ARRB, in conjunction with three rural based shires in the Australian states of Victoria, Queensland and New South Wales (NSW), has completed a four-year study of the performance of unsealed road samples in these shires. The study aimed to quantify the immediate and longer-term impact of grader blading and surface re-sheeting on unsealed road performance. Measurement of base line road roughness, using a Roughometer, was undertaken on selected survey sections in each unsealed road network. These sections were selected on the basis of a pre-existing maintenance works program. Roughness was measured before and after the maintenance works. Other variables influencing performance were also quantified including traffic and climatic conditions. The study involved data assembly, performance analysis and documentation of the resulting refined models derived from roughness data collected to improve the existing road deterioration (RD) and works effects (WE) models. A piecewise regression approach was applied to the roughness data before and after maintenance. This approach generated more meaningful WE models that can be made available to local government to improve their asset management capability on unsealed roads.
