USE OF RECYCLED MATERIALS IN PERMEABLE PAVEMENTS: SUSTAINABLE ADVANCES FOR URBAN INFRASTRUCTURE

Resumo

Rapid urbanization and environmental concerns related to soil impermeabilization have driven the development of sustainable solutions for urban infrastructure, such as permeable pavements. The use of recycled materials, such as recycled concrete aggregate (RCA), crushed bricks (CB), and reclaimed asphalt pavement (RAP), has proven to be a promising alternative for pavement construction, aligning with the concept of sponge cities. Recent studies show that, when properly treated and incorporated into different structural layers, these materials can provide effective solutions for rainwater management, reduce surface runoff, and contribute to aquifer recharge. In addition to contributing to urban sustainability, the use of CDW also promotes the circular economy by reducing dependence on natural resources and lowering carbon emissions. Research by Lei et al. (2020), Cai et al. (2020), and other studies show that using treatments such as silicone resin and lime, along with strict quality control of recycled materials, can improve the mechanical properties and water stability of pavements. Despite challenges like clogging and abrasion, the analyses indicate that these solutions are viable for both urban and rural pavements. The large-scale implementation of permeable pavements with recycled materials represents an innovative solution to urban drainage issues and construction waste management.
