This letter updates guidance for design and construction of subsurface drainage features for Army and Air Force pavements. The guidance supersedes that portion of the guidance provided in TM S-820-2/AFM 88-S, Chapter 2 for design of subsurface drainage layers in pavements (Chapter 6) and provides guidance for all pavements located in both frost and nonfrost areas. The use of the guidance for flexible pavement roads, streets, or parking areas having a structural thickness less than 8 in. is optional.
