Abstract:
Impervious surfaces, such as roads, parking lots, roofs and sidewalks, play a crucial role in the urban expansion and infrastructure of modern cities. However, its indiscriminate increase contributes to the sealing of the soil, resulting in significant drainage problems and increased surface runoff during rain events. Removing vegetation and replacing it with impermeable pavement alters the natural balance of the soil, compromising its ability to absorb water. This, in turn, intensifies the risks of flooding, soil erosion and environmental degradation. Given this scenario, the search for alternative soil coverings that can minimize such impacts becomes imperative. Porous or draining pavements have permeability indices, while interlocking pavements and grassy pavements are evaluated in terms of percentage of water absorption. These characteristics reflect the ability of these different types of pavements to deal with water infiltration, contributing to the adequate management of rainwater runoff in urban environments. To evaluate the technical feasibility of drainage pavements, a comparative study of permeability, water absorption and void index, was carried out between drainage concrete and polymeric permeable pavement developed in the laboratory.
