Geotechnical investigation and design guidance updated
20 May 2019
Austroads has released an updated edition of
Guide to Road Design Part 2: Design Considerations with a new extensive
section on
geotechnical investigation and design.
Guide to Road Design Part 2 provides a detailed description of design
objectives, context-sensitive design, and factors that influence road
design such as Safe System philosophy.
The new appendix describes the importance of geotechnical investigations
and the way
road design outcomes are influenced by site conditions,
associated ground response, geological hazards and locally available
material.
The content in the appendix replaces Guide to Road Design Part 7 which
has been obsoleted. Updates to the appendix include:
-
expanded information on aims of a geotechnical investigation and design, desktop assessment, approvals for site investigations and design elements
-
new sections on safety during investigations and observational method. References to Austroads Guides have been updated throughout.
The 2019 edition of Guide to Road Design Part 2 as written by David
McTiernan, Ganesh Vengadasalem, Peter Ellis, Robert Grove and Peter
Aumann. The update project was managed by Peter Ellis,
Roads and Maritime Services
NSW.
The PDF version of the Guide is available to download for free and the
updates have been incorporated into the online version of the Guide.
