| Profile 1 | Walk-behind mechanical scarifier | Rotating cutter or flail assembly mechanically abrades the marking. | Short line sections, parking areas, intersections, and localized repairs. | Compact, operator-guided machine; typically powered by an internal-combustion engine or electric motor. | Cutter selection and working depth affect removal quality and the amount of surface texture left behind. |
| Profile 2 | Ride-on shot-blasting system | Propelled abrasive media strikes the marking; a recovery system collects the media and debris. | Large paved areas and removal work where a textured surface is acceptable or required. | Self-propelled unit with an enclosed blast head, abrasive circulation, and dust collection. | Surface texture, dust control, and abrasive recovery should be considered, especially near traffic or sensitive equipment. |
| Profile 3 | High-pressure water-jet system | Pressurized water dislodges paint or marking material from the pavement. | Roadway markings and other applications where mechanical abrasion should be limited. | Truck-mounted or trailer-mounted system with a pump, water supply, and collection equipment. | Water supply, wastewater recovery, operating pressure, and pavement condition influence the process and result. |
| Profile 4 | Diamond-grinding machine | Rotating abrasive tooling grinds markings from the surface. | Small-to-medium removal areas, edge work, and controlled removal on concrete or asphalt. | Hand-guided or walk-behind equipment with interchangeable grinding heads. | Tooling and pass depth should be matched to the pavement; excessive grinding can damage or unevenly profile the surface. |
| Profile 5 | Road-milling and grooving equipment | A rotating drum with cutting teeth removes marking material and, where needed, a shallow layer of pavement. | Long-line removal and thicker or strongly bonded marking materials. | Self-propelled or vehicle-mounted unit with adjustable cutting depth and dust-control options. | Depth control is important to avoid unnecessary pavement removal; the resulting surface may require cleanup or repair. |
| Profile 6 | Handheld marking-removal grinder | Abrasive discs or cups mechanically remove paint and residual marking material. | Small markings, symbols, corners, and areas inaccessible to larger machines. | Portable electric or pneumatic tool with replaceable abrasive attachments. | Suitable for detailed work, but generally slower over broad areas; dust extraction and personal protective equipment are important. |
| Profile 7 | Thermoplastic marking removal unit | Mechanical cutters, scarifiers, or milling tools break up and remove thicker thermoplastic markings. | Raised or thick thermoplastic lines, symbols, and intersection markings. | Heavy-duty walk-behind or ride-on machine with robust cutting components. | Thermoplastic thickness and adhesion can vary; tooling wear and pavement protection should be monitored. |
| Profile 8 | Combined scarifying and vacuum system | Mechanical abrasion removes the marking while integrated suction captures dust and loose debris. | Urban roads, enclosed work zones, and projects with stricter debris-control requirements. | Scarifying head connected to an onboard or auxiliary industrial vacuum and filter unit. | Filter capacity, maintenance, and appropriate dust-control practices affect continuous operation. |
| Profile 9 | Laser marking-removal system | Controlled laser energy removes or alters marking material through thermal interaction. | Specialized, precision-oriented removal work and selected pavement-marking applications. | Integrated laser source, scanning or control components, and protective enclosure or shielding. | Effectiveness depends on marking composition and surface conditions; laser safety controls and trained operators are essential. |
| Profile 10 | Multi-purpose pavement maintenance machine | Interchangeable attachments perform scarifying, grinding, or related surface-preparation tasks. | Contractors handling varied line-removal jobs, localized surface preparation, and maintenance work. | Compact power unit with replaceable heads or attachments for different pavement tasks. | Attachment compatibility, changeover time, and the requirements of each job should be checked before operation. |
