Pervious Concrete in Severe Exposures

Porous pavement, especially portland cement pervious concrete (PCPC), helps control pollution discharge by allowing rainwater to rapidly infiltrate into an open-graded aggregate subbase and into the ground. Hydrocarbons become attached to the large surface area of the PCPC or the aggregate subbase and are reduced by natural attenuation, either through evaporation or biological degradation. PCPC also mechanically filters out larger pieces of metal or biological material for later collection during routine maintenance. Thus, the majority of first-flush pollutants are removed by the pervious concrete system, preventing the pollutants from entering stormwater collectors and being conveyed to local surface waters. By allowing stormwater to naturally percolate into the soil, PCPC can also reduce or eliminate the need for stormwater retention areas and the infrastructure required to convey the water. This article provides a summary of the authors' work in this area that focused on the durability of PCPC subjected to freeze/thaw cycles.
