A Review of HDM/dTIMS Pavement Models Based on Calibration Site Data

A Review of HDM/dTIMS Pavement Models Based on Calibration Site Data

This study examines pavement deterioration models used in New Zealand. Local models, as well as models based on HDM-III and HDM-4 were examined. The research focused on how the various models were calibrated with a focus on the model for the development of cracks, which the authors identified as a crucial component of pavement deterioration. The models showed that once a crack initiates, the pavement will begin to deteriorate much more rapidly, even with a resurfacing, emphasizing the importance of crack-prevention.
