Austroads: Transport Research and Trends
Government
Road deterioration (RD) models help in predicting future road condition and assessing maintenance needs. Austroads’ recent project updated the current Austroads RD models using the additional long-term pavement performance (LTPP) and long-term pavement performance maintenance (LTPPM) data as well as other available data, such as the traffic speed deflectometer (TSD) datasets, to improve these models’ explanatory power to support wider loading and the climate conditions observed in Australia. The updated and improved RD models can predict the impact of the wider loading and climate conditions observed in Australia.
The project produced four Austroads publications covering the updated RD models for cracking, strength (deflection), rutting and roughness. The project was managed in conjunction with the technical support of a Project Working Group sourced from industry and the road agencies. In addition, expert advice was sought from acknowledged experts in industry and academia.
Each of the reports documented a literature review of the state-of-the-art in deterioration modelling, a review of the available datasets for each of the RD models, the approach used to update each of the RD models and the validation of the rutting and roughness RD models.
This webinar with Dr Tim Martin, Ranita Sen and Tyrone Toole presents an overview of the methodology used to achieve the above objectives and the outcomes of the project.
