Webinars on best materials for sealed and unsealed roads

SELECTING the most appropriate materials for road construction or maintenance requires a complex assessment of performance, life-cycle costs, and sustainability.

With increasing shortages of quality quarried materials and natural gravels, road agencies are needing to consider how locally sourced marginal and non standard materials can be used effectively.

"The performance of unsealed and sealed roads is critically dependent on materials used. Road asset managers need to understand the mechanisms behind material performance to select and tailor materials for a range of different applications," said Ross Guppy, Austroads Program Manager Assets.

To extend practitioners' understanding of what influences material performance, Austroads will run a series of webinars based on the reports 'Sustainable Roads Through Fit-for-purpose Use of Available Materials: Evaluation Tool and User Guide' and 'Sustainable Roads Through Fit-for-purpose Use of Available Materials: Technical Basis'.

The user guide provides step-by-step guidance to help practitioners assess available materials and select those that are suited to the chosen design application therefore optimising budget resources while continuing to meet a required quality level.

The content of the webinars will be focused on the material assessment and life-cycle costing frameworks and their application to sealed and unsealed roads.

Speakers from ARRB's Asset Management and Future Infrastructure teams, local government and industry will provide greater detail into the use of the frameworks and demonstrate their effectiveness through several case studies.

The first session will cover the materials assessment framework in detail and how it can be used to undertake resource assessment.

In the second webinar participants will learn how to assess the best use of available marginal and non standard materials for sealed roads while the final session will highlight the important components that are considered for the assessment of an unsealed road.

There is no charge but registration for the webinars is essential. If you can't make the live session, registration will allow Austroads to send you a link to the recording.
