abstract = {Permeable pavements are a well-established green solution for mitigating urban runoff, but their implementation in cities has been limited due to their low load-bearing capacity. Previous studies of a new polyurethane-based mixture, named Polyurethane Bound Permeable Mixture (PBPM), reported good resistance to heavy loads such buses and trucks. Nevertheless, PBPM remains susceptible to clogging caused by sediment accumulation transported by runoff. Consequently, this study investigated three mixtures under various clogging conditions: two PBPM mixtures with aggregate sizes of 8 mm (PBPM8) and 5 mm (PBPM5), and one bitumen-based mixture with an aggregate size of 8 mm (PA8) as control. Laboratory experiments were conducted using a rainfall simulator and real sediments to evaluate the impact of sediment particle size, sediment load, and rainfall intensity on the hydraulic conductivity (Kv). Three experiments were conducted: Experiment 1 determined the combination of rain intensity and sediment particle size distribution (PSD) that caused maximum clogging; Experiment 2 assessed Kv reduction with increasing sediment loads (applied in multiple steps) at a fixed rainfall intensity; and Experiment 3 examined Kv changes under different combinations of sediment loads (applied in one step) and rainfall intensities. PBPM exhibited superior clogging resistance, maintaining ∼40% of its initial Kv at 2000 g/m², outperforming PA8 and other bitumen-based mixtures. Clogging was exacerbated by shorter rains and specific sediment size distributions, whereas lower-intensity rainfall yielded inconsistent effects. Overall, Kv decreased proportionally with increasing sediment loads. These findings demonstrate that clogging severity is governed by rainfall characteristics (duration and intensity) and sediment properties (size, load, and application method); however, comparisons with previous research suggest that porosity is a greater influence than aggregate size. This study provides a framework for developing representative laboratory-scale clogging protocols and optimizing permeable pavement mixture designs.},

abstract = {Sustainable urban drainage systems (SUDS) are common solution to address flow discharges, runoff volumes and pollutant concentrations caused by urban expansion and climate change trend. Among them, permeable pavements (PP) effectively manage and treat stormwater. The clogging process of PP has been addressed in previous studies but there is still room for improvement the knowledge about how it affects to their performance in terms of hydrological behaviour and pollutant removal and how it depends on sediment properties. The present study simulates and analyses the behaviour of a permeable asphalt through 47 sediment loading steps tested for six different sediment classes under laboratory conditions. The experiments were performed using permeable asphalt slabs in two laboratory rainfall simulators, measuring reductions in permeability, filtered and runoff flows, and water quality variations in effluents according to sediment loads and rainfall events. The results showed significant reductions of permeability (22–99 %) for sediment surface loads from 1 kg/m2 onwards, except for very fine sediments (<125 μm) (1 %). Permeability recovery after vacuum cleaning varied between 8 % and 100 % of original permeability. Sediment particle size distribution, organic matter content and rain events sequence were key variables influencing the permeability loss and its recovery, and quality of filtrated water. The hydraulic efficiency was high, filtrating almost 100 % of the applied rainfall, whenever the sediment surface load was below 4 kg/m2, above which surface runoff was produced. The efficiency of the slab for pollutant retention was 96 % for COD, 76 % for TN, 79 % for TP, and 98 % for TSS.},

abstract = {Sustainable urban drainage systems (SUDS) were almost unknown in Spain two decades ago; today, urban drainage in the country is transitioning towards a more sustainable and regenerative management in a global context where green policies are gaining prominence. This research establishes a diagnosis of SUDS in Spain and examines the extent to which the country is moving towards the new paradigm in three dimensions: (a) the governance and social perception of the community, (b) the regulative background, and (c) the implementation and the technical performance of SUDS. The diagnosis identifies barriers that hinder the change. Then, we define the challenges that Spain has to face to overcome obstacles that delay the transition. Barriers to the governance sphere are related to the lack of involvement, knowledge, and organisational responsibilities. Within the regulative framework, the absence of national standards hinders the general implementation at the national scale, although few regional and local authorities are taking steps in the right direction with their own regulations. From the technical perspective, SUDS performance within the Spanish context was determined, although some shortcomings are still to be investigated. Despite the slowdown caused by the hard recession periods and the more recent political instability, SUDS implementation in Spain is today a fact, and the country is close to reaching the stabilisation stage.},
