The road marking coating has already formed a very large industry, and at present, in order to meet the use requirements of different regions, different climates and different construction environments, the road marking coating is gradually developed from low grade to high grade and from single function to multi-function direction.
Road markings are classified according to the type of coating used: normal temperature solvent type marking, heating solvent type marking and hot melting type marking. The hot-melt type road marking paint is developed successfully in Europe in the middle of the 50 th century, and is used in China after the 90 th century, and the hot-melt type road marking paint has the biggest characteristic that the coating thickness is about 1.5-2.5mm, which is 10 times of that of a normal-temperature solvent type marking, so that the hot-melt type road marking paint is more suitable for urban main roads with large vehicle flow, high-grade roads and the like, and the hot-melt type paint is basically adopted in the construction of newly-built highway pavement markings in China at present.
