Clogging and maintenance evaluation of pervious concrete pavements with recycled concrete aggregate

Are Permeable Pavements a Sustainable Solution? A Qualitative Study of the Usage of Permeable Pavements

“…This was discussed in Section 4.2 as one of the problems, which is also mentioned in several studies [4,7,14,34]. Some of the clients were worried as they are experiencing issues with the top layer as the construction of the pavement is finished, and as the study [33] states for concrete porous surface top layers, it is necessary to perform periodic cleaning to obtain the best results. However, this does not solve the specific problem based on these interview, where the problem is not water management directly, but the appearance and condition of the pavement a couple of years after the construction phase has concluded.…”

“…The clogging in the surface is especially observed in pavements with porous asphalt, where there air voids are clogged with dirt. According to [4], permeable pavements needs maintenance at least twice a year to be able to hold up its infiltration rate, and according to study [33], which was conducted on porous concrete, it was concluded that periodic cleaning is necessary to maximize the life of the surface. In principle, this type of clogging is natural and thus also problematic to avoid.…”

A Review of Porous Concrete Pavement: Compressive Strength and Clogging Investigation

“…Pervious concrete pavements (PCPs) are used more frequently because of their environmentally beneficial properties. In addition, PCPs are a permeable pavement system that allows surface water to infiltrate the ground and reduce the impact of the urban heat island effect [1][2][3][4][5][6][7]. Various environmental advantages are attributed to PCPs, including improved runoff and infiltration of stormwater, improved skid resistance of pavement surface, improved subsurface water quality, decreased hydroplaning, heat-island effect, and traffic noise [8].…”

“…The material's compressive strength is only about 20-30 MPa. Furthermore, the sediment and debris accumulated on the pavement's surface will create a clogging problem [5]. This accumulation reduces surface infiltration rates, eventually leading to surface ponding.…”
