| Resumen en inglés | The use of pervious concrete as a way to improve urban drainage problems have been spread in Brazil. In this context, this paper compared two concrete pavements, one conventional and other pervious, using the Life Cycle Assessment (LCA) approach. Primary data was collected from a concrete plant in the region and a case study was used in the parking lot of the Estádio Nacional de Brasília, considering the stages of production, transportation and maintenance of pavements throughout their life cycle. Two functional units were adopted, one of them considering the drainage effects provided by the pervious pavement. In the first functional unit (in m³ of concrete produced), the pervious concrete pavement presented greater environmental impacts than the conventional concrete pavement, mainly due to its higher consumption of cement and its shorter useful life. However, it was observed that when the drainage effect is considered, in terms of the functional unit, the results show that the pervious pavement presents a better environmental performance for all environmental impact categories evaluated. In conclusion, it can been seen the importance of the choice of a functional unit that represents the performance of the materials evaluated in a LCA study |
| Resumen en portugués | A utilização de pavimentos drenantes como forma de melhorar problemas referentes a drenagem urbana tem se difundido no Brasil. Neste contexto, o presente estudo comparou dois pavimentos de concreto, um convencional e outro drenante, utilizando a metodologia de Avaliação do Ciclo de Vida (ACV). Foram coletados dados primários de uma usina de concreto da região do Distrito Federal e utilizado como estudo de caso o estacionamento do Estádio Nacional de Brasília, considerando as etapas de produção, transporte e manutenção dos pavimentos ao longo de seu ciclo de vida. Foram adotadas duas unidades funcionais, sendo que uma considerou os ef |
