Abstract: Quick-drying waterborne coating technology is environmental-friendly and can improve road safety for its long-lasting adhesion to glass beads，high retro-reflectivity，good night visibility and high wear resistance. It occupies a leading position in road marking
materials profit from its high construction efficiency and low comprehensive cost. In this paper，the application characteristics of four major road marking coatings such as hot melt，solvent-based，water-based and two-component were summarized. The quick-drying acrylic latex for waterborne road marking coatings and its technical requirement were introduced emphatically，and the existing application problems and reason were analyzed.

Key words: road marking coatings, waterborne, acrylic emulsion, safety, long-term retro-reflectivity, retroreflection brightness coefficient, quick-drying
