Reutilização da borracha de pneus descartados para uma melhor resistência e vida útil do asfalto

Abstract

Brazil's largest cargo transportation modal, the highway system suffers from low growth of its network and expensive and inefficient maintenance of existing roads. The final consumer is the one who pays for this and has the cost of the products added to the difficulties of the transporters. Pointed out in several studies as a possible solution to these problems, the mixture of reused tire rubber dust with bituminous concrete is capable of improving the durability of sidewalks and also brings ecological benefits. This article aims to analyze improvements with the use of asphalt-rubber in order to encourage the public administration and companies that have highway concessions to use it. The methodology used for this was bibliographic and documentary research in websites, research institutes and academic papers. The conclusion reached was that rubber asphalt is advantageous: despite its higher initial cost, road improvement brings benefits to users, to the final consumers of the products, to the environment, and even to public health.
