The main purpose of this study is to develop and optimize a luminescent road-marking paint to improve the visibility of the traditional used road-marking paint. This paint is produced with an emulsion of an acrylic copolymer containing a self-made modified luminescent powder and various additives. Experimental coatings were manufactured on a laboratory scale and applied using a brush on tinplate panels and asphalt concrete surface. Results found a series of properties which indicated that the paint made with the additives containing sodium hexametaphosphate and sodium carboxymethyl cellulose exhibited a satisfactory performance when mixed with silicone emulsion. The physical, mechanical and corrosion resistance was studied in order to evaluate the feasibility of application onto the road surface. The results show that the paint meets the basic performance requirements of road-marking paint and has little effect on the texture depth of the road surface. The luminous performance, abrasion resistance, adhesion and water resistance at room temperature meets the basic requirements for pavements.
