Interferência da adição de óleo de canola na temperatura de compactação e usinagem de misturas asfálticas.

Abstract

Since national cargo transportation is highly dependent on the road network and the vast majority are in poor condition, there is a need for technologies that improve the quality and cost of asphalt mixtures for their application and maintenance, coupled with this reduction of pollutants and energy expenditure during the compaction and machining process. Within this study, the warm asphalt mixtures (MAMs) that are characterized by having a manufacturing temperature between 105 and 135 ° C and have been gaining prominence in the scenario of asphalt mixtures being the subject of study. This research work focuses on adding the content of 1% of canola oil to pure CAP and its effects on compaction temperatures and machining lower than that found by the rotational viscosity test (reduction of 10 ° C and 20 ° C) . Applying the methodology of characterization of aggregates, CAP and mixture of pure CAP with 1% of canola oil. From the results, it was possible to conclude that canola oil becomes promising as an additive for warm asphalt mixtures to reduce the temperature of compaction and machining, keeping its properties within the limits established by the competent bodies. It can be said that adding oil directly reduces energy costs in its production and the pollutant effects on the environment.
