Water pervious concrete pavement blocks: durable structures for an integrated water policy

Water pervious pavement blocks are a durable and ecological solution to prevent water run off, to minimize the risk of flooding and to increase the efficiency of water purification. The application of water pervious pavement blocks on a permeable base and/or sub base allows buffering of the rainwater in the structure and infiltration or retarded outflow to the ground or infiltration system. This paper presents the results of a research project, conducted at the Belgian Road Research Center (BRRC) during 4 years. The efficiency of water buffering and infiltration in relation to the choice of material is investigated in the laboratory, on a test parking lot and on site. To allow a good choice of the materials and the application site and to control the efficiency on site, different test methods are optimized. Results for different types of concrete pavement blocks (pervious blocks, blocks with enlarged joints or drainage holes), different types of base layer (hydraulic bounded or unbounded materials) and different types of sand layer and jointing materials are looked at. Finally this paper focuses on several applications in Belgium, where measurements have shown a good behavior of the structure and a good durability of the permeability. Data from newly constructed projects, as well as projects in use for more than eight years are presented.
