Abstract

This study discusses on studies on the use and effectiveness of waste steel fibre as an additive in modifying asphalt mixture to enhance rutting resistance. The objectives were to evaluate the influence of incorporating steel fibre on rutting behaviour by measuring the index of retained strength. Various amounts of steel fibre (0%, 1%, 2%, and 3%) were added to the asphalt mixture using the Superpave mix design method. Determining the optimum bitumen content resulted in identifying 5.5% bitumen content, which exhibited desirable performance characteristics. Performance tests were conducted to assess the impact of including steel fibre on rutting resistance and permanent deformation. Surprisingly, the results indicated that slightly including steel fibre improves rutting resistance or reduces permanent deformation. These findings suggest that adding waste steel fibre within the tested percentages can slightly enhance the rutting resistance or mitigate permanent deformation in the asphalt mixture. Further research and exploration are required to identify alternative approaches for improving the rutting resistance of asphalt mixtures.
