Resumo
De acordo com o ex-presidente Washington Luis (1920), “Governar é Povoar”. A política de expansão da malha rodoviária, mais conhecida como rodoviarismo, o teve como precursor. Entretanto, foi por volta de 1950, com o ex-presidente Juscelino Kubitschek, que esse movimento expandiu de forma abrupta, caracterizando no Brasil, o modal rodoviário como predominante até os dias atuais.
Com isso, diversas problemáticas surgiram ao longo dos anos, principalmente de cunho sustentável. Afim de solucioná-las, o incentivo ao estudo de tecnologias alternativas nos quais visam a diminuição dos impactos de determinados processos e materiais ao meio ambiente, tornaram-se indispensáveis e crescentes.
A aplicação do asfalta-borracha, em substituição ao CAP convencional, tem se demonstrado extremamente promissor. No âmbito da utilização de materiais derivados do petróleo, a reutilização de pneus inservíveis, vem melhorando o desempenho, aumentando a rigidez a elevadas temperaturas, reduzindo as deformações permanentes, aumentando a flexibilidade e retardando o aparecimento de trincas.
Através dessa revisão bibliográfica, abordaremos essa que é uma tecnologia assertiva em diversos fatores, provando que apesar do custo levemente maior, segundo o Departamento Nacional de Infraestrutura de Transportes - DNIT, os bônus superam os ônus.
According to former president Washington Luis (1920), “Governing is People”. The policy of expanding the road network, better known as highways, had him as a precursor. However, it was around 1950, with the ex-president Juscelino Kubitschek, that this movement expanded abruptly, characterizing in Brazil, the road modal as predominant until the present day. As a result, several problems have arisen over the years, mainly of a sustainable nature. In order to solve them, the incentive to study alternative technologies in which they aim to reduce the impacts of certain processes and materials on the environment, have become indispensable and growing. The application of asphalt-rubber, replacing conventional CAP, has shown to be extremely promising. In the context of the use of materials derived from petroleum, the reuse of waste tires has been improving performance, increasing stiffness at high temperatures, reducing permanent deformation, increasing flexibility and delaying the appearance of cracks. Through this literature review, we will approach this technology that is assertive in several factors, proving that despite the slightly higher cost, according to the National Department of Transport Infrastructure - DNIT, the bonuses outweigh the burdens.
