“…The static and dynamic loads produced by the vehicle wheels can produce permanent deformations in the pervious surface, which could affect both porosity and permeability. Moreover, the vehicle wheels are the main source of particulate matter that can clog the pervious surfaces, especially due to the compaction force produced by the vehicle loads, this effect being more important in the contact zone between wheel and surface [14,15].…”

Porous surfaces have been used all over the world in source control techniques to minimize flooding problems in car parks. Several studies highlighted the reduction in the infiltration capacity of porous mixture surfaces after several years of use. Therefore, it is necessary to design and develop a new methodology to quantify this reduction and to identify the hypothetical differences in permeability between zones within the same car park bay due to the influence of static loads in the parked vehicles. With this aim, nine different zones were selected in order to check this hypothesis (four points under the wheels of a standard vehicle and five points between wheels). This article presents the infiltration capacity reduction results, using the LCS permeameter, of Polymer-Modified Porous Concrete (9 bays) and Porous Asphalt (9 bays) surfaces in the University of Cantabria Campus parking area (Spain) 5 years after their construction. Statistical analysis methodology was proposed for assessing the results. Significant differences were observed in permeability and reduction in infiltration capacity in the case of porous concrete surfaces, while no differences were found for porous asphalt depending on the measurement zone.

“…[3] As shown in the example of VD4 in Figure 4 using neutron images the complex configuration of water in a coarsely porous material could be captured, in addition to filled pores, water films or wet surfaces, partially filled deadend pores and water islands standing in the pore system could be seen, thus disconnected from other filled pores. After a rain event, the PA undergoes first drainage driven by gravity.…”

“…Al-Omari et al [27] were the first to prove the correlation between the permeability estimated based on CT images and the laboratory tests. Gruber et al [28] made similar research, they examined the void structure and permeability of porous asphalts by superimposing the numeric simulation of flow over the three-dimensional microstructure. The research showed that there was no correlation between permeability and porosity, and flow inside the void structure is strongly anisotropic.…”
