Pavement management systems assist engineers in the analysis of road network pavement condition data, and subsequently provide input to the planning and prioritization of road infrastructure works programs. The data also provides input to a variety of engineering/economic analyses that assist in determining the future road network condition for a range of infrastructure funding scenarios. The fundamental calculation of future pavement condition is commonly based on a pavement age versus pavement roughness relationship. However, roughness/age relationships commonly do not take into account the pavement’s historic performance; rather, an ‘average’ rate of roughness progression is assigned to each pavement based on its current age or current roughness measurement.

This paper documents the results of a research project that involved a comprehensive evaluation of pavement performance by examining roughness progression over time with other related variables. A method of calculating and effectively displaying roughness progression and the effects of pavement maintenance was developed, which provides a better understanding of pavement performance. This in turn led to a methodology of calculating and reporting road network performance, for application to the pavement design and delivery system within Queensland, Australia. Means of using this information to improve the accuracy of roughness progression prediction were also investigated.

Citation counts are sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
