In this study, the mechanical properties and durability of rainwater penetration and retention pavement concrete blocks incorporating bottom ash fine aggregate were investigated to develop pavement concrete blocks that could reduce the rainwater leakage of impervious concrete structures. Pavement concrete blocks were prepared by replacing 0%, 10%, and 20% of the weight of natural fine aggregate with bottom ash fine aggregate for 410 and 450 kg/m<sup>3</sup> cement contents. Experimental tests were conducted to determine the compressive strength, flexural strength, abrasion resistance, slip resistance, freeze–thaw resistance, and permeability coefficient of the pavement concrete blocks. Pavement concrete blocks produced with a cement content of 450 kg/m<sup>3</sup> and a 10% replacement ratio of bottom ash fine aggregate satisfied the target performance and exhibited the best overall performance. Theseoptimal mix parameters were applied in this study to design and manufacture pavement concrete blocks for rainwater penetration and retention that satisfied the target performance.
