Critical analysis of the Brazilian national standard for concrete permeable pavement

Abstract

The use of permeable pavement in Brazil has increased significantly in recent years, after being considered and encouraged in town Urban Drainage Masterplans and legislation. Unfortunately pathologies and poor performance are often observed. As part of sustainable urban drainage systems (SUDs) the main goal with a permeable pavement is to reduce the volume and also to increase the quality of stormwater runoff, but incorrect design and construction and/or lack of proper maintenance could lead to not meeting these goals. It then becomes necessary to develop the standards of the design, construction and maintenance of permeable pavements. In the paper the yet to be published Brazilian national standard for concrete permeable pavement is analyzed.
