Abstract

This study aims to enhance sustainability, reduce environmental impact, minimize rutting, and improve performance by evaluating the use of construction material wastes. Ceramic waste powder (CWP), brick waste powder (BWP), and glass waste powder (GWP) were used as alternative fillers to conventional dolomite powder (DP) in hot-mix asphalt (HMA). The research investigates the effectiveness of these waste materials in improving asphalt performance, with the filler percentage fully replaced by these alternatives. Marshall Stability (MS), Marshall Quotient (MQ), moisture susceptibility, indirect tensile strength (IDT), and wheel tracking tests (WTT) were conducted to evaluate the impact of these waste materials on asphalt properties. Additionally, the results showed that MS improved with CWP and BWP by approximately 27% and 10%, respectively, compared to the control mix. In contrast, GWP led to a decrease in MS by about 28% compared to the control mix. In the (IDT) test, CWP and BWP mixtures demonstrated improvements of approximately 2.31% and 0.89%, respectively, compared to the control mix. Additionally, CWP significantly enhanced resistance to rutting, showing an improvement of about 30.38% compared to the control mix. Overall, CWP not only improved the mechanical properties of HMA but also provided a suitable solution for recycling these waste materials.
