Performance evaluation of ceramic fiber modified asphalt mixtures using steel slag aggregates

Sustainability in pavement construction is very much required in the present scenario. Utilization of industrial waste as pavement material during construction is one of the methods for achieving sustainability. For the present study, Steel Slag and ceramic fibers were used as partial replacement of natural aggregate and as modifiers for binder respectively. SSA at 0, 20 40, and 60% total mix and ceramic additives at 0,3,5, and 7% were used. The rheological properties of the modified binder were studied using a Dynamic Shear Rheometer. Marshall stability test and moisture liability test were carried out to examine performance evaluation. Results show that the mix with 5% ceramic fiber with 60% SSA showed better performance compared to other mixes.
