BACKGROUND
Airfield markings are critical visual cues and are vital for runways and taxiways. During airfield construction projects, it is often required to remove or obliterate the existing pavement markings and apply temporary markings. These operations can leave scarring that is visible on the airfield for years. These remaining traces of former markings can be mistaken by pilots and ground personnel as active airfield markings. The risk of confusion can be particularly high at night, on wet pavement, and during glare conditions. Better methods for applying and removing temporary markings and removing permanent markings that minimize the confusion are needed to prevent accidents and incidents.
OBJECTIVES
The objectives of this research are to prepare an airfield guidebook for airport operators to identify and develop best practices for the efficient, safe, cost-effective, and environmentally acceptable techniques for (1) permanent marking removal and (2) application and removal of temporary markings to ensure aviation operational safety and to minimize the adverse impact on airfield pavement. The guidebook should be applicable to airports of all types and sizes and a variety of geographic climates.
The guidebook should address, at a minimum:
-
Short- and long-term impacts on airfield pavement to include:
-
Concrete and asphalt
-
Joints and crack seal
-
Grooved and ungrooved;
-
Optics of temporary markings at any position (i.e., color, coverage and retro-reflectivity);
-
Applicability and practice above and beyond existing standards;
-
Options for temporary paint formulation;
-
Curing compound removal; and
-
Equipment options for temporary and permanent paint removal.
STATUS: The research is completed and publication is underway.
