Estudo sobre a utilização de asfalto borracha em revestimento do tipo cauq no Maranhão

Abstract

The present study has as its main objective the analysis of rubber asphalt as an alternative over regular asphalt on construction of roads of better quality and durability. This evaluation was performed based on the comparison between both asphalts, on the study of mixtures of hot-mix asphalt concrete utilizing both materials and the proper evaluation of those materials. The usage of rubber asphalt is justified by the reutilization of old, disposed tires, decrease on pollutant emissions, and greater durability of the asphalt revetment. The methodology of the study consisted on bibliographic research and laboratory experiments, aiming to achieve the proposed objectives. This work was divided in three parts: the bibliographic research, laboratory procedures and result analysis. The results obtained from both materials were considerable, while the rubber asphalt mixture showed itself to be more resistant on Cântabro Loss tests, proving to be more durable than regular mixtures
