Abstract
According to the problems that face the Indian highway system, a significant portion of the roads face long-term wear, creep, and rutting of the asphalt layers. These distresses may be occurred due to the shortage in the mechanistic properties of either of the binder and/or the asphalt mixtures as well as the increasing of traffic loads. In order to avoid earlier damage and failure, this study compares steel fiber modified hot mix asphalt mixtures with standard mix to examine how well they function. An experimental programme was designed and put into place to achieve this goal. Six HMA combinations were tested, including control mixtures, with steel fiber contents of 0.25%, 0.5%, 0.75%, 1%, 1.25%, and 1.5% by weight to the aggregate of HMA. In this study, the steel fibers were chosen as additive in hot asphalt mixtures for its good tensile strength, durability, ductility, stiffness and flexural properties. In addition, the interface between steel fiber and asphalt concrete has a high bonding strength. Performance of the different hot asphalt mixes was evaluated using the Marshall and ITS tests. The scope of the study included studying the performance of both unmodified and modified mixtures by steel fibers. The results of the investigations indicated that the addition of 1% steel fiber by aggregate weight improved the Marshall stability, flow, Marshall quotient, volumetric properties and the indirect tensile strength. The results also indicated that the addition of steel fiber did not improve the moisture susceptibility for all conditioning periods compared with control mixtures.
