Thermoplastic road marking paint, also called hot melt marking paint, is a kind of powder paint. When applied as road surface markings, a hot melt kettle then becomes a hard, polymer line after cooling. This paint is a thick coating as is wear-resisting, bright, and reflective. In recent years, practical applications tests have proved that the marking lines lack surface roughness and can easily cause wheel slip, resulting in a traffic accident in snow and rainy weather. Therefore, some countries once restricted the use of this paint. In order to increase the antiskid performance of the line, thermoplastic paint has
