Cementitious porous pavement as a passive unit operation for rainfall-runoff control in the built environment

X. Kuang, J. Sansalone, J. Teng, L. Wang & J. Metcalf
Porous pavement is a structural low impact development (LID) material for rainfall-runoff control. In this study, pore characteristics of cementitious porous pavement (CPP) material, including total porosity (t), effective porosity (e), pore size distribution (PSD)pore, and tortuosity (are examined using x-ray tomography (XRT) and conventional gravimetric-geometric methods. The methodology and results provide tools when modeling CPP material as an infiltration interface, a conveyance/storage medium for liquid and gas, a filtration material for particle removal from...
