Engineering characterisation of in situ foamed bitumen stabilised pavements

Colin Leek, Hamid Nikraz and Amin Chegenizadeh


This report is the second of two papers that 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. In the first paper “The development of a fatigue transfer function for In situ Foamed Bitumen Stabilised Pavements,” the authors reported a review of laboratory fatigue testing that was undertaken over a 13 year history.

In this paper, a review of recent work by Collings and Jenkins in South Africa where failure by shear is examined in relation to failures to date at pavements constructed in City of Canning which do support Collings and Jenkins theory.
