“…For this reason, a polyurethane-bound pervious mixture (PUPM) was developed by using the polyurethane (PU) to replace bitumen as the binder. Numerous researches have verified that PUPM has the notable mechanical and functional performance to be realized [14][15][16][17]. Moreover, during construction, PU can be cured at room temperature.…”

Permeable pavements are often affected by pore clogging, which leads to their functional failure and reduced service life. However, the clogging mechanism and its impact on the permeability and complex pore microstructures in pervious pavement remain unclear. The aim of current study is to quantify the clogging behavior in pervious pavement materials and carry out investigations on the development of pore characteristics and permeability. Novel polyurethane-bound pervious mixture (PUPM) was adopted for comparative study in present research with conventional Porous Asphalt (PA). The Aachen Polishing Machine (APM) was selected to perfectly serve as a simulator for clogging process of pavement in the actual service condition. The permeability and pore microstructure of the pervious pavement material were then characterized by using the self-developed permeameter and X-ray Computed Tomography (CT) scanning, respectively. The development of pore characteristics in terms of clogging was experimentally illustrated. Based on the pore characteristics, the flow behavior of PUPM subjected to different clogging periods was predicted based on the developed non-Darcy flow model. The developed experiments and analysis can further strengthen the understanding of the clogging mechanism within the porous pavement material. The results can also serve for the optimization of the pervious pavement design in the engineering application.

“…Permeable pavements are an alternative solution for impermeable surfaces used in residential, commercial, and industrial areas, for parking, roads, or pedestrian paths, especially where the traffic is low (Sanicola et al 2018;Sun et al 2018). This is an effective way to improve hydrological and ecological properties in urban areas (Sanicola et al 2018;Lu et al 2020). Permeable pavements have been reported to perform four hydrological functions: storage of rainwater, reduction of surface runoff, outflow delay, and the delay of peak outflow (Fassman and Blackbourn 2010;Lin et al 2014).…”

“…Permeable pavements can consist of various materials, characterised by high porosity and a void-rich structure so that rainwater can freely infiltrate through the layers. According to the literature, the most suitable materials include porous asphalt, porous cement, permeable interlocking concrete pavement, or advanced polyurethane mixtures (Sun et al 2018;Lu et al 2020).…”

Blue-green infrastructures (BGI) integrate solutions implemented to enhance water management and landscape values for more climateresilient and livable cities. BGI have created an opportunity to renew the natural structure of water balance in cities through the increase in rainwater retention and enlargement of permeable areas. The review of the literature on BGI development and solutions showed that the most popular BGI elements in terms of urban water quantity and quality were rain gardens, green roofs, vertical greening systems, and permeable pavements. Their structure and effectiveness were presented and reviewed. Despite the consensus between researchers that BGI benefit urban hydrology, differences in runoff decreased (2%-100%) lowering the peak flows (7%-70%) and infiltration (to 60%) or evapotranspiration (19%-84%) were reported. Due to an individual technical structure, each BGI element plays a specific role and there is no universal BGI solution against water-related problems. We inferred that the most effective ones were individually adapted solutions, which prevent from a stressor. The greater variety of solutions in a given area, the more benefits for the urban environment. Our analyses showed that a holistic and co-creative approach to create blue-green networks should be considered in modern water management plans.

“…When measuring the water level in the road construction and the surface moduli measured for each water level, the E-moduli can be expressed according to variations in water levels [61]. This is similar work to the study [62] that focuses on the pore pressure of materials in a permeable pavement in a field test that is under traffic loading.…”

This paper is a literature review focused on permeable pavements and especially the permeable subbase material. Run-off water from the surface is traditionally let through a drainage system, and the roads are kept dry. Due to climate changes, heavy precipitation and high-intensity rainfalls are putting pressure on the infrastructure. Traditionally, water in subbase materials reduces the resilient E-moduli and the lifespan of the pavement design. Studies show that increasing saturation reduces the bearing capacity of a traditional subbase material. Unbound materials with highly grained fines and high moisture content have higher tendency to show reduced resilient E-moduli. One study was found where the E-moduli of five different coarse grained aggregates used in permeable pavements were examined through a triaxial test. It was found that the E-moduli varied from 110–371 MPa. Other studies examining the E-moduli of permeable subbases based on moisture content were not found. However, this paper discusses different experiences regarding the bearing capacity of traditional vs. permeable subbase materials. It also covers a discussion and an analysis of missing research areas that needs to be investigated for further knowledge about the usage of permeable pavements in areas with a risk of flooding.
