“…The compaction procedure used by passing the roller 15 times per layer also contributed to the high apparent density of these pervious concretes. This confirms the importance of the compacting energy on the mechanical properties and the permeability of pervious concretes [21][22][23]27]. Fig.…”

The urbanization process of the urban centers in the Amazon occurred quickly and without planning. Belém, one of the main cities in the region, suffers from intense flooding due to urbanization growth and the disorderly occupation of floodplains. The objective was to evaluate the producing of pervious concrete that meets the mechanical and hydraulic performance criteria for permeable pavement molded on site and to simulate the replacement of the entire public walkway system of a hydrographic basin in Belém in order to verify if this measure would alter the permeability of the basin and meet minimum requirements of at least 25% permeable area. The properties of three mixtures of pervious concrete with aggregates of different grading were evaluated. The permeability and flexural strength of all blends were higher than the minimum required for use as a permeable pavement for light vehicle traffic. The simulation showed that replacement of the public walkway by permeable pavement increased the permeable area of the watershed from 19 to 23%, changing from a poor condition to an acceptable level. The results indicate the potential to improve the performance of drainage systems through the wider use of permeable pavement associated with traditional structural measures.

“…The apparent density of the mixtures ranged from 2,102 to 2,264 kg/m 3 , which is considered high for pervious concretes since the vast majority of the research found in the literature has pervious concrete densities lower than 2,000 kg/m 3 [20][21][22][23][24][25][26].…”

“…While PA mixtures were produced by using a mix of 80%/20% of limestone and basaltic aggregate, respectively. PC mixtures were made with coarse limestone aggregates and 5% fine sand by weight of aggregates, according to previous works [27,28]. PA mixtures were produced with a dosage of 4% by weight of a mixture of Styrene Butadiene Styrene-modified bitumen.…”

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.

“…Next steps will be the addition of additives, starting with an extended review of the literature. The main additives and additions used in PC mixtures are being located, as well as the optimal amount used by the authors to achieve the highest mechanical results as possible [13,29,30]. In addition, it is being evaluated the use of polymers to substitute the cement, obtaining a more environmental and strong mixture.…”

Many cities around the world are handling many problems derived from urbanization, resulting in an uncontrolled growth of cities. Moreover, Climate Change effects are affecting all countries and specially cities. In this context, urban drainage and paving strategies demand a bigger economical investment to avoid a great impact in citizens quality of life, and in the environment. The main objective of this research is to contribute, in an innovative way, with the construction of concrete urban pavements by studying, quantifying and trying to join together a series of characteristics and benefits that are analyzed nowadays, but in a separately way. Trying to achieve an integrated pavement, with resilient properties (adapted to Climate Change) and more sustainable (economically, socially and environmentally).
