SENSITIVITY ANALYSIS OF FHWA STRUCTURAL MODEL VESYS II. VOLUME 1. PREPARATORY AND RELATED STUDIES

This is Volume 1 of a two-volume report and includes the results of studies preparatory to a detailed sensitivity analysis for the FHWA pavement structural model VESYS IIM, comparisons of predicted and measured pavement performance and recommendations for improvements to VESYS IIM. Volume 2 reports the results of the detailed sensitivity analysis itself. VESYS IIM is a comprehensive but very complex computer program currently requiring some 67 input values, about 27 of which are program control variables and the rest actual independent variables. Comparisons of VESYS IIM predicted responses to those actually measured for certain AASHO Road Test and Brampton Test Road Sections were made to test VESYS IIM capability for rational predictions. The effort is discussed in detail, and the results are presented.
