This document presents criteria for the evaluation of the load-carrying capacity of pavements used (or to be used) for the support of aircraft. An evaluation is conducted to assess the allowable traffic that a pavement can sustain for given loading conditions or the allowable load for a given amount of traffic without producing unexpected or uncontrolled distress. This document is for use in evaluating U.S. Army, Air Force, Navy, and Marine Corps airfields and heliports and is applicable to conventional-type pavements. The procedures presented include direct sampling and non-destructive testing techniques. The document also describes computer programs that can be used for pavement evaluation.
