Thermoplastic Road Marking Application Techniques
Thermoplastic Road Marking Application Techniques
Road traffic markings include various lines, arrows, and text symbols applied to road surfaces. These markings serve as visual guides, warnings, and directional indicators, effectively organizing traffic and conveying essential information to drivers and pedestrians. The screed method for thermoplastic road marking application is a widely used technique, suitable for asphalt and concrete roads, as well as residential areas, hotel driveways, and parking lots.
How Screed Thermoplastic Road Marking Works
The screed method involves using a hydraulic thermoplastic preheater and a manual push marking machine. The preheater melts the thermoplastic material, which is then transferred to the marking machine for application. The principle is similar to plastering a surface, where the marking machine has adjustable side blades that control the thickness of the applied material, ensuring a uniform and smooth finish.
Application Process
During application, the thermoplastic marking material is heated to a temperature range of 180-220°C. The process follows these steps:
- The solid powder thermoplastic material is placed into the preheater and melted into a liquid state.
- The molten material is transferred to the insulated reservoir of the push marking machine.
- The heated material is guided into the screed box, which maintains its molten state.
- Once the marking process begins, the screed box is adjusted for the correct ground clearance, allowing the thermoplastic material to flow evenly onto the road surface.
- The material spreads under its own weight, forming a precise and uniform marking.
- Simultaneously, reflective glass beads are evenly distributed onto the fresh marking to enhance nighttime visibility.
