distribution, what implications does it have for construction stability?

   Hint

   Consider how each size contributes to the overall stability of a structure.

6. 6.

   Explain the primary factors to consider when analyzing PSD for a specific construction project.

   Hint

   Link the analysis back to practical construction requirements.
