Pavement Deterioration Models for Pavement Management
The Vermont Agency of Transportation (VTrans) oversees the ownership and maintenance of an extensive network comprising 3,100 centerline miles of paved public roads. In 2004, VTrans pioneered the development of pavement performance models, utilizing historical pavement performance data categorized by the underlying structure and paving surface treatment. Since that time, the agency introduced bonded wearing course and thin overlay paving treatments. However, there were no performance models in place to project conditions for these treatments. Additionally, Federal standards for National Performance Measures (NPMs) on National Highway System (NHS) pavements have since been established, including metrics such as rutting, cracking, and pavement smoothness. The existing VTrans Performance models already included deterioration rates for smoothness and rutting, but a model was needed for cracking that is in alignment with NPM standards. This project aimed to fill this gap by conducting a comprehensive review of the most recent historical pavement condition and treatment history data. Existing performance models were updated, and new models were established for bonded wearing course and thin overlay treatments and the NPM cracking metric.
