The main role of the road markings are: the implementation of lane road, through the drawn lines on the road traffic signs to guide different types of vehicles at different speeds along a designated route prevails so as to improve road transport capacity and reduce traffic The purpose of the accident; instructions and notices to the driver through the traffic markings to predict road conditions and clarify their use and access roads of the rights and obligations and methods; for law-abiding and law enforcement to provide a legal basis.
Highway marking paint mainly using the following categories: solvent-based coatings, heat-based coatings, hot melt coating (also known as melt coatings), two-component coatings, water-based paint and other types.
The highway construction, used for traffic engineering in the road marking paint material performance requirements of a high. First requires drying time is short, simple operation, in order to reduce traffic interference; Second, the demand against the reflective ability, bright, reflective high, in order to have a good day and night visibility; third, it has good slip resistance and wear resistance in order to ensure road safety and marking life. Hot-melt-type reflective coating of its features are: a quick-drying, drying time for 1-3min. Synthetic resin will be colored pigments, physical pigments, reflective materials, combined with the road surface, with strong adhesion, stable performance, color, degree of brightness and reflective characteristics of a long time, and it has good wear resistance and slip resistance. Therefore, highway construction in China road marking materials, mainly in hot melt coatings and hot melt vibration reflective coating.
