Stabilised materials guidance updated

26 March 2019

Austroads has published an updated edition of the Guide to Pavement Technology Part 4D: Stabilised Materials.

Stabilisation may be defined as a process by which the intrinsic properties of a pavement material or earthworks materials are altered by the addition of a stabilisation binder or granular material to meet performance expectations in its operating, geological and climatic environment.

The use of stabilisation technology for stabilising and recycling materials for pavement construction and maintenance is widely accepted as a cost-effective method of improving long-term performance and reducing whole-of-life costs of modern, heavily-trafficked pavements.

Guide to Pavement Technology Part 4D: Stabilised Materials describes in detail the:

This Guide is a complete revision of edition 1.0 originally published in 2006 and includes restructuring the Guide based on stabilisation materials; editorial changes and minor technical changes throughout; and major technical changes to the guidance relating to cementitiously stabilised materials and foamed bitumen stabilised materials.

Stabilisation of unsealed roads is described in Guide to Pavement Technology Part 6: Unsealed Roads

The Guide was authored by Geoff Jameson from ARRB and the project manager to update the Guide was managed by Graham Hennessy.

PDF version of the Guide is available to download for free.

The online version of the Guide is being developed and will be available in April 2019.
