Abstract:

Special asphalt has the characteristics of high added value, specificity of application scenarios and great difficulty in development. The research progress of special asphalt including modified asphalt, impregnating asphalt, coated asphalt, mesophase asphalt and other types of asphalt is reviewed. Researchers should strengthen the application of characterization methods to further clarify the multi-scale variation rules of atoms, molecules and compounds in the production process of asphalt products, so as to regulate the key technological conditions in the development and production process. According to the characteristics of different raw materials, it is suggested to adopt suitable processing technology to produce different kinds of special asphalt, so as to realize the fine and high value-added utilization of asphalt resources.

Key words: Special asphalt, Modified asphalt, Impregnating asphalt, Coated asphalt, Mesophase asphalt
