The high rates of population growth since the beginning of the 20th century have been putting pressure on the environment concerning the need to exploit natural resources and generating problems of lack of urban infrastructure. In addition to the impacts caused by the densification and consumption of natural resources, another type of pollution worries big cities, noise pollution, caused mainly by vehicles. Daily pollution in urban centers directly impacts people's quality of life, with damage that can be irreversible to health. In this regard, this research evaluates the effectiveness of using box-type gabions as a form of acoustic barrier, having in its filling the use of construction waste. For the study, the initial physical conditions of the construction residues are characterized for later use. The box gabions were filled with Civil Construction Waste (RCC) and assembled with pre-established dimensions in an accurate scale laboratory at the Nove de Julho University (Vila Prudente Unit). After capturing, recording, and measuring the sound noises in places with heavy traffic in the city of São Paulo, the noises were replicated with intensities greater and equal to those collected on the roads and imposed on the barrier erected in the laboratory. In this way, this dissertation, in addition to proposing a technically viable solution for the final destination of civil construction waste, also brings the evaluation of a solution for the attenuation of noise pollution on roads with heavy traffic in cities.
