27.4.3. Correlations with other tests

Try these first

1. 1.

   What is the resilient modulus?

   Hint

   Think about how materials behave under pressure.

2. 2.

   Name the two empirical tests mentioned in this section.

   Hint

   Both of them relate to material strength.

3. 3.

   What is the primary use of the resilient modulus?

   • To measure material strength
   • To assess recovery from load
   • To evaluate fatigue cracking

   Hint

   Think about its function concerning loads applied.

4. 4.

   True or False: The California Bearing Ratio test directly measures the resilient modulus.

   • True
   • False

   Hint

   Reflect on the nature of the tests discussed.

5. 5.

   Given that your CBR test results indicate a value of 8, estimate the resilient modulus for the pavement material. Use established correlations for guidance.

   Hint

   Reach out to empirical correlations available in engineering literature.

6. 6.

   You are tasked with designing a test plan for a new pavement material. How would you incorporate both the CBR and triaxial test results in your design strategy?

   Hint

   Consider how each property's data feeds into the larger picture of pavement performance.
