Pavement blocks are increasingly popular in construction due to their durability, versatility, and aesthetics. However, their conventional production process heavily relies on natural resources like sand, cement, and aggregates, raising sustainability concerns. The construction industry faces growing pressure to adopt eco-friendly practices that minimize environmental harm and conserve resources. This study explored using waste materials in making interlocking pavement blocks. It found that replacing some cement with bagasse ash, fly ash, and brick kiln dust improved compressive strength compared to traditional blocks after 28 days. Substituting some aggregate with crushed waste plastic slightly reduced tensile strength, particularly at 7 and 28 days, with lower replacement ratios performing better. Overall, using waste materials in pavement block production has the potential to promote sustainable construction by reducing environmental impact and costs, aligning with sustainable development principles and resource efficiency.
