Challenge Problems
Push your limits with advanced challenges
A new bituminous mix shows a complex modulus of 15 kPa and a phase angle of 10°. Based on these values, classify the mix as elastic or viscous. Justify your reasoning based on these parameters.
💡 Hint: Consider what low phase angles indicate about material properties.
An asphalt mix shows a dramatic increase in complex modulus at higher frequencies in a master curve plot. Discuss what implications this might have on the mix's performance in heavy traffic areas.
💡 Hint: Think about how materials respond to different loading conditions.
