Exploring activated carbon as an alternative to SBS in asphalt mixtures: Performance and fatigue analysis

Alexandria Engineering Journal
Fatigue cracking in hot mix asphalt (HMA) is a critical issue in flexible pavement maintenance, often leading to premature failure. Traditional fatigue tests are time-consuming and require significant manual effort.
