Fatigue Resistance and Cracking Mechanism of Semi-Flexible Pavement Mixture. [PDF]
Materials (Basel), 2021 Semi-flexible pavement (SFP) is widely used in recent years because of its good rutting resistance, but it is easy to crack under traffic loads. A large number of studies are aimed at improving its crack resistance. However, the understanding of its fatigue resistance and fatigue-cracking mechanism is limited. Therefore, the semi-circular bending (SCB)
