摘要：

SBS modified asphalt (SBSMA) is widely used in asphalt pavement, but due to the characteristics of the materials and the effects of the environment and construction, the phase structure of SBSMA often under-goes adverse changes. This article reviewes the effects of SBS type and dosage, asphalt type, processing technology and environment on phase structure and separation. The correlation between the phase structure of SBSMA and chemical composition, micromechanics, rheological properties, and other aspects are analyzed. In addition, the phase structure analysis parameters of 2D image processing based on flu-orescence microscope, phase field method model, and phase prediction model are generalized. Finally, the article summarizes the phase structure stability of SBSMA mixed with various materials, which pro -vides a reference for researchers to understand the research progress in this field.
