Try these first

1. 1.

   What does resilient modulus measure?

   Hint

   Think about how materials behave under repeated loads.

2. 2.

   Why is resilient modulus preferred over CBR in pavement design?

   Hint

   Consider the difference between a snapshot and ongoing behavior.

3. 3.

   What does resilient modulus indicate?

   • A measure of static soil strength
   • A measure of dynamic behavior under loads
   • A measure of permeability

   Hint

   Think of repeated traffic impacts over time.

4. 4.

   True or False: CBR is a better indicator of long-term pavement performance than resilient modulus.

   • True
   • False

   Hint

   Consider performance over time versus a single test result.

5. 5.

   Given soil samples with varying resilient modulus values, analyze how this affects their suitability for a new highway design.

   Hint

   Think about load capacities and strength.

6. 6.

   Design an experimental study aiming to assess the impacts of moisture and temperature on resilient modulus. What would your key variables be?

   Hint

   Consider environmental influences on soil behavior.
