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)

EVALUATION OF SEMI-FLEXIBLE PAVEMENT PERFORMANCE [PDF]
Journal of Al-Azhar University Engineering Sector, 2020 This study aims at characterization and design new special type of asphalt mixture havinglower asphalt content and higher rutting resistance to be used in paving surface layers atheavy loads areas. To achieve this objective, grouting technique of permeable open gradedasphalt mixtures was used. Such type of pavement is called as a semi-flexible pavement
