Stabilisation Fundamentals (1 Day) - Face to Face

This practical face to face course will briefly review the types of stabilisation before more detailed presentations on types of binders, material characteristics, design and mix detailing. Another feature of this course is its significant practical and project-based content which aims to provide advice on road stabilisation solutions.



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

Overall the Course will include discussion on the types of various stabilising binders used in road construction, their properties, manufacture, and chemical reactions during the stabilisation process and safety considerations associated with their use. The types of binders described are lime, cement, cementitious pozzolans, bitumen, chemical and synthetic polymers.

The Austroads Guides to Pavement Technology – Part 4D, Stabilised Materials, Part 4E, Recycled Materials, Part 4L, Stabilising Binders, and Part 6: Unsealed Pavements as well as the AustStab Pavement Recycling and Stabilisation Guide are used as the key references.

PLEASE NOTE: Hard copies of the AustStab ‘Pavement Recycling and Stabilisation’ and ‘Insitu Stabilisation Construction' Guides will be provided on the day of the training.

Topics Covered:

  • Setting the scene: Types of Stabilisation Undertaken
  • Binder Types  (Review)
  • Material Mix Design
  • Austroads Structural Design of Pavements
  • Structural Design of Lightly-trafficked Stabilised Pavements
  • AustStab Low Traffic Design Methodology
  • Lime Stabilisation of Subgrades (part 1 & 2)
