A resilient modulus test shows that a pavement material experiences a deviator stress of 450 kPa with a recoverable strain of 0.0023. Calculate the resilient modulus and discuss the implications for pavement design.
💡 Hint: Apply the resilient modulus formula directly.
Discuss how traffic-induced loading variations would affect the resilient modulus in practical settings and propose methods to account for these variations in pavement design.
💡 Hint: Think about realistic load testing and statistical modeling.
