How to remove pavement marking tape?
As a professional supplier, I have compiled a list of commonly used methods and techniques for removing road markings. You can easily understand how to choose them at a glance.
| Method categories | Specific methods | Applicable markings/road surfaces | Advantages | Disadvantages/Precautions | Key points of operation |
| mechanical removal | Grinding/milling method | Most markings; Both asphalt and cement pavements are suitable. | Fast speed, thorough effect, commonly used in cities. | The noise is loud and there is a lot of dust, which may cause slight damage to the road surface. | Control the depth and angle of mechanical cutting to avoid excessive damage to the road surface texture. |
| Shot blasting/sandblasting method | Thin layer marking; The cement pavement has a particularly good effect. | Fine cleaning, capable of synchronously cleaning the road surface. | Low efficiency, high cost, and troublesome steel shot recycling. | Adjust the specifications of the pellets and spray pressure to find a balance between clearing the markings and protecting the road surface. | |
| Physical/Thermal Clearance | Physical/Thermal Clearance | Thicker hot-melt markings. | Simple tools and flexible maneuverability. | Only for hot melt marking, there is a safety hazard of open flames and special approval is required. | Strictly control the flame temperature and time, shovel as soon as it softens, to prevent burning of the asphalt on the road surface. |
| Heating shovel method | Newly constructed, thicker hot-melt markings. | Strong targeting. | There is a lot of residue after shoveling, which can easily pollute the road surface and has a narrow range of applicability. | Used for emergency response, non-standard clearance process. | |
| Chemical cleaning | Coverage method (special materials) | The old markings on the newly paved asphalt pavement may need to be quickly covered. | Almost zero damage new road surface, strong coverage, and wear resistance. | Essentially covering rather than clearing, the material cost is relatively high. | Use professional materials (such as water-based epoxy emulsified asphalt) to ensure a strong bond between the covering layer and the road surface. |
| Blacking method | Temporary concealment. | The fastest and most cost-effective. |
Extremely short-lived, the original line will reappear after the paint is worn off, which is irre
gular.
|
Only used for extremely short-term emergency response and not as a clearance plan. | |
| High pressure water cleaning | Pure high-pressure water jet | Solvent based, water-based, and partially hot-melt marking. | No dust, no chemical pollution. | High water consumption, limited effect on thick hot-melt marking. | It is necessary to cooperate with the sewage recycling system (such as the reflux pipe) to avoid secondary pollution. |
| Pre mixed abrasive jet | Various stubborn markings, especially old thick markings. | Environmentally friendly and efficient, with strong cleaning power and minimal damage to the road surface. | The equipment is expensive and requires high technical parameters (pressure, target distance, speed). | The future development direction requires professional equipment and training. |
Eradicating road markings is a technical task, with the core being the identification of targets, matching methods, and safety and environmental protection. Nowadays, technology updates rapidly, and new things like abrasive water jets and special covering materials have good effects and minimal damage. They will definitely become more and more popular in the future.
