4.3.1. Field Tests

Try these first

1. 1.

   What is the purpose of the California Bearing Ratio (CBR) test?

   Hint

   Remember the load-bearing aspect of pavement.

2. 2.

   What does the Plate Load Test assess?

   Hint

   Think about how it relates to rigid pavement design.

3. 3.

   What does the California Bearing Ratio (CBR) test measure?

   • Soil density
   • Soil support capacity
   • Soil moisture content

   Hint

   Think about the role of soil in supporting pavement.

4. 4.

   True or False: The results of the Dynamic Cone Penetration Test can be correlated with CBR values.

   • True
   • False

   Hint

   Recall connections between the tests conducted.

5. 5.

   Given a scenario where a CBR value of 15% is recorded. What recommendations would you provide for pavement thickness and why?

   Hint

   Consider the relationship between CBR and pavement thickness.

6. 6.

   You perform all three soil strength tests (CBR, Plate Load, DCPT) and get conflicting results. What steps can you take to resolve this and decide on the pavement design?

   Hint

   Coordinate data for a cohesive assessment.
