Reflecting on the historical record of full-scale airfield pavement testing (dating from the 1940's to the 1970's), and updating the record with test-to-failure data from the FAA National Airport Pavement Test Program, the pavement life cycle relationship to aircraft loading as indexed by landing gear type (dual, dual tandem, triple dual tandem, etc.) has been revisited in this paper. The resulting collection of pavement failure data was analyzed for applicability to the existing S-77-1 methodology (using what is commonly referred to as the CBR equation). The investigation establishes that the CBR equation retains its utility for predicting pavement thickness requirements and pavement life for airfield pavements. It is concluded that the unique solution of the CBR equation at the 10,000 coverage level, for four subgrade support conditions (as defined by ICAO ACN guidelines) continues to be well suited to the use for which it was intended.
