What are the classification of pavement marking coatings?
Classification of pavement marking coatings:
The traditional marking paint for room temperature solvent based road marking paint is slow in drying, short in service life and low in cost. It is still widely used in urban roads and general roads in China.
The solvent based road marking coating has high solid content, less solvent, fast drying and good anti light effect, and is widely used in high grade highway abroad.
The hot-melt reverse light road marking paint is fast, thick, long life, and good in reflective light. At present, the high grade highway occupies the dominant position in China.
The protrusion type vibration reflective marking coating is developed on the basis of hot melt type, and can be used for deceleration, vibration, warning, rain line and other purposes, with the form of ribs, round point and rain trough. At present, the deceleration line and the border line on the expressway have been widely used.
Water reflective road marking coating is generally dry and the temperature below 10 degrees is not recommended. The existing problem is the poor cohesive force and water resistance of asphalt pavement.
