The Austroads Pavement Structural Design Guide is the basis for road pavement design in Australia and New Zealand.
CIRCLY 7.0 gives Reduced Asphalt Thickness for Heavy-Duty Structures
The following graph illustrates the considerable reduction in Asphalt thickness for pavements at higher traffic loads designed with CIRCLY 7.0 (using the Austroads 2017 Design Method), compared to CIRCLY 6.0 (using the Austroads 2004-12 Design Method).
This leads to reduced material and construction costs.

CIRCLY 7.0 RELEASED!
CIRCLY 7.0 has just been released.
You can get an Overview of CIRCLY 7.0 by starting here.
Then click the Next > button at the bottom right hand corner on each page.
The Austroads Pavement Structural Design Guide has undergone a major revision that was released in December 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 – at no extra cost if you have a current CIRCLY Annual Subscription.
2017 Austroads Pavement Structural Design Guide Released
Austroads Guide to Pavement Technology – Part 2: Pavement Structural Design (AGPT02-17) was released in December 2017.
2011 Austroads Pavement Evaluation and Treatment Design Guide Released
AGPT05-11 : Guide to Pavement Technology – Part 5: Pavement Evaluation and Treatment Design was released in December 2011.
This publication is an update of AGPT05-09. It contains an inclusion of thickness design for stabilisation treatments, and has also been reformatted which includes realigning the contents page and the lay out to make the information more accessible for the reader.

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.
