This report consists of 12 papers that summarize how states see good, fair, and poor pavement performance measures; modeling and analyzing budget-constrained pavement preservation strategies; using enhanced econometric techniques to verify the service life of asset interventions; and the performance and benefits of Michigan Department of Transportation’s capital preventive maintenance program. This issue also explores a Bayesian model for predicting the performance of pavements treated with thin hot-mix asphalt overlays; using multiple investigative techniques to assess flushing of chip-seal surfaces; long-term cost effectiveness of asphalt pavement pothole patching methods; and a field validation of laboratory-predicted low-temperature performance of hot-poured crack sealants. Also, this edition examines measured anchor-rod tightening of high-mast light poles in Alaska; forecasting the cost of sustaining a set of bridge connections; selection of an appropriate material, construction technique, and structural system of bridges using a multicriteria decision-making method; and a defect-based condition assessment of concrete bridges.
