Abstract: Through the micro-characteristics of the polyester fiber and methyl cellulose and the DSR results of fiber-asphalt glue, this paper analyzes the influence of fibers on the high-temperature performance of asphalt glue, and systemically investigates the fibers-enhanced mechanism with the theory of interface chemistry and compound-material. The results show that the fibers can prominently improve the high-temperature performance of asphalt glue, and the polyester fiber is more effective than methyl cellulose.
