• Abstract:

  Currently, with urban sprawl, there are two major issues of concern: soil sealing and the generation of civil construction waste (RCC). Soil compaction and asphalting make it difficult for water to infiltrate, which can lead to flooding in lower areas. The waste generated, when disposed of irregularly, causes obstruction of roads, proliferation of vectors, silting of streams and rivers, etc. The use of permeable concrete pavements made with RCC aggregates is an innovative and sustainable solution to this problem. Therefore, this project proposes to incorporate recycled aggregates in the production of structural concrete, for later application in draining pavements. The research is divided into three interconnected stages, namely: 1st) characterization of natural and recycled aggregates and study and definition of permeable concrete traces, varying the proportion of gravel replacement by RCC (for execution during 2021); 2nd) preparation and characterization tests of permeable concrete developed in the previous stage (execution in 2022); and 3rd) production and application of permeable concrete blocks for use in pavements (to be carried out in 2023). The research is supported by the company Mejan Ambiental, with the supply of recycled aggregate. It is hoped, with this work, to contribute to the sustainable development of the country.
