Abstract：Withthedevelopmentofubanconstructionand transpoitation facilities，theperformanceandqualityrequirements ofasphaltconcretehavebecomeincreasinglystringent.Aimingatthecommonproblemsofhighviscosityandeasyadhesionof asphaltconcreteduringconstruction，thispaperiscommittedtodevelopingnewspecialwarmmixmodfiers.Throughsystematic comparativetestsonvariouswarmmixmodfierfomulasandtheirdiferentdosageamounts，theaimistodeterminean optimizedself-madewarmmixmodifierformulaanditsoptimalmixingratiotoachievethebestperformanceefect.Theresearch resultsshowthattheoptimalratioofSES：aliphaticresin：phenolicresinvulcanizingagentinthewarmmixmodifieris5：3：3，and the optimal amount is 6 % ，considering the dual effects of economy and efficiency.This result will lay a foundation for the engineering application of the warm mix modifier.
