4.3.2. Laboratory Tests

Try these first

1. 1.

   What does UCS stand for in soil testing?

   Hint

   Think about what it measures.

2. 2.

   What is the primary purpose of the CBR test?

   Hint

   It compares soil strength against a standard.

3. 3.

   What is the UCS Test used for?

   • Soil density measurement
   • Cohesive strength evaluation
   • Moisture content analysis

   Hint

   It's a test of strength without lateral confinement.

4. 4.

   True or False: CBR values provide information on subgrade soil strength?

   • True
   • False

   Hint

   Think about what CBR compares against.

5. 5.

   Given a UCS result of 80 kPa for a cohesive soil, predict potential pavement issues and suggest improvement methods.

   Hint

   Consider soil behavior under traffic loads.

6. 6.

   Explain how results from the Triaxial Compression Test could influence pavement thickness recommendations.

   Hint

   Think about how these factors determine necessary support.
