  • This study focuses on calibrating and validating performance models for pavement in Michigan and provides testing protocols for field and laboratory material testing. The research team selected various new and rehabilitation projects for flexible and rigid pavements to evaluate previous calibration efforts, verify global models in the Pavement-ME, perform local calibration, and provide suitable calibration coefficients for different pavement types. The Report documents the calibration results, input data, future local calibration guidelines, and data needs. The study estimated the resilient moduli of different pavement layers using various field and lab tests. The laboratory-determined median subgrade moduli range between 12 to 17 ksi, while the subbase moduli range between 15 to 25 ksi. FWD data analyses resulted in the highest moduli values, whereas LWD resulted in the lowest ones for all pavement layers. The surface absorptivity data collected showed a difference between old and new HMA and PCC layers. The material characterizations for HMA, PCC, and unbound materials validated the design values used for various pavement layers. Finally, the study includes the protocols for in-situ testing frequency and material sampling quantity and frequency for collecting material library data in the future.
