Why Do Road Markings Deform? Causes and Solutions for Road Marking Machine Issues
Road markings play a vital role in guiding traffic and enhancing safety on roads, highways, parking lots, and other surfaces. However, professionals sometimes encounter issues like deformation after using road marking machines. These problems may stem from multiple factors, including equipment operation, material quality, and external conditions.
Below, we explore common causes of road marking deformation and provide practical solutions to help you achieve clean, durable, and compliant markings.
Common Causes of Road Marking Deformation
1.Poor Material Quality
Substandard thermoplastic or paint may fail to adhere properly or withstand traffic and weather exposure, leading to premature wear or deformation.
2. Improper Operation of the Road Marking Machine
Incorrect machine settings, uneven application, or inconsistent marking speeds can cause variations in line thickness and appearance.
3. Environmental Factors
Extreme temperatures, humidity, or surface moisture can disrupt the curing process and compromise final quality.
4. Road Surface Issues
Uneven or dirty road surfaces may prevent proper adhesion of marking materials.
5. Equipment Maintenance
Poorly maintained road marking machines, such as clogged nozzles or worn components, can cause marking defects.
Common Defects and Solutions
1.Tire Marks and Stains
Tire marks typically appear when traffic is allowed on lines before full curing.
Solution: Use high-quality thermoplastic marking material with appropriate viscosity and drying time. Ensure surfaces are fully dry before vehicle traffic.
2. Horizontal Streaks
These are usually caused by machine vibration, excessive material viscosity, or incorrect temperature settings.
Solution: Adjust the road marking machine’s temperature control, use a smoother application speed, and ensure the paint or thermoplastic material achieves optimal flow consistency.
3. Vertical Streaks
Burnt material or foreign objects in the paint bucket or applicator can cause streaks in the marking.
Solution: Regularly clean the machine’s sprayer and nozzles. Use filtered and thoroughly mixed paint to prevent clogging and carbonized residue.
4. Inconsistent Line Width
This is usually caused by uneven operation or machine movement.
Solution: For hand-pushed road marking machines, train operators to maintain a steady speed and height. For automated equipment, calibrate the device regularly.
5. Poor Adhesion
If markings peel off quickly, it may indicate insufficient surface cleaning or unsuitable material.
Solution: Thoroughly pre-clean the pavement and select materials designed for specific surfaces (e.g., asphalt or concrete).
