To improve the efficiency of the road transport industry, a range of mass limit increases for heavy vehicles has been proposed. Some of the options for mass increases include increasing the axle load limit, which would inevitably lead to increased road wear. New Zealand has a mass-distance road user charging (RUC) regime where the users pay for the road wear they generate, and therefore there is a need to accurately reflect the wear.
Stage 3 of this study, carried out in 2002, aimed to accurately predict road wear from various levels of loading, an accelerated loading test was undertaken at the Canterbury Accelerated Pavement Testing Indoor Facility (CAPTIF) to compare the wear generated by different levels of loading.
