There is a need to improve the Austroads procedures for mix design and structural design of foamed bitumen stabilised (FBS) materials. This final report summarises the mix design test methods developed within the context of an Austroads mix design process. The report details the construction and performance monitoring of six trial sections. It was observed that cracking was the predominant distress type and that pavement thickness design needs to consider FBS fatigue. The observed fatigue lives were reasonably consistent with the predictions of the Austroads interim method. Generally, rutting and shape loss are not dominating performance, even when the host material stabilised includes 20% recycled asphalt.
