Characterization of asphalt fume composition by GC/MS and effect of temperature

The aim of this work is to identify the volatile organic compounds (VOC) from asphalt by developing a process at atmospheric pressure under air flow in order to qualify and quantify the asphalt emissions by a standard analytical protocol with gas chromatography coupled to mass spectrometry. VOC formation depends on various parameters such as the asphalt temperature, the asphalt oxidation, and the humidity of air. This research contributes to improve knowledge of asphalt emissions. A decrease in VOC is mainly correlated with the asphalt temperature.
