Introduction of road marking construction method?

Combined with the specific situation of road construction in China, what is the general method of road marking construction in China at this stage? What is the basic profile? The following is the basic introduction of Zhong Da Consulting on the road marking construction method:

What is a road sign?

Road marking: hot melt marking, cold paint marking at room temperature, color anti-skid marking, oscillating anti-skid reflective marking and prefabricated marking, also known as road marking. Refers to the signs that convey traffic information such as guidance, restriction and warning to traffic participants with lines, arrows, characters, elevation signs, prominent road signs and markings on the road surface. Its function is to control and guide traffic, and it can be used together with signs or alone.

At present, hot melt marking is one of the most widely used marking types in China. Zhong Da Consulting takes specific construction implementation rules as an example, and the basic contents are as follows:

The construction method of melt coating is actually a welding operation, so the material performance, construction method and technology directly affect the coating performance. There are various construction conditions and pavement conditions, and the factors affecting the performance of pavement markings are also ever-changing. Therefore, every construction should try to control various factors and strive for good construction quality.

Construction method of road marking-hot melt marking

Construction process:

1, reflective hot-melt marking, glass bead primer and petroleum resin hot-melt coating.

2. Heat the coating in a hot-melt machine, control the melting temperature between 180 ~ 220 degrees Celsius, and fully stir for about 10 minutes before painting.

3. Mark the position and measure it according to the position and figure shown in the design drawing, and then apply primer on the marked drawing.

4. Hot melt coating can only be carried out after the primer is dried. When marking, reflective glass beads are laid to increase night recognition. The marking thickness is1.5—1.8mm. ..

Basic advantages and disadvantages:

App application

Hot melt marking is the most widely used marking on road marking in China at present.

superiority

Short construction time, high wear resistance and low cost.

Use special cold paint for road, spray it manually, with uniform thickness and clear color.

Main applications

Including parking spaces, no parking yellow line areas, traffic lines, diversion zones, guiding arrows, etc.
