“…The use of a filter course can provide exceptional lag times, often in excess of 1,000 minutes or more as reported (Roseen et al 2012). The lengthening of lag time and residence time within the pavement system provides two important distinct hydrologic benefits, including greater peak reduction and groundwater recharge volumes.…”

“…Studies at the University of New Hampshire Stormwater Center (UNHSC) and in northern Europe have shown that surface infiltration rates are maintained despite a frozen subsurface. This is due to the open-graded materials and a reduced duration of frost within porous asphalt (Roseen et al 2012).…”

“…This results in extensive road deicing, with approximately 27 tons of salt applied per mile of road annually (Patten, 2011). Although reducing winter salt application by 64 to 77% is advised on porous pavement installations, this goal is difficult to achieve where porous materials receive runoff from large contributing areas of impervious surfaces that require deicing salts (Roseen, Ballestero, Houle, Heath, & Houle, 2014).…”

Engineered porous media are commonly used in low impact development (LID) structures to mitigate excess stormwater in urban environments. Differences in infiltrability of these LID systems arise from the wide variety of materials used to create porous surfaces and subsequent maintenance, debris loading, and physical damage. In this study, infiltration capacity of six common materials was tested by multiple replicate experiments with automated mini-disk infiltrometers. The tested materials included porous asphalt, porous concrete, porous brick pavers, flexible porous pavement, engineered soils, and native soils. Porous asphalt, large porous brick pavers, and curb cutout rain gardens showed the greatest infiltration rates. Most engineered porous pavements and soils performed better than the native silt loam soils. Infiltration performance was found to be related more to site design and environmental factors than material choice. Sediment trap zones in both pavements and engineered soil rain gardens were found to be beneficial to the whole site performance. Winter chloride application had a large negative impact on poured in place concrete, making it a poor choice for heavily salted areas.

“…Previous studies have assessed the stormwater quality and hydraulic performance of PA surface/system in terms of metallic pollutant removal capability and surface infiltration capacity [13][14][15][16][17][18]. Stotz and Krauth [13] and Eck et al [14] found that the total Pb concentration in the runoff from highway with the PA surface was 56∼96% lower than that discharging from traditional highway with the impermeable surface.…”

In this study, one type of porous asphalt (PA) mixture was designed at two different air void (AV) contents. Direct information regarding both the dimensional properties and AV distribution within two PA specimens in their natural states were observed, compared, and analyzed based on the X-ray CT (computed tomography) and digital image analysis techniques and fractal geometry theory. The characteristics of AV distribution, including AV content, AV number, and AV volume were quantified by comparing pore structure at different specimen heights. The dimensional properties of voids at different specimen heights were characterized by parameters in terms of equivalent diameter, specific surface area, and fractal dimension. The Pb(II) removal performance of the two PA mixtures was examined by an artificial rainfall event. The relationship between the PA microstructure and Pb(II) removal rate was then determined. It is observed from this study that the overall distribution pattern of AV inside PA specimen is independent of AV content. The distributional parameters including AV content, AV number, and AV volume show good correlations with three dimensional parameters, respectively. The Pb(II) removal in general appears to be independent of AV content because both PA mixtures have the same level of performance in removing Pb(II) during the rainfall period. The removal rate of Pb(II) shows good correlation with AV content, AV number, AV volume, and equivalent diameter of AV, indicating that a perfect distribution of AV within PA mixture is more important than the complex geometries of voids for getting a higher Pb(II) removal during rainfall event and without providing a temporary storage of stormwater in PA mixture. These findings provide an effective evidence to reveal that the AV distribution and properties characteristics have significant implications for pollutant removal in field PA pavement system.
