摘　　要：随着交通量的增长,对路面材料的性能要求不断提高,而石油沥青是公路中应用最广泛的材料之一。因此,为了进一步提高石油沥青的性能,必须深入理解和掌握有关石油沥青的组成、结构方面的知识。介绍了石油沥青的平均分子结构模型,以分散系统理论为前提总结了石油沥青的胶体结构模型,提出了现有结构模型的不足,并对未来的研究方向进行了展望。With the growth of traffic volume,the performance requirements of pavement materials are increasing,and petroleum asphalt is one of the most widely used materials in highway.In order to further improve the performance of petroleum asphalt,it is necessary to deeply understand and master the knowledge about the composition and structure of petroleum asphalt.The average molecular structure model of heavy oil and asphalt was reviewed,and the colloidal structure model of heavy oil and asphalt was summarized based on the theory of dispersion system.The shortcomings of the existing structural models were put forward and the future research directions were prospected.
