［Objective］To improve the road performance of waterborne energy-saving luminescent pavement marking coating.［Methods］Using strontium aluminate long-acting luminescent powder as energy storage and luminescent material，an aqueous pavement marking coating with energy storage，luminescent function，and excellent road performance was developed. Performance testing systematically studied theinfluence of different emulsions，fillers，and coating thicknesses on film-forming performance. An orthogonal experimental design analyzed the influence of component dosages on film formation. Extremedifference analysis determined the impact size（order of influence） of each factor on specific performance and identified the optimal combination.［Results］The optimal composition comprised： silica-acrylic emulsion（43%）as the base material，calcium carbonate（14%）as filler，deionized water（19%），a uniform mixture of luminescent powder and titanium dioxide（7∶3 mass ratio，totaling 15%）and auxiliary raw materials（9%，including dispersants，film-forming additives，sodium methylcellulose，defoaming agents，leveling agents，propylene glycol，and drying agents）. Coating thickness was optimally controlled at 0. 310 mm for line marking performance with nonsticky-to-tyre drying time of 15 min，afterglow time of 12. 5 h，excitation stops for 10 min when the luminous brightness of 341. 55 mcd/m².［Conclusion］ A waterborne energy-saving luminescent pavement marking coatingwas prepared，which could be further applied in urban roads，bridges，tunnels and other traffic facilities.
