Brief Project Description: The Vermont Agency of Transportation (VTrans) owns and maintains 3,100 centerline miles of paved public roads. VTrans annually collects pavement condition data on this network such as smoothness, rutting, and cracking. These data are stored in a pavement management system (PMS) database that uses pavement deterioration models to predict future pavement conditions. These predictions support Transportation Asset Management Plan (TAMP) related activities including reporting performance, setting condition targets, life-cycle planning, and financial planning. During this research effort, the pavement performance models in the Deighton Total Infrastructure Management System (dTIMS) will be updated using historical pavement performance data. This process will determine whether revisions to existing models are needed to better reflect deterioration trends. Additionally, new pavement deterioration models for bonded wearing course pavements and National Performance Measures (NPM) will be developed.
