不同沥青排放的挥发性有机化合物（VOC）不仅会导致沥青性能的变化，还会导致其化学成分的变化。本文通过四组分分析，研究不同条件下不同沥青VOC排放对沥青化学成分的影响。结果表明，不同产地的沥青四组分存在差异。并且随着VOC排放时间的增加，树脂和沥青质的总含量增加，而饱和烃和芳烃的总含量减少。不同温度下的VOC排放量对沥青化学成分也有很大影响；高温时饱和烃和芳烃的减少量比低温时大，且沥青表层和内部化学成分存在较大差异。
Volatile organic compounds (VOC) emission from different asphalts not only causes the change in the performances of the bitumen, but also its chemical compositions. This paper carried out four-component analysis to study the influence of VOC emission from different asphalts on bitumens chemical compositions under different conditions. Results show that four-component of asphalts from different places is different. Also as the time of VOC emission increases, the total contents of resins and asphaltenes increase, but the total contents of saturates and aromatics decrease. VOC emission under different temperatures also has a great impact on the asphalt chemical components; Saturates and aromatics decrease in high temperature is larger than in low temperature, and there exists big differences in the asphalt surface layer and the internal of chemical components.
