Surface texture, including microtexture and macrotexture, is directly relevant to safe takeoff and landing operations. Antiskid surfaces provide a high skid resistance and allow safe operation of aircrafts. The surface texture should be sufficiently high to allow directional control of aircraft during landing and efficient braking over the available runway distance. Antiskid layers with tar-containing binders have good surface texture, excellent adhesion properties and have an extremely high fuel resistance, which make them more suitable for airfields than other surface treatment materials. However, tar-containing antiskid mixtures have a high Polycyclic Aromatic Hydrocarbons (or PAHs) content, which makes them toxic. Because of this environmental concern, tar-containing antiskid runways will not be allowed anymore after 2010 in the Netherlands. Therefore alternatives need to be developed. As a benchmark for the alternatives, various properties of tar-containing antiskid surface layers need to be evaluated, especially the surface texture. This paper presents texture data gathered from a number of airports in the Netherlands. All the antiskid layers contain tar and are laid between 1989 and 2009. Nano CT scanning, microscopy and sand patch tests were used to evaluate the surface textures. The results indicate that the tar-containing antiskid surfaces have a high texture depth. These high values remained constant after 20 years service.
