RESUMO

The present work intents to show design and built procedures, of porous pavements; by paying attention on its practical appliances as compensatory option in urban drainage with purpose to retaining rainfall water by storage, reducing downstream flooding in cities with great urban density. The procedures here proposed are based in the know how acquired for the construction of two kinds of porous pavements: one built with interlocked concrete blocks and the other built with porous asphalt. In order to aid the present work, an experimental field was built as parking area inside the propriety of CTH Centro Tecnologico de Hidraulica in State University of Sao Paulo where the tests and experiments were made. The parking area is a reservoir structure where rain water is stored inside courses of aggregates. The storage volume is in the void space between particles of material that comes by infiltration trough the pavement layer. The commendation, after the studies, is that procedures and activities of design and build of porous pavements could be observed by government and private sector as alternative solution in many kinds of urban projects such as large public and private lots, parking areas sport fields side walks and streets, with low capacity of traffic loads, and so forth.
