While striping has become relatively straightforward and quick, its eventual removal is inherently more complex. Removal processes leave behind visible evidence, or scars, of the old markings in the form of color and surface texture changes, leading to concern about misinterpretation by pilots and ground vehicle operators. A literature review of several available paint removal techniques as well as previous research into their respective effectiveness was conducted. The viability of using clear coat sublayers as a means of protecting the concrete from waterblasting was also investigated. Scanning electron microscopy was employed to view the interface between paint and concrete both with and without the sublayers. The investigation found that a rough, brushed surface provides for easier removal of markings, including when the sublayer system was used. It was found that a low viscosity urethane provided good resistance against scarring due to increased penetration of the adhesive, indicating potential for the idea. Furthermore, the use of multiple sublayers proved ineffective at improving the scarring resistance of concrete.","abstract_html":"With new construction on highways and airports, temporary markings are often required to reroute traffic and maintain a level of efficiency while certain lanes and runways are out of service.
