The development of HDM-4 technology road deterioration models for Australia's sealed granular pavements

This paper presents the current state-of-the-art characteristics, by means of re-calibrated default coefficients, for the road deterioration (RD) models for roughness and rutting progression which were shown to vary with environment and surface maintenance treatments. The RD model re-calibration used the observational data from the LTPP and LTPPM sites in conjunction with the relative performance factors estimated for various surface maintenance treatments from the ALT data. The current imitations of these revised models with the above sealed granular pavement data are stated, including those for the seal life model. As a result, the RD models are more responsive to changes in maintenance under a range of Australian climatic conditions. It was not possible to predict the impact of surface maintenance treatments, time and traffic on the structural deterioration of sealed granular pavements. Consequently, the HDM-4 structural deterioration model for sealed granular pavements could not be re-calibrated. (a) For the covering entry of this conference, please see ITRD abstract no. E212095.
