Abstract: Steel fiber (SF) has been widely used in asphalt mixtures to provide efficient induction heating and improve performance. However, the application of SF in asphalt mixtures still faces the issues of mixing difficulty, ...

Abstract: Marginal hard asphalt possesses high stiffness and modulus; however, due to poor ductility at low temperature, it was seldom applied into road structures. Increasing asphalt content seemed to be an effective way to minimize ...

Abstract: In laboratory testing of asphalt mixtures, the relationship between the number of load repetitions and permanent deformation has been found to include three distinct stages, namely the primary, secondary and tertiary stages. ...

Abstract: The Superpave mix design is a process of repeatedly optimizing the aggregate gradation and asphalt content in accordance with specified limits. As one of the important design parameters, the number of design gyrations ...

Abstract: The modulus of the asphalt layer in a pavement structure subjected to vehicular loading is different from that subjected to falling weight deflectometer (FWD) loading. A comprehensive approach is developed in this study ...

Abstract: The modulus back-calculation of asphalt pavement layers using falling weight deflectometer (FWD) data has become one of the most important methods of evaluating pavement bearing capacity. Several back-calculation methods ...

Abstract: Brittleness has a significant influence on rock failure under compression; however, the mechanism is rarely comprehensively discussed. This study numerically investigates the brittleness effect on microcracking behavior ...

Abstract: The long-term durability of asphalt pavements is closely related to the oxidative aging of asphalt binders. Oxidative aging depends on the oxygen diffusion in asphalt mixtures. To further investigate oxidation reactions ...

Abstract: The determination of styrene-butadiene-styrene (SBS) content in SBS-modified asphalt (SBSMA) is crucial in road quality control. In this study, a polystyrene (PS)-based index, which is an alternative indicator for the ...

Abstract: An asphalt mixture has different tensile properties as compared with compressive ones due to the combined effect of aggregate interlock, binder stiffness, and aggregate-binder interactions. This study aims to investigate ...
