A pervious concrete infiltration basin was installed on the campus of Villanova University in August 2002. A study was undertaken to determine what contaminants, if any, were introduced to the soils underlying the site as a result of this best management practice (BMP). The average infiltration rate at the site is approximately 10 )4 cm ⁄ s. The drainage area (5,208 m 2 ) consists of grassy surfaces (36%), standard concrete ⁄ asphalt (30%), and roof surfaces (30%) that directly connect to the infiltration beds via downspouts and storm sewers. Composite samples of infiltrated stormwater were collected from the vadose zone using soil moisture suction devices. Discrete samples were collected from a port within an infiltration bed and a downspout from a roof surface. Samples from 17 storms were analyzed for pH, conductivity, and concentrations of suspended solids, dissolved solids, chloride, copper, and total nitrogen. Copper and chloride were the two constituents of concern at this site. Copper was introduced to the system from the roof, while chloride was introduced from deicing practices. Copper was not found in porewater beneath 0.3 m and the chloride was not significant enough to impact the ground water. This research indicates that with proper siting, an infiltration BMP will not adversely impact the ground water.

“…De acuerdo con la experiencia internacional, las mezclas de hormigón poroso deben ser compactadas con un rodillo pesado de ancho mayor que el de la losa a hormigonar (FCPA, 1990;GCPA, 1997;Reyes & Torres, 2002;Kwiatkowski, 2003). Por esta razón se diseñó un rodillo de 300 mm de diámetro, 600 mm de ancho y 115 kg de peso, que proporciona presiones similares a las utilizadas en terreno (0.08 MPa).…”

“…According to the international experience, pervious concrete mixtures should be compacted with a heavy roller, which width should be larger than that of the slab to be cast (FCPA, 1990;GCPA, 1997;Reyes & Torres, 2002;Kwiatkowski, 2003) Figure 3). …”

ResumenEl trabajo presentado en este estudio muestra la deducción de una ecuación que permite dosificar hormigones porosos en función de la razón agua-cemento y del porcentaje de vacíos interconectados que se requieren en el hormigón endurecido. Usando esta ecuación se analizó el comportamiento de 18 mezclas de hormigón poroso conteniendo razones agua-cemento entre 0,29 y 0,41. Las probetas fueron fabricadas en laboratorio y compactadas con rodillo pesado simulando el proceso constructivo en terreno. Los resultados permiten caracterizas de buena forma el comportamiento estructural e hidráulico de estas mezclas. Relaciones entre el porcentaje de vacíos en el hormigón endurecido y la tasa de infiltración, la resistencia a flexotracción y la densidad en estado fresco son presentadas.Palabras Clave: Hormigón poroso, pavimentos porosos, permeable, drenante, infiltración
