Review of national and state-level calibrations of AASHTOWare Pavement ME design for new jointed plain concrete pavement
For the design of new jointed plain concrete pavements (JPCPs), three national calibrations of the AASHTOWare Pavement ME Design have been necessary due to model and database updates. Local calibration is also recommended to better match a state’s experience. To date, 8 states have changed the calibration coefficients to local values, while 11 states have implemented national coefficients. This study presents a review of the national and local calibrations and a comparison in terms of, (1) pavement performance prediction and (2) thickness design. It was found that the difference between the local and national calibrations was significant in terms of predicted pavement performance, but much less with respect to thickness design. Furthermore, a full factorial was conducted to study the impact of various design features on the local calibrations. The results showed that the difference between the national and local calibrations decreased as optimum design features such as short joint spacing were used.
