Development of Pavement Performance Models using New Breakpoints and Pretreatment Conditions

Previous studies indicated that two factors, traffic load and pretreatment pavement condition, can have significantly impact on pavement performance and should be considered when developing pavement performance models. This study is proposed to use these two factors to develop new pavement performance models for the North Carolina Department of Transportation (NCDOT) Pavement Management System (PMS). A new traffic load indicator, other than annual average daily traffic (AADT), will be selected and then its breakpoints will be determined. These breakpoints, together with thresholds of pretreatment pavement conditions, will be used to define new pavement families; the corresponding distress and performance models will also be developed. These new models are expected to be more accurate and robust in predicting pavement deterioration trends because of the inclusion of additional pertinent factors; once the existing somewhat obsolete performance models developed using the windshield distress data are replaced by these new models, performance of the NCDOT PMS will be improved and more informed maintenance and rehabilitation decisions can be made.
