Line marking is a crucial aspect of road safety, as it helps drivers and pedestrians navigate the roads safely and efficiently. However, achieving accurate and durable line markings is not always an easy task. By implementing these Best Road Marking Practices from Lighten Traffic, you can ensure that your line markings are of the highest quality, helping to keep our roads safe and efficient for everyone.
Ensure road condition before line markings
Before starting the line marking process, it is important to check the condition of the road. Ensure that the road surface is free of water, oil, and bumps. Use cleaning machines and air blowers to clean the surface. If the road needs a primer, it can be applied using mechanical spraying or roller coating. The coating area should be slightly wider than the line marking, and the coating amount should be 8m/kg. After the solvent completely evaporates, thermoplastic paint can be used for construction.
Prepare road before construction
Measure the position of the line marking and ensure accurate marking. Use auxiliary machines such as waterline machines.
Do proper machine inspection
Before construction, check the machine, with a focus on inspecting the diesel engine, cooling water level, engine oil level, fuel level, road marking machine, and coating machine (scraper, the spray should be adjusted according to the thickness and line width), and glass bead dispensing machine (check whether the glass beads are uniform and the quantity is sufficient, whether the pipeline is blocked).
Monitor road temperature
Monitor the temperature of the air and road surface at all times to ensure that the construction temperature is higher than the outdoor temperature by more than 3 ℃. When the road surface temperature is below 9 ℃, be cautious about construction! The heating temperature of the preheater should be determined according to the weather conditions during construction. When the temperature is too low, the heating temperature should be appropriately increased. When the temperature is too high, the heating temperature should be reduced.
Control heating temperature of the preheater for the coating
The coating in the preheater or construction vehicle should not be overheated, and the temperature of the coating should not exceed 220 ℃! Be cautious when the thermometer fails! Stir the coating evenly in the preheater and maintain the required viscosity and temperature. High temperatures will make the coating thinner, and long-term heating will change the color of the coating. After the coating melts, continue to stir for about 10 minutes to discharge the coating.
Adjust the blade on the molded boot of the line striping machine appropriately
The rear blade makes the line surface smooth, and the edge blade makes the line edge clear and neat. The thickness of the line can be changed by adjusting the position of the rear blade on the molded boot. The closer the rear scraper is to the road surface, the thinner the line, and the farther away it is, the thicker the line. Ensure that the height on both sides is consistent. Clean the residual coating at the bottom of the rear blade of the mold frequently to avoid leakage of paint due to the gap of the blade and the rough surface of the line marking.
Control Line striper walking speed
The thickness of the line depends on the walking speed of the line-marking personnel. The faster the walking speed, the thinner the coating on the road surface, and vice versa. The slower the walking speed, the thicker the coating on the road surface.
Conclusion
In conclusion, the quality of line marking on roads is affected by various factors, and it is important to pay attention to every detail from preparation to construction. Checking the road condition, inspecting the machine, monitoring the road temperature, and adjusting the heating temperature of the preheater are all crucial steps to ensure the success of line marking. Additionally, adjusting the position of the rear blade on the molded boot, controlling the walking speed of the line marking personnel, and cleaning the residual coating at the bottom of the rear blade of the mold frequently are also important practices to ensure the line marking quality. By following these practices, we can achieve accurate, clear, and durable line markings on roads, ensuring the safety of drivers and pedestrians.
