Abstract
Pavement management systems assist engineers in the analysis of road network pavement condition data, and subsequently provide input into the planning and prioritisation of road infrastructure works programs. The data also provides input into a variety of engineering - economic analyses which assist in determining the future road network condition affected by 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 used in pavement deterioration and economic modelling do not take into account the pavement’s historical performance, rather, an ‘average’ rate of roughness progression is commonly assigned to each pavement based on its current age or current roughness measurement. This research project has undertaken a comprehensive evaluation of pavement performance by examining roughness progression over time and other related variables. A method of calculating and effectively displaying roughness progression and the effects of pavement maintenance has been developed, and has subsequently provided a better understanding of pavement performance. This understanding has led to a methodology of calculating and reporting road network performance, and measuring the performance of the pavement design and delivery system within Queensland, Australia. Methods of how this information can be used to improve the accuracy of roughness progression prediction were also investigated. Of particular interest to pavement asset managers should be the discussion and definition of poor pavement performance, the definition of network wide performance, the findings in relation roughness-age relationships, insight into pavement maintenance cost analysis, and future roughness prediction.
