The main application of urban road traffic markings lies in the surface of roads, which are subject to long-term exposure to sunlight, rain, wind, snow, and freezing, as well as impact wear and tear from vehicles. Therefore, it is necessary to pass the quality standards of markings, road markings, hot melt markings, traffic warning lines, and hot melt parking space markings. The basic requirement is that the drying time for marking must be short and the operation simple, in order to reduce traffic interference during construction; Secondly, the reflective ability of the markings should be strong enough, with bright colors and strong reflectivity, ensuring good visibility both during the day and at night; The performance should have strong anti slip and wear resistance to ensure driving safety and service life.
Parking lot itself is a kind of public resource of society, and also a place that must exist in modern society. Otherwise, our traffic will be in chaos. Everything needs to pay attention to ways and methods. Parking lot marking also needs to have certain rules and attention, and there are many standards to follow, such as roadway width gradient marking.
Hot melt marking operation process:
1. Firstly, measure and set out according to the dimensions of the design drawings. Control points are set every 50M along the line, and encrypted points are used for curve sections. A point is set every 10M, and then marked with chalk as the reference point for the marking.
After setting the reference point, place and fix it along the reference point with a marking rope. Ensure that the line shape is straight and smooth while ensuring the size of each reference point. Then draw a reference line, and the dashed and solid lines in the carriageway section shall be based on this reference line.
3. After the datum line is demarcated, the road surface can be cleaned. In order to ensure the quality of marking construction and the effective combination of marking paint and asphalt pavement, the road surface must be cleaned with shovel and broom before marking construction. If necessary, the road surface must be washed with water to make it clean and free of debris, but the construction can only be carried out after the road surface is completely dry.
4. Before applying the markings, spray primer on the application area of the markings to fully ensure the adhesion between the markings and the road surface. At the same time as applying the primer, add the coating to the hot melt to fully melt it for application. The heating temperature of the coating must exceed 180 degrees
5. The marking application is carried out using a marking machine. After the coating is dissolved, place it in the marking machine to prepare for marking. Before marking, the flow rate of the marking machine funnel should be adjusted to ensure the coating thickness and ensure that the marking thickness meets the design requirements.
6. The marking machine should move forward at a constant speed along the reference line without bending. After the cold film condenses, there should be no wrinkles, spots, bubbles, cracks, shedding, and no surface sticking phenomenon.
7. The spraying construction of the markings should be arranged during the day, and construction should be temporarily suspended during rainy days, heavy dust, and strong winds.
8. When spraying markings, appropriate warning signs should be set up on the construction site to prevent vehicles and pedestrians from passing through the work area, prevent them from taking out the paint or forming ruts, until the markings are fully dry.
9. During the construction process, self check at any time and notify and cooperate with the supervision department for spot checks. The width error of the marking should be controlled within 5mm, the length error should be controlled within 50mm, the longitudinal spacing error should be controlled within 50mm, and the lateral deviation error should be controlled within 30mm. The hot melt reflective coating used by experts in Guifeng Road Marking is one of the widely used road coatings, which ensures that all indicators of the marking meet the standard requirements. It is a solid powder coating that is coated on the road surface using specialized equipment in a high-temperature melting state. The product has the advantages of simple construction, strong adhesion, good wear resistance, strong stain resistance, bright color, and excellent aging resistance. It also has good compressive and impact strength, excellent cracking resistance, and is suitable for use on various road surfaces.
