Growth of aircraft to over a million pounds, with the need for many wheels to support such aircraft, has focused attention on the unduly conservative aspect of present equivalent single wheel load (ESWL) methods when applied to many grouped wheels. The assembly of all multiple-wheel accelerated traffic test data for use in reexamining ESWL methods provided an indication that the earliest multiple-wheel tests likely were treated extremely conservatively during their analysis some 40 years ago. Accordingly, these early tests (reported in TM 3-349) were subjected to a reexamination. The reexamination confirmed that the initial analysis was quite conservatively carried out. With the benefit of the added 40 years of research findings and experience with in-service pavements, a less conservative analysis can now be made and accepted with confidence. This report presents the reanalysis carried out and the revised pavement bahavior indicated.
