Historically, traffic mix analyses have been based upon the use of the critical or most damaging aircraft. The damage effects of other aircraft are either ignored or empirically incorporated into the analysis. This paper presents an alternate traffic mix analysis procedure. In it, the damage produced by any given aircraft, at any specified gross weight and operating on any given pavement system is computed. Because the proposed procedure is computationally intensive, a computer solution developed by the authors is described. Also, recommendations are provided for establishing a simplified aircraft mix damage factor identical in concept to the highway truck factor.
