Foamed bitumen Stabilisation is an insitu stabilisation process which uses foamed, or expanded, bitumen as a binding agent. The process produces a bound pavement which acts as a flexible pavement. The process can be used for improvement of both road base and sub-base materials. The reconstruction of a road pavement can be complete within a day and the road can be reopened to traffic after the final compaction is complete with no detrimental effects on the pavement.

The application of foamed bitumen stabilisation is not limited to use on good quality pavement materials. The purpose of this project is to examine the material properties of road base materials used in foamed bitumen stabilisation, the effects on the pavement strength and the serviceability of the pavement.

The methodology used to complete this project involved a detailed analysis of road base materials used in foamed bitumen stabilisation from various sites in New South Wales, Queensland and Victoria. This analysis involved conducting a number of tests on samples from different sites along Eastern Australia and using some historical data from testing conducted over the last 15 years.
The key outcomes of this project are to determine the effects of variations in material properties, bitumen content and if marginal materials can be successfully used in in foamed bitumen stabilisation.
