5.5.1. Laboratory Tests

Try these first

1. 1.

   What does UCS stand for?

   Hint

   Think about the strength measured without any support.

2. 2.

   What is CBR used for?

   Hint

   It's a test for road construction.

3. 3.

   What does a higher California Bearing Ratio (CBR) signify?

   • Poor load-bearing capacity
   • Enhanced load-bearing capacity
   • No impact on construction

   Hint

   Relate this to road performance.

4. 4.

   True or False: The Plasticity Index is a measure related to soil plasticity.

   • True
   • False

   Hint

   Think about how plasticity impacts workability.

5. 5.

   A construction site requires a soil with a minimum UCS of 200 kPa. If a test sample shows a UCS of 180 kPa, discuss what steps can be taken to meet the requirement.

   Hint

   What techniques do we use to enhance soil properties?

6. 6.

   Analyze the impact of a high Plasticity Index on the construction process. What potential issues might arise?

   Hint

   Think about how variations in moisture affect the usability of soil.
