2008 - Australia - HDM-4 RDWE Calibration

This report documents the calibration of HDM-4 RD models for sealed granular and asphalt
pavements based on SRA historical deterioration data. SRAs supplied historical roughness and
rutting deterioration data and some supplied cracking deterioration data and maintenance history.
HDM-4 RD models were calibrated to suit conditions in Victoria, Tasmania, South Australia,
Queensland and New Zealand. Rutting and roughness RD models were calibrated for all these
SRAs, except Queensland. Cracking RD models were calibrated for South Australia due to the
reasonable quality of its cracking data. Cracking data from Victoria, Tasmania and New Zealand
were either of inadequate quality or too insignificant, in terms of extent of cracking, to be
considered in the analysis, hence cracking models were not calibrated for the data from these
authorities.
