Method for building roads and parking zones with a permeable base and resulting product

摘要

The invention relates to a method for building roads and parking zones enabling passage and filtration of water and having absorption wells helping the water penetrate into the subsoil. The method comprises the following steps: 1) cleaning and removing grass and trash using conventional tools; 2) compacting the soil manually or mechanically; 3) placing enclosure means, frames or permeable concrete walls with a filling; 4) placing an aggregates filling excluding dust and powder type particles; 5) casting a permeable concrete slab; 6) vibrocompacting the permeable concrete flagstone; 7) placing an asphalt or permeable vibrocompacted concrete carpet. All these elements rest on a hard aggregate filling having no dusts or sands and a permeable concrete flagstone to distribute loads.
