Effect of Age of Permeable Pavements on Their Infiltration Function

Abstract

This study describes field investigations designed to compare the infiltration capacities of 55 permeable pavement systems installed in the Netherlands and in Australia. The ages of the pavements varied from 1 to 12 years. Using infiltrometer testing, the performance of the pavements has been compared in terms of their ability to infiltrate a three month average recurrence interval storm event in the case of the Australian pavements or the minimum specification for European infiltration capacities of 97.2 mm/h for the Dutch pavements. Many of the tested pavements broadly follow a hypothetical decay curve of infiltration rate with age of pavement. However, these are clustered into two distinct groups (Dutch and Australian) with the older Australian pavements appearing to maintain higher infiltration rates relative to their age. The study has shown that the performance of the clogged permeable pavement systems was still generally acceptable, even after many years in service.

Hydraulic Performance of Lined Permeable Pavement Systems in the Built Environment

“…Due to a number of malfunctions related to local power outage, software problems and defective instruments, we report a continuous monitoring period of 12 months starting from 1 December 2014, i.e., to a starting point 19 months after completion of installation, thus initial high surface permeability rates were assumed to have settled to a more permanent level [9,22,23], providing results representative of a longer period of functional lifetime. The stalls were enrolled in the present maintenance program for surrounding conventional pavements, which includes occasional collection of litter and debris, but no specific actions to maintain high surface permeability.…”

Spatial and temporal variability of rainfall and their effects on hydrological response in urban areas – a review

“…The presence of leakage from drinking water and sewer networks can increase infiltration to groundwater and amount of contaminants that is spread from the sewer system into the soil (Salvadore et al, 2015). Although it is well known that not all rainfall turns into runoff (Boogaard et al, 2013;Lucke et al, 2014), it is common to consider the losses from impervious areas so small that they can be assumed negligible compared to the total runoff volume (Ragab et al, 2003;Ramier et al, 2011). Ragab et al (2003) tried to emphasize the importance of ac-counting for infiltration in the urban water balance, and found that infiltration through the road surface can constitute between 6 and 9 % of annual rainfall.…”

“…Ragab et al (2003) tried to emphasize the importance of ac-counting for infiltration in the urban water balance, and found that infiltration through the road surface can constitute between 6 and 9 % of annual rainfall. Due to high spatial variability of infiltration, representative measurements are difficult to obtain and require a large amount of point-scale measurements (Boogaard et al, 2013;Lucke et al, 2014).…”

“…Monolithic structures consist of a combination of impermeable blocks of concrete and open joints or apertures that allow water to infiltrate. In modular structures, gaps between two blocks are not filled with sand, as with conventional pavements, but with 2-5 mm of bedding aggregate, that facilitate infiltration (Boogaard et al, 2013) Wegenbouw, 2008).…”

A Simple Field Test to Evaluate the Maintenance Requirements of Permeable Interlocking Concrete Pavements

“…However, this process has also been shown to reduce the hydraulic performance of PICPs over time due to clogging [1,2,7]. Although infiltration rates of newly installed pavements have been shown to be high [9][10][11] these rates are known to diminish over time due to clogging, potentially leading to a decrease in useful lifespan, more maintenance and higher replacement costs [12,13]. Accelerated surface clogging can lead to more frequent maintenance intervals and increased costs.…”
