Recent research on the impact of heavy vehicles on pavements

There are several outstanding issues related to the impact of heavy vehicles that are still not adequately catered for in the 2004 Austroads Pavement Design Guide, including the relative effects of wide single and dual tyres on performance and the lack of a rut depth model which adequately predicts the deformation performance of unbound granular pavements in service. Another trigger for this research is the recent Austroads/NTC project on "performance based standards for heavy vehicles". Three pavement protection standards were identified during this study (vertical loading, horizontal stress and tyre pressure) but only the vertical loading standard could be developed and even then it is still the subject of much debate within jurisdictions as to the likely impact of the introduction of this standard on pavement performance, particularly the vulnerable areas of the network. This paper summarises the research conducted by ARRB during 2003/2004 examining the effect of vertical loading on pavement performance and the influences of horizontal shear loading on surfacing performance.
