This report documents the process of assembling and reviewing the RMS NSW cracking data and the analysis of this data and its associated variables of climate, traffic load and pavement strength which has led to the development of a potential road deterioration cracking model under accelerated traffic load and deterioration conditions. A road deterioration cracking model is fully documented and compared with the current model which was based on the DPTI SA cracking data measured by the RoadCrack device.
