Abstract:

This is Volume 2 of a two-volume report of the results of a detailed sensitivity analysis for the FHWA flexible pavement structure model VESYS IIM. Procedures were developed and applied for conducting a sensitivity analysis for the rather complex VESYS IIM that had 30 independent variables. As a full factorial consideration at only two levels would have involved some 2 to the 30th power solutions, it was necessary to screen out relatively insignificant independent variables in stages and by various methods, separate the analysis into two factorials and to use fractional factorial techniques and other carefully constructed innovations to reduce the task to a manageable level. The sensitivity analysis was completed with a very minimum of lost information despite the staggering sizes of the full factorials represented. Separate analyses were conducted for cracking damage, rut depth, slope variance, Present Serviceability Index (PSI) and Service Life. The procedures employed, details of the specific analyses and the results of the sensitivity analysis are described in this volume.
