The visual survey of surface damage and its interpretation are the first step of investigation that an airport operator must take to assess the level of degradation of the runways he has to maintain to ensure flight safety and adequate pavement asset management.
In addition to its purpose as catalog, this guide is a tool:
- to help define and improve the working methods for surveys and their interpretation,
- reduce the dispersion in the surveyed data by limiting its subjective nature.
Guidelines are also available for flexible pavements to determine the types of works and response times for maintenance.
