Abstract

Abstract: The technical performance of SBS modified asphalt produced by Chunfengtahe base asphalt mixed by Tianzhize chemical company limited was analyzed by SHRP standard index evaluation, and the compatibility of SBS modified asphalt was tested by fluorescence microscope. At the same time, four component analysis and standard technical index evaluation in China were carried out. The results show that: the physical microcosmic distribution of SBS I-C modified asphalt is more uniform and its quality is better; the PG grade of SBS I-C modified asphalt is PG64E-28; the proportion of four components of SBS I-C in Chunfengtahe is reasonable, and the colloidal structure is stable. The technical performance of SBS I-C modified asphalt can meet the technical requirements of Chinas specifications.
