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)

Durability Evaluation: Sustainable Semi-flexible Pavement Mixtures
IOP Conference Series: Materials Science and Engineering, 2021 Abstract The modern paving industry requires the production of high-performance pavement using more sustainable approaches. Semi-flexible pavement (SFP), prepared by filling an open-graded asphalt skeleton with cement-based grouting material, has been shown to offer high performance for heavily loaded highway and airport pavement ...
