The development of a fatigue transfer function for in situ foamed bitumen stabilised pavements

Colin Leek, Hamid Nikraz and Amin Chegenizadeh

Abstract

This report reviews the results of research undertaken into the stiffness and fatigue performance of in situ foamed bitumen stabilised pavement materials at various sites in the Cities of Canning and Gosnells in Western Australia. The aim of the research was to assess if a design relationship could be developed to predict the fatigue life of in situ foamed bitumen stabilised pavements and if the visco elastic properties of the bitumen binder were reflected in the stiffness and fatigue performance.
