Abstract : Analyzing Falling Weight Deflectometer (FWD) measurements is one of the most important problems faced by transportation engineers. Most of the back-calculation programs which use these measurements, do not give unique or similar modulus values for a given pavement system. The main objectives of this research were: 1) To conduct a sensitivity analysis of a number of selected back-calculation programs, 2) To determine the ability of these programs to back-calculate assumed moduli values based on a deflection basin that was calculated using the assumed moduli values. Six back-calculation microcomputer programs were selected and evaluated. Comparison of the results shows that CHE VDEF and ELSDEF programs are in general more reliable than other programs and can be used to back-calculate moduli without substantial errors.
