This document is divided into five parts. The first part deals with flotation
analysis features and definitions to acquaint the engineer with elements
common to the various methods and the meanings of the terms used. The second
part identifies and describes the various methods used. To accomplish the
minimum intent of this document, techniques could be limited to those needed
for flotation analysis only; however, because of the close relation between
flotation analysis and runway design, methods for the latter are also
included. In fact, runway design criteria are used for flotation and
evaluation in some cases, and are periodically the governing procedure in
specific, if isolated, instances. From time to time, it may be necessary to
deal with runways built to obsolete criteria. Therefore, a listing of most of
these constitutes the third part. The fourth part of this document tabulates
the recommended documents, categorizing them for commercial and civil versus
military usage, by military service to be satisfied, and by type of pavement.
The document concludes with brief elaborations of some concepts for broadening
the analyst's understanding of the subject.strRefField
