During heating process of bituminous materials, volatile organic compounds (VOCs) will be released, and it is harmful to the skin, the respiratory and nervous system of the human body, especially increasing its carcinogenic tendency. In this study, the VOCs emission of base and modified binder was characterized as the function of typical temperatures by gas chromatography coupled with mass spectrometry (GC/MS). The rheological behavior of each binder before and after the emission of VOCs was compared. The relation between the VOCs emission of bitumen and its rheological properties was researched. The results indicated that a higher temperature can lead to increase of VOCs components of binder. The addition of SBS modifier can reduce VOCs components of its base binder. However, the degradation of the SBS modifier decreased its inhibition effect on the VOCs emission of bitumen at 220 °C. Naphthalene release and carcinogenic index of polycyclic aromatic hydrocarbons (PAHs) increased with the increase of temperature. The complex-flow activation energy ${\text{E}}_{\text{a}}$ increased after VOCs emission. Naphthalene content exhibited a better linear relation with ${\text{E}}_{\text{a}}$.

在沥青材料的加热过程中，会释放出挥发性有机化合物（VOC），对皮肤，人体呼吸道和神经系统有害，尤其是增加其致癌趋势。在这项研究中，通过气相色谱-质谱联用（GC / MS）将碱和改性粘合剂的VOC排放表征为典型温度的函数。比较了每种粘合剂释放VOC前后的流变行为。研究了沥青中挥发性有机化合物的排放与其流变性质之间的关系。结果表明，较高的温度可导致粘合剂的VOC组分增加。SBS改性剂的添加可以减少其基础粘合剂的VOC成分。然而，SBS改性剂的降解降低了其对220°C时沥青VOC排放的抑制作用。多环芳烃（PAHs）的萘释放和致癌指数随温度的升高而增加。复流活化能${\text{E}}_{\text{一个}}$排放挥发性有机化合物后增加。萘含量与${\text{E}}_{\text{一个}}$。
