Abstract

The aim of the pilot study was to investigate the underlying reasons for past pavement rehabilitation, reconstruction and replacement projects. The study was based on the data from two Australian study areas: a city based rural district of a state road authority and the whole road network of a separate state road authority. The study showed, on the basis of the two study areas, that the reasons for replacing pavements very much depend on the following: (1) the current condition of the road network; (2) the variation (increase or decrease) in traffic load from that envisaged during the design of the pavement; and, (3) geometric standard (width and/or alignment) considerations. It was apparent from the data collected that most, if not all, pavements were rehabilitated before any limiting or threshold distresses were reached, and that a pavement was apparently considered to have structurally failed by decision makers at the time that designated levels of service for the pavement were reached.
