Over the last decade a considerable amount of research effort has been focussed on the development of a repeated load triaxial (RLT) test procedure to assist practitioners in the use of natural and marginal unbound base/subbase materials in road pavements. A significant hindrance to the widespread adoption of the RLT test has been the lack of data linking the results of the laboratory test to field performance. In order to address this issue, Austroads established a research project, titled Better Basis for Bases: Optimum Use of Granular Materials . A major component of this research project entails the loading of test pavements with the Accelerated Loading Facility. This report details the construction of the test pavements.
