Challenge Problems
Push your limits with advanced challenges
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.
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.
