The purpose of this report is to provide an overview of the Pavement Maintenance database creation, including documenting the cleaning and filtering of the results. The analysis was performed on SA, VIC, NSW and QLD datasets to identify relationships between periodic maintenance (resealing, surface corrections, patching, etc.) and road condition/usage. A state-of-the-art method of analysis referred to as the minimum message length tool developed for the project (MML NTC) was used specifically for this analysis and is documented within the report. The Database, a joint Austroads/NTC funded Project, was developed for the State Road Authorities (SRA) of New South Wales, Victoria, Queensland, Western Australia, South Australia, Tasmania and the Northern Territory.
