“…This property is directly related to the particle size distribution and the consumption of materials. Table 4 lists a summary of the mechanical and hydraulic properties According to Table 4, the coefficients of variation found for the properties evaluated are in accordance with the literature [31], due to the quality control during the casting of the specimens, once all concretes were cast on the same day, reducing the temperature interference. In addition, moisture control of the aggregates was performed and, because the compacting procedure was performed with the help of the vibrating table, there was a reduction in the variability resulting from the human operator in the production process.…”

ResumoThe objective of this work is to make feasible the use of FEA slag instead of the conventional bulk aggregate in the pervious concrete (PC) production, reaching the minimum parameters required by NBR16416/2015 and ACI 522R-10. This substitution would minimize the use of natural aggregates, besides taking advantage of a residue that has no specifi c destination. In order to reach the objective, three FEAs with diff erent grain sizes were chosen: 6-10 mm (A), 10-20 mm (B) and fi nally a mixture of the two previous ones (C) in the proportion 30-70 respectively. In order to evaluate its mechanical behavior, tests of compressive strength and fl exural tensile tests were carried out, while the evaluation of the hydraulic behavior, porosity and constant head permeability test were performed. The compressive strength varies from 19-31MPa and 3-4MPa for fl exural tensile strength was obtained. In hydraulic terms, the porosity varied from 15-20% and the permeability coeffi cient was 10-12mm/s. There is also a direct infl uence of grains of size less than 4.8 mm (small aggregate) on the compressive strength and permeability of PCs. At the end of the results, it was possible to establish a correlation between the compressive strength, the permeability and the percentage of grains inferior to 4.8mm (sand%), being this positive in relation to the studied variables, that is, the mechanical and hydraulics. Therefore, it has been concluded that the total substitution of conventional aggregates by FEA in CoPe manufacturing will comply with the minimum parameters of NBR 16416/2015.O objetivo deste trabalho é viabilizar o uso de escória de forno elétrico (FEA) em substituição ao agregado graúdo convencional na fabricação de concreto permeável (CoPe), atingindo os parâmetros mínimos exigidos pela norma NBR16416/2015. Esta substituição minimizaria a utilização de agregados naturais, além de aproveitar um resíduo que não tem destinação específi ca. Para alcançar o objetivo foram escolhidos três FEA's com diferentes distribuições granulométricas: 6-10 mm (A), 10-20 mm (B) e fi nalmente uma mistura das duas anteriores (C) na proporção 30-70 respectivamente. Para avaliar seu comportamento mecânico foram realizados ensaios de resistência à compressão e tração na fl exão, enquanto na avaliação do comportamento hidráulico, índice de vazios e permeabilidade à carga constante foram realizados. Na compressão foram obtidas resistências variando de 19-31MPa e 3-4MPa na tração na fl exão. Em termos hidráulicos, o índice de vazios variou de 15%-20% e o coefi ciente de permeabilidade de 10-12mm/s. Também se verifi ca a infl uência direta dos grãos de tamanho inferior a 4.8 mm (agregado miúdo) na resistência à compressão e na permeabilidade dos CoPes. Ao fi nal, a partir dos resultados obtidos foi possível estabelecer uma correlação entre a resistência à compressão, a permeabilidade e a porcentagem de grãos inferiores a 4.8mm (%areia), sendo esta positiva em relação às variáveis estudadas, ou seja, as propriedades mecânicas e hidráulica.

“…Solving the problem of clogging will make porous concrete more efficient, resilient, and cost effective, thereby promoting wider use. However, the study also found that existing maintenance methods for porous concrete, such as vacuum sweeping and pressure washing, had questionable effectiveness [40].…”

Understanding clogging mechanisms in permeable pavements can help optimize the required maintenance regime. In this review paper, methods for investigating clogging mechanisms are described. These include surface infiltration methods, the use of embedded sensors, and the development of modelling tools. Previously conducted surface infiltration tests indicate the importance of the age of a permeable pavement system and also local climatic conditions, including rainfall intensity. The results indicate that porous concrete generally has the highest infiltration capacity and this is followed by permeable interlocking concrete pavement and then porous asphalt. The measured infiltration rates decreased significantly even within two years of installation. There was an indirect relationship between surface infiltration rates and the age of the pavements. It was also found that the rainfall characteristics are important in selecting the type of pavement. Sensor technologies have been used mainly in the United States and there has been a reluctance to use such technologies in other parts of the world. Few studies have been conducted into modelling the changing performance of permeable pavement systems over time and there is a need to develop more general models. Various methods and machinery have been developed for cleaning and maintaining permeable pavements and there is no universally preferred approach currently available. Indeed, several of the commonly used maintenance methods have been shown to be relatively ineffective.

“…A comprehensive review was recently presented (Kia et al, 2017). Some studies have observed that clogging usually occurs on the surface or in the upper layer of the permeable pavement (Kayhanian et al 2012, Yong et al 2013, while others found that sediments are likely to clog within the permeable concrete or underlying soil (Chopra et al, 2010;Mata and Leming, 2012;Lucke and Beecham, 2011).…”
