Embodiment 1

[0016] The road marking construction process method of the present embodiment comprises the following steps:

[0017] A. Blow the road surface to make the road surface clean, free of dust, and ensure that the road surface is dry;

[0018] B. According to the design, mark the position where the marking line needs to be marked, spray the primer, and the spraying amount is 150g / m 2 ;

[0019] C. Use a hot-melt kettle to melt the marking paint. The temperature of the hot-melt marking paint is controlled within the range of 168 ° C. The melted marking paint is used up within 4 hours, and the hot-melt marking paint is applied within 5 to 8 minutes after the primer is sprayed. Melt marking paint, apply two layers of marking paint, after the first layer of paint is dry, then apply the second layer of paint, before the second layer of paint is not dry, spread glass beads evenly, the particle size of the glass beads is 400um, Spreading amount is 350kg / m 2 , dry naturally, and the thi...

Embodiment 2

[0021] The road marking construction process method of the present embodiment comprises the following steps:

[0022] A. Blow the road surface to make the road surface clean, free of dust, and ensure that the road surface is dry;

[0023] B. According to the design, mark the position where the marking line needs to be marked, spray the primer, and the spraying amount is 165g / m 2 ;

[0024] C. Use a hot-melt kettle to melt the marking paint. The temperature of the hot-melt marking paint is controlled within the range of 172°C. The melted marking paint is used up within 4 hours, and the hot-melt marking paint is applied within 5 to 8 minutes after the primer is sprayed. Melt marking paint, apply two layers of marking paint, after the first layer of paint is dry, then apply the second layer of paint, before the second layer of paint is not dry, spread glass beads evenly, the particle size of the glass beads is 500um, Spreading amount is 350~400kg / m 2 , dry naturally, and the t...

Embodiment 3

[0026] The road marking construction process method of the present embodiment comprises the following steps:

[0027] A. Blow the road surface to make the road surface clean, free of dust, and ensure that the road surface is dry;

[0028] B. According to the design, mark the position where the marking line needs to be marked, spray the primer, and the spraying amount is 180g / m 2 ;

[0029] C. Use a hot-melt kettle to melt the marking paint. The temperature of the hot-melt marking paint is controlled within the range of 175°C. The melted marking paint is used up within 4 hours, and the hot-melt marking paint is applied within 5 to 8 minutes after the primer is sprayed. For melting marking paint, apply two layers of marking paint. After the first layer of paint is dry, apply the second layer of paint. Before the second layer of paint is dry, evenly spread glass beads. The particle size of the glass beads is 600um. Spreading amount is 500kg / m 2 , dry naturally, and the thickne...

Abstract

The invention discloses a road marking construction process method, which relates to the technical field of road engineering. The method comprises the following steps: blowing the road surface to make the road surface clean and dust-free, and ensuring that the road surface is dry; dotting the required marking line according to the design Marking, spray primer, spraying amount is 150 ~ 180g / m 2 ; Use a hot-melt kettle to melt the marking paint, apply the hot-melt marking paint within 5 to 8 minutes after the primer is sprayed, apply two layers of marking paint, and apply the second layer after the first layer of paint is dry Coating, before the second layer of coating is not dry, spread glass beads evenly, the spreading amount is 350~500kg / m 2 , dry naturally, and the thickness of the road markings formed is 2-4.5mm. The invention solves the problem that road markings are easy to crack and fall off.

Description

technical field [0001] The invention relates to the technical field of road engineering, in particular to a road marking construction process method. Background technique [0002] Road markings refer to signs that convey traffic information such as guidance, restrictions, warnings, etc. to traffic participants on the road surface with lines, arrows, text, facade marks, raised road signs, and contour marks. Its role is to control and guide traffic. . The existing road markings are sprayed on the road surface by machinery. The paint has a certain thickness, so the markings will protrude slightly from the road surface, and the adhesion between the paint and the cement road surface is relatively poor. Rain, snow and ice, and the impact and wear of various vehicles, the road markings are easy to crack, or even peel off, which greatly shortens the service life. Contents of the invention [0003] The purpose of the present invention is to provide a road marking construction pro...
