Análise de viabilidade econômica da utilização do asfalto de borracha de pneus no Brasil

Abstract

This work aims to explore the capacity of tire rubber asphalt as a more economical and environmentally beneficial option. It observes the problem of improperly disposing of tires in nature and analyzes the process of obtaining the asphalt binder with the addition of finely ground rubber from the tires. To carry out this study, it was necessary to observe the needs that the country faces in relation to the quality of paving, which demonstrates great demands in terms of safety and maintenance. From this, the impact that tire rubber asphalt generates on the durability and resistance of th e pavement is analyzed, in addition to other important characteristics conferred, such as greater grip and permeability. Overall, the study found that tire rubber asphalt has a higher implementation cost than conventional pavement, however, as it requires considerably less maintenance over time, the savings generated can be very beneficial for Brazilian cities, in addition to environmental gains, with the beneficial disposal of tires and the quality of roads.
