Road traffic marking is a traffic safety facility made up of various lines, arrows, words, elevation marks, protuberance signposts and contour marks on the road. Its role is to control and guide traffic. It can be used in conjunction with signs and can be used separately.
The function of the ground marking is to inform drivers of traffic, prohibition, restriction and other provisions of road traffic. Drivers and pedestrians must strictly observe the marking instructions. In the course of road line construction, there are some problems, which affect the quality and beauty. In the construction of Shenzhen Peng Xiang professional team, the following problems are summarized and the treatment methods are put forward.
1. the phenomenon of peeling on the surface of the road surface can adjust the formulation of the coating, increase the cohesive force and flexibility.
2. road cleaning are not thoroughly, or not use paint. Construction should be strictly carried out according to construction procedures to ensure construction quality.
3. when the coating is applied for a long time without drawing line (or in wind sand weather construction), it is easy to stick to dust, which will cause the peeling off of the marking line, and the marking line should be drawn immediately after the coating is dry.
4. the road coating layer is affected by the moisture level of the road surface. There is water on the road surface, or it is relatively humid. Measures must be taken to build the road after drying. Ensure the pavement construction should be dry, in special circumstances must work by artificial drying method.
5. when the ambient temperature is below 5 C, the quality of the construction is unstable. It is easy to cause peeling off, and the melting temperature is too low, which will seriously affect the cohesive force between the marking and the road surface.
6. the road coating is not fully melted and the mixing is uneven. During construction, the coating should be fully melted, fully stirred and cooked before coating.
7. cement pavement covered the improper selection of new cement road surface due to the presence of high alkaline and brittle layer, easy peeling off.
