This paper describes how Avinor, which owns and operates 44 airfields in Norway, has for the past seven years worked continuously with problem issues related to runway surface characteristics. This paper presents the results from this work and special two workshops held at Avinor's Test Track for Surface Characteristics Oslo in the years 2002 and 2003. Based on the work that has been done and the fact the harmonized FAR Part 25 and JAR 25 use texture as a variable for predicting the maximum tire-to-ground wet runway braking coefficient, resulted in new method for describing surface characteristics on Norwegian airports. Hence, Avinor does not declare wet friction values for their runways. After studies of the JAR and FAR regulations and related background material Avinor decided instead to measure texture and declare these values in the Aeronautical Information Publication (AIP) for each airport. At the workshop in 2002 macro-texture were measured by 7 laser vans from The Norwegian Road Administration and the Asphalt Institute of Technology in addition to manual glass-patch method. The workshop in 2003 included micro-texture measurement (CT Meter, BP tester) and different laser devices. This paper presents the results from these two workshops and also how this method is used by airlines and Norwegian Airports to describe the surface characteristics.
