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.
