Austroads Pavement Design Guide

The Austroads Pavement Structural Design Guide is the basis for road pavement design in Australia and New Zealand.

CIRCLY 7.0 – implementing the 2017 Austroads Pavement Structural Design Guide – Coming Soon

The Austroads Pavement Structural Design Guide is undergoing a major revision that is expected to be released in mid-2017.

The major change is how the details of the Traffic Load Distribution (TLD) are used as design inputs. The Traffic Load Distribution consists of the frequency distribution of Axle Group Loads.

Here’s an example of CIRCLY 7.0‘s Traffic Load Distribution screen:

You can upgrade to CIRCLY 7.0 when it is released – at no extra cost if you have a current CIRCLY Annual Subscription.

2012 Austroads Pavement Structural Design Guide Released

Austroads Guide to Pavement Technology – Part 2: Pavement Structural Design (AGPT02-12) was released in February 2012.

Important Warning- Heavy Duty Pavements

Performance data developed for highway pavements (e.g. Austroads) is not generally appropriate for heavy loadings such as airports and container terminals.   Use of such models can lead to grossly under-designed pavements.

For further details see the Heavy Duty Industrial Pavement Design Guide.
