Abstract

This study aims to investigate the effect of the temperature in the aging of a biobinder obtained from vegetal source. In this sense, the Rolling Thin Film Oven Test test was performed according to the ASTM D2872 (2012), considering the standard test temperature (163 °C) and two others test temperatures (150 °C and 180 °C). The unaged and aged binders (Neat Asphalt Binder, AC 30/45, and the biobinder) had their rheological and chemical properties analyzed. Under the same aging conditions, it was found that the biobinder was more susceptible to aging than the neat asphalt binder (AC 30/45). Regarding the biobinder aged under different conditions, the incremental RTFOT temperature presented some beneficial aspects to high-temperature performance; however, it might compromise the performance at intermediate temperature which can be inferred from fatigue tests. Chemical results indicated that the carbonyl and sulphoxide indexes were not adequate for the analysis of the oxidation and aging of the biobinder.
