AGREGADOS RECICLADOS DE CONCRETO DA USINA DE RCC DE RIO VERDE/GO: CARACTERIZAÇÃO E VERIFICAÇÃO NORMATIVA PARA FINS DE PAVIMENTAÇÃO

Abstract

Civil construction is one of the sectors that most cause environmental impacts in the world and also one of the largest waste producers, and the municipality of Rio Verde produces a daily average of approximately 188t of civil construction waste (CW), so this work shows an alternative for the reuse and improvement of waste produced by the construction industry through a fixed recycling plant installed in the municipality of Rio Verde - GO, and waste from construction and demolition is transformed into aggregates, which can be used in pavement layers (base, subbase, subgrade reinforcement or primer coating). In this sense, the possibility of using CW in the form of RCA for this paving purpose was evaluated, technically evaluating the RCA use in granular layers of pavement, through physical and mechanical characterization of the materials processed in the recycling plant of Rio Verde. So that the materials showed acceptable technical characteristics by the standards of GOINFRA ES - PAV 005/2019, DER-ET-DE-P00/013 and NBR 15115- 2004 through the tests carried out for RCA physical and mechanical characterization.
