Referring to Table 2, when a small amount of ethylene vinyl acetate or a thermoplastic polyurethane resin is added, it can be seen that the adhesive strength is lowered due to a decrease in adhesion, and in the case where a large amount is included, the wear resistance is partially reduced. In addition, when the wear resistance is low, it can be seen that the glass bead particles are separated from the road markings, so that the retroreflection is also lowered. When the heat shield pigment is added without surface modification, it is confirmed that uniform dispersion of the heat shield pigment is inhibited and thus the temperature difference is large and the heat shield is low.
