Abstract


The present research shows the results of an equation that allows to dose pervious concrete in function of water to cement ratio and the required interconnected void content in hardened concrete. Eighteen different mixtures - with w/c ratio between 0.29 and 0.41- were analyzed using this equation. The samples were made in the laboratory and compacted with a heavy roller simulating site conditions. The results allow a good characterization of these mixtures both mechanical and hydraulic behavior. Reliationships between void contents, infiltration rate and flexural strength were found.
