Challenge Problems
Push your limits with advanced challenges
Design a laboratory testing protocol for a new type of environmentally friendly bituminous mix to assess its performance against conventional mixes.
💡 Hint: Think about which tests would show differences in performance.
Suppose you notice a mix has low results in dynamic modulus and high results in indirect tensile strength. What are the implications for pavement performance, and how might you adjust the mix design?
💡 Hint: Consider how mix changes affect the respective properties.
