Interactive Quizzes
Engage in quick quizzes to reinforce what you've learned and check your comprehension.
Question 1
What is the relationship used to define resilient modulus?
- M_R = σ / ε
- M_R = σ_d / ε_r
- M_R = ε / σ
💡 Hint: Focus on the terminology used in the definition.
Question 2
True or False: Permanent deformation is always recoverable after a load is applied.
- True
- False
💡 Hint: Consider what happens to materials after heavy loads.

Challenge Problems
Push your limits with challenges.
Question 1
Consider a flexible pavement with a known resilient modulus of 200 MPa. If the deviator stress during a repeated load test is 50 kPa, calculate the recoverable strain.
💡 Hint: Reorganize the equation to isolate the recoverable strain.
Question 2
If a dynamic modulus test shows a complex modulus value of 400 MPa at a given frequency, discuss what factors could influence this value and suggest appropriate adjustments.
💡 Hint: Think of environmental conditions affecting material behavior.
