This This study investigates the effect of replacing coarse aggregate with flexible pavement waste on the compressive strength and water absorption of concrete. Different percentages of replacement (0%, 25%, 35%, and 45%) were tested to assess the mechanical properties of the concrete at 28 days of curing. The results revealed a notable decrease in compressive strength as the percentage of coarse aggregate replacement increased up to 25%, with the compressive strength at 25% replacement (16.4 N/mm²) significantly lower than that of the control mix (24.73 N/mm²). However, beyond 25% replacement, an improvement in strength was observed, with the 45% replacement yielding a compressive strength of 22.01 N/mm², higher than that at 35% replacement. Additionally, the water absorption percentage of flexible pavement waste (1.02%) was found to be lower than that of conventional coarse aggregate (1.74%), suggesting better moisture resistance and durability. Based on these findings, it can be concluded that a 45% replacement of coarse aggregate with flexible pavement waste offers the optimum balance between strength and sustainability. The observed difference in compressive strength between conventional and flexible pavement waste aggregate concrete at 28 days of curing was 11%, indicating the potential of flexible pavement waste as a viable alternative for sustainable concrete production.
