ANÁLISE DA VIABILIDADE DO CONCRETO FABRICADO COM RESÍDUOS DE PAVIMENTO ASFÁLTICO

Abstract

Considering the confluence between the environment and the construction industry, concern for the preservation of the environment is becoming increasingly present at construction sites, which justifies the great interest in research aimed at sustainability in civil construction. With this, the current study seeks to analyze the behavior of concrete from the incorporation of asphalt paving waste. Such waste is produced on a large scale through the need to excavate paved streets and roads, which come from maintenance of asphalt paving or even carrying out infrastructure works. From the collection of this material, the asphalt pavement blocks were crushed into a more granular material, which, after being sieved, was used in the composition of the concrete, replacing the coarse aggregate. Workability and resistance to axial compression were evaluated, and these tests were carried out in the construction materials laboratory of Faculdade de Inhumas - FacMais, based on ABNT standards. It was attested that with the increase in the concentration of asphalt residue in the mass, there was a decrease in the workability and consequently the resistance of the concrete. However, this replacement becomes viable in the production of concrete artifacts that do not require great resistance, considering that there will be an ecological benefit with the reuse of asphalt material, in addition to reducing the search for raw material from the crushing of rocks, a method that causes lasting damage to natural resources.
