This study aims to investigate the influence of three typical gradation schemes, including continuous gradation, discontinuous and single on mechanical properties water permeability pervious concrete using recycled coarse aggregate (RCA) as aggregates. The changes in compressive strength, flexural failure mode, connected porosity, coefficient Recycled Pervious Concrete (RPC) different schemes correlations among these factors were investigated. results indicate that RPC prepared with RCA achieves optimal strengths 15.70 MPa 4.22 MPa, respectively. Furthermore, exhibits superior compared made RCA, its range can reach between 6.36 8.32 mm·s−1. multi-gradation is effective enhancing stability porosity coefficients. relationship coefficients be effectively characterized through nonlinear fitting, correlation R2 are 0.94, 0.92, 0.90, focuses several performance provides valuable data support for further optimization properties.
