摘　　要：传统煤沥青具有的对温度敏感性高、延展性差、易老化和易污染环境缺点导致其路用性能受到了限制,因此煤沥青的改性研究备受关注。综述了煤沥青物理改性和化学改性方面的研究进展,重点阐述了热塑性弹性体、橡胶类聚合物、树脂类化合物和醛类化合物对煤沥青的改性,并对煤沥青的改性机理进行了推测,在此基础上展望了改性沥青的发展趋势。Traditional coal pitch has a high sensitivity to temperature,poor ductility,easy aging and pollution of the environment. It causes that the road performance of coal pitch is limited, so the research on the modification of coal pitch is of concern. The research progress of physical and chemical modification of coal pitch was reviewed, it focused on the modification of coal pitch used the thermoplastic elastomer, polymer resin, rubber compounds and aldehyde compounds,and the modification mechanism of coal pitch was speculated. On this basis, the development trend of modified coal pitch was prospected.
