Abstract：This study focuses on the analysis of theroad performance and durability of asphalt mixtures modified with PCF anti-rutting agent.Modified specimens with PCFand PR anti-ruting agents added atdosages ranging from （2 0% to 0.6% were prepared respectively，and the application performance of specimens with diferent modified materialswas tested through ruting tests，low-temperature frost resistance tests and other methods.The testresults show thatthe specimens added with diferent contents of PR anti-rutting agent have por road performance in high-temperature environments，and the flexural-tensile performance of specimens added with PR anti-ruting agent is weak in low-temperature environments;while the specimens added with PCF anti-ruting agent exhibit low permanent deformationinhigh-temperature environments，aswellashigh flexural-tensilestrainandflexural-tensilestrength.Among them，the specimens added with 0.4% PCF anti-ruting agent have high fatigue life and cumulative dissipated energy under freeze-thaw conditions，indicating that the asphalt mixture modified with 0.4% PCF anti-rutting agent has the best road performance and durability.
