Zusammenfassung:The present application generally relates to a thermoplastic road marker having improved crack-resistance, to compositions of such road markers, and to methods of making and applying these road markers. Some embodiments of the present disclosure relate to a thermoplastic road marking composition, comprising: ethylene vinyl acetate ("EVA") and/or ethylene acrylic acid ("EAA") copolymers in an amount of between about 1.5 wt % to about 6.0 wt %; and core-shell particles in an amount of between about 0.5 wt % and about 3.0 wt %. In at least some embodiments, the EVA and/or EAA have a melt flow index equal to or less than 45 g/10 min at 190° C.
