THE USE OF LOCAL MATERIALS FOR LOW COST ROADS IN AUSTRALIA

The report discusses those features of Australia which have influenced the development of its low cost road system. Particluar emphasis is placed on the prevalence of heavy clays and the absence of local land rock in many areas. The report then describes the development of some special techniques for pavement design for the selection and assessment of materials and for the construction of the low cost roads essential to Australia's development. The techniques discussed were developed for arid inland roads with low traffic volumes. The role of some major ARRB field test programs in this development is then outlined. Special techniques resulting from this situation are described with respect to design (unsaturated conditions), materials (relaxed conditions) and construction (e.g. surface seals). The basic aim was to make best use of local conditions and it is shown that the carefully controlled use of what would normally be regarded as inadequate materials can result in sound roads. /Author/
