With the development of urbanization, pervious concrete has been increasingly used in urban road pavement structures. The objective of this paper was to investigate the effect of stress levels and modifier (ground tire rubber and silica fume) on the fatigue life of pervious concrete and establish the fatigue equations with different survival probabilities. In order to improve the deformability of pervious concrete without sacrificing its strength, ground tire rubber and silica fume were added into pervious concrete. Two kinds of pervious concrete, control pervious concrete and ground tire rubber and silica fume modified pervious concrete, were made in the laboratory. The pervious concrete beam specimens of 100 × 100 × 400 mm were casted, and the static flexural strength and flexural strain of the two kinds of pervious concrete were tested. The fatigue lives of two pervious concretes were tested using MTS fatigue testing machine under four different stress levels (0.85, 0.80, 0.75, and 0.70). The fatigue life was analyzed by two-parameter Weibull distribution. The parameters of Weibull distribution were determined by graphical method, maximum likelihood method and moment method. The Kolmogorov–Smirnov test was used to test the Weibull distribution and the fatigue equations under different survival probabilities were established. The results showed that ground tire rubber and silica fume modified pervious concrete had better deformability while ensuring strength compared to control pervious concrete. The addition of ground tire rubber and silica fume improved the fatigue life of pervious concrete. The two-parameter Weibull distribution was suitable to characterize the fatigue characteristics and predict the fatigue life of pervious concrete. Fatigue equations with different survival probabilities were a good guide for pervious concrete design.

“…Caso se escolha um revestimento de concreto permeável moldado no local a espessura deve possuir pelo menos 10 cm (tráfego leve), os demais devem possuir espessura mínima de 8 cm (tráfego leve). Na literatura científica encontram-se inúmeros estudos que permitem desenvolver um concreto permeável com um desempenho adequado do ponto da NBR 16416 (ACI, 2010;CARLS, 2018;CARMO;COLDEBELA, 2018;NGUYEN et al, 2014).…”

O pavimento permeável permite simultaneamente o fluxo de trafego e a retenção da água pluvial para o amortecimento das vazões de cheias em bacias hidrográficas urbanizadas. Embora seja crescente a implantação desta estrutura, poucos estudos dedicam-se a avalia-lo em obras públicas. Diante disso, objetivou-se analisar o pavimento permeável implantado nas calçadas da Rua Nereu Ramos e Alameda Rio Branco, Blumenau, Santa Catarina, bem como elaborar uma proposta alternativa o qual busca apontar melhorias técnicas ao pavimento existente. Na análise contempla-se a descrição dos pavimentos “como construído” (as built), a determinação do coeficiente de permeabilidade da camada de revestimento e o registro de manifestações patológicas surgidas após a implantação da obra. Os resultados apontaram inadequações na estrutura do pavimento como baixa capacidade de reservação de água, baixo coeficiente de permeabilidade do revestimento e defeitos do tipo “placa bailarina”. Na proposta alternativa detalhou-se um perfil genérico da estrutura e dimensionou-se hidraulicamente o seu reservatório por meio do método da “curva envelope”. Espera-se que os aspectos levantados contribuam para aprimorar novas iniciativas de implantação de pavimentos permeáveis, possibilitando que a medida desempenhe corretamente a sua função no manejo de água pluvial sustentável.

Pervious concrete is considered to be an advanced pavement material in terms of the environmental benefits arising from its basic feature-high water-permeability. This paper presents the results of experimental work that is aimed at testing technically important properties of pervious concrete prepared with three different water-to-cement ratios. The following properties of pervious concrete were tested-compressive and splitting tensile strength, unit weight at dry conditions, void content, and permeability. The mix proportions were expected to have the same volume of cement paste, and, to obtain the same 20% void content for all of the samples. The results show that changes of water-to-cement ratio from 0.35 to 0.25 caused only slight differences in strength characteristics. Arising tendency was found in the case of compressive strength and a decreasing tendency in the case of splitting tensile strength. The hydraulic conductivity ranged from 10.2 mm/s to 7.5 mm/s. The values of both the unit weight and void content were also analysed to compare the theoretical (calculated) values and real experiment results. A fairly good agreement was reached in the case of mixtures with 0.35 and 0.30 water-to-cement ratios, while minor differences were found in the case of 0.25 ratio. Finally, a very tight correlation was found between void content, hydraulic conductivity, and compressive strength.
