Title: Evaluation of in situ stabilisation for best value management of unsealed roads
Abstract: The Australian road network consists of over 500,000 km of unsealed roads, or about 60 per cent of the total road network. Approximately A$1 billion is spent annually on maintaining this network. Maintenance costs per kilometre are high; unsealed roads are also the largest consumer of natural materials in the infrastructure industry. Any contribution to reducing these two prime factors will have a significant effect on triple-bottom-line considerations (i.e cost, environment and social factors). This paper describes the evaluation of in situ stabilisation of unsealed roads in remote locations. Issues addressed include material availability and deficiency, construction logistics, binder selection, pavement performance and economic evaluation. Whilst no comparisons are made regarding the performance of each product, the paper presents a rational approach to the evaluation of material selection, processing and improvement in order to provide best value management of unsealed road network. Some statistics regarding the prevalence of unsealed roads in the region are also presented.
