Abstract:

A sound basis for estimating load-related road wear costs due to the passage of heavy vehicles on the road network is needed for the implementation of varying heavy vehicle road user charges on Australia’s arterial roads. As road roughness is considered to be a good measure of the functional condition of the pavement, it can also be assumed to be a proxy for the measure of road wear. An equation for estimating load-related road wear was derived for uncracked reasonable quality sealed unbound pavements typical of Australia’s sealed road network using a component cumulative roughness deterioration equation based on observational and experimental data for the gradual deterioration phase of sealed granular pavement life. This equation gave varying estimates of load wear with changes to the traffic load, pavement strength and the environmental coefficient and was also found to give different estimates of load wear than that provided by an equation based on the HDM-4 incremental component roughness deterioration model. A review of environmental term in the roughness deterioration equation for sealed granular pavements confirmed that this term is more appropriate in a linear form than the non-linear form used for this term in the HDM-4 roughness deterioration equation. This outcome also implies that the roughness deterioration equation developed for sealed granular pavements is likely to be more appropriate for predicting Australia’s sealed granular pavement deterioration than the HDM-4 incremental component roughness deterioration model which was originally based on the deterioration of asphalt bound pavements.
