“…During the simulated rainfall events, the runoff volumes were measured, and the infiltration capacity was assessed, measuring the discharge time at three points of each specimen after finishing the rainfall simulations in order to establish the influence of simulated rainfall intensity on the infiltration capacity of clogged porous mixture surfaces. After finalizing the permeability tests, the specimens were cleaned by combining pressure washing and back-wash cleaning methods [38], reported as the best cleaning technique for porous mixtures [17,21,39]. The cleaning procedure consisted of applying pressure washing for 1 min over the slab surface, and applying backwash cleaning for another minute, considered to be enough according to the preliminary tests performed.…”

Permeable pavements have been used widely across the world to manage urban stormwater. The hydrological behaviour of permeable surfaces is a complex process affected by many factors, such as rainfall intensity, rainfall duration, pavement geometrical conditions, and clogging level of the permeable surface, amongst others. This laboratory study was carried out to assess the influence of clogging level and rainfall intensity on the infiltration capacity of porous mixture surfaces used in Permeable Pavement Systems (PPS). Porous Concrete (PC) and Porous Asphalt (PA) mixtures with different air void contents (15%, 20%, and 25%) were subject to different clogging scenarios by using varying sediment loads (0, 500, and 1000 g/m 2 ). Permeability experiments were carried out for each clogging scenario through a new rainfall simulator specially developed, tailored, and calibrated for the laboratory simulation of a wide range of rainfall events. Permeability measurements were taken under all different scenarios as a result of the combination of the different rainfall events (50, 100, and 150 mm/h) simulated over the specimens of porous mixtures and the sediment loads applied to them. The results showed that the PC mixtures tested perform better than the PA ones in terms of infiltration capacity, showing less potential for clogging and being more easily cleaned by the wash-off produced by the simulated rainfall events.

“…In simulations of the effect of clogging performed in the laboratory, the most common material used is sand with a known size distribution curve (Sansalone et al, 2012;Shirke and Shuler, 2009;Tan et al, 2003). The sand used as clogging material in this study is of mostly granite origin.…”

“…Permeable pavements should be inspected several times during the first months after construction and thereafter at least once a year (Shirke and Shuler, 2009). Existing surface sediments over time can be corrected by maintenance to limit the risks of clogging and pollution (Legret et al, 1996).…”

Permeable asphalt pavements have been one of the solutions used to increase the permeability of road pavements given the growing urbanization and climate change. The high porosity and permeability of surface layers with PA (porous asphalt) mixtures allows the water infiltration and, consequently, reduces superficial runoff and contributes to the recharge of underground aquifers. However, the infiltration capacity may be impaired by clogged pores with sediments. The double layer porous asphalt (DLPA) was developed to mitigate this effect. This is a key issue in the pavements' service life. Information on the clogging processes in these layers is not yet well characterized. The study was carried out using a rainfall simulator in order to generate design storm events with a known intensity and duration. The experimental methodology adopted took into account different phases of evaluation of the infiltration capacity with two clogging cycles (500 and 1000 g m-2). The DLPA infiltration capacity was evaluated in the different phases after different precipitation events (100, 200 and 300 mm h-1). The results showed that, in general, the double layer porous asphalt has the capacity to drain the water, even after clogging and with lower voids content. The infiltration capacity was partially restored when subjected to simple maintenance.

“…Several maintenance studies on permeable pavement have tested alternative ways to dislodge sediment that causes blinding, including the use of pressure washers on the surface of permeable concrete (Coughlin et al, 2012;Dougherty et al, 2011) and reverse flushing (Shirke & Shuler, 2009). Both methods seem to have potential on small scale applications, as does vacuuming using an industrial vacuum, known as a shop vac (Figure 11).…”

Great investment is made in the design and installation of stormwater control measures (SCMs). Substantial research investment, too, is made to optimise the performance of SCMs. However, once installed, SCMs often suffer from lack of maintenance or even outright neglect. Key maintenance needs for wet ponds, constructed stormwater wetlands, bioretention, infiltration practices, permeable pavement, swales, and rainwater harvesting systems are reviewed with many tasks, such as the cleaning of pre-treatment areas and the preservation of infiltration surfaces, being common maintenance themes among SCMs. Consequences of lacking maintenance are illustrated (mainly insufficient function or failure). Probable reasons for neglect include insufficient communication, unclear responsibilities, lack of knowledge, financial barriers, and decentralised measures. In future designs and research, maintenance (and lack thereof ) should be considered. Assessing the performance of SCMs conservatively and including safety factors may prevent consequences of under-maintenance; and requiring regular inspection may help to enforce sufficient maintenance.
