Sensitivity Analysis and Calibration of the Alligator Cracking Model Using Regional Data

The models used in the M-EPDG were calibrated using regression coefficients and calibration constants that were determined from data collected from all across the United States. The verification of M-EPDG with level 2 and 3 inputs for the State of New Jersey did not yield satisfactory results with respect to alligator cracking for the twenty-five sections analyzed in one of the study. It was determined that the error might be from the calibration factor or regression coefficients in the prediction model that was calculated based on the national average. The main focus of this study is to use the aforementioned twenty-five section study and four more NJDOT sections to calibrate and validate the alligator cracking model for New Jersey.
