The Federal Aviation Administration Airport Technology Research and Development Branch sponsored a study of pavement surface treatments with two main objectives: to identify best practices and to propose guidance for selecting surface treatments as the appropriate treatment strategy for airport pavements. Twelve airports and agencies with surface treatment experience provided information to develop case studies. Site visits were made to 11 airports, associated with 8 of the case studies, to collect additional information. This technical note summarizes key observations regarding the use of surface treatments at different airports and on different features based on those case studies. Complete case studies are included as an appendix
