Análise da Viabilidade Técnica da Reutilização de Material Fresado Proveniente da BR-135

Abstract

The objective in this conducted research is to approach the reuse viability of the material income pavement milling from the road BR-135. The analysis was conducted with asphalt mixtures and it is a technique used in paving, the recycling. The study’s goal is to evaluate if the milled material from the BR-135 can be reused as a construction material of new roads. To start the analysis, it was obtained necessary materials and, these were verified through laboratory tests if they can be reused as an asphalt mixture based on the DNIT 033/2005 – ES and DNIT 034/2005 – ES regulations (Brazilian regulations about hot recycled mixtures). After the tests, two mixtures were defined to be analyzed and the proportion of each material that constitute them. Then, test specimens were molded with a Petroleum Asphalt Cement (PAC) percentage from 2.5% to 4.5% and they were tested to determine their characteristics. From the results, new test specimens were molded using an ideal binder (percentage of project) and these were analyzed again. The acquired results to the proposed recycled asphalt mixture, in accordance with the recycling regulations, were unsatisfactory
