Abstract: This investigation was conducted to develop structural requirements (minimum cover tables) for buried pipe beneath flexible- and rigid-pavement, landing-mat-surfaced, and unsurfaced airfields subject to operations of the C-5A and other aircraft in the theater of operations. Present design practices were reviewed, and computer programs based on the present design practices were written and used to predict pipe behavior under various loadings. Stress-at-depth data from full-scale load cart tests, field surveys, and tests of pipe subjected to the C-5A and other loadings were analyzed, and the field behavior was compared with predicted behavior. Minimum pipe-cover requirements were developed for rigid and flexible pipe buried beneath airfields to be subjected to operations of the C-5A and other aircraft. These pipe-cover requirements are intended for use in conjunction with Department of the Army TM 5-330/AFM 86-3, Vol II, "Planning and Design of Roads, Airbases, and Heliports in the Theater of Operations", but because of their general nature, the cover requirements are applicable to all airfields.
