Effect of Environmental Factors on Pavement Deterioration. Final Report. Volume 1 of 2. Background and Methodology

摘要

A computerized model for the determination of pavement deterioration responsibilities due to load and non-load related factors was developed. The model is based on predicted pavement performance and the relationship of pavement field performance to a quantification of level of routine maintenance. Predicted performance provides the basis to quantify total pavement deterioration due to load-related factors. Field performance measurements and a quantification of level of routine maintenance are used to quantify total pavement deterioration due to load and non-load related factors. Proportionality assumptions are made to determine pavement deterioration responsibilities based on these relationships. Volume I describes the Performance Based Approach, the theoretical basis for the model, and the methodology applied to create the computer model. Volume II presents the Software User's Manual and the BASIC source code of the computer model.
