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.
Haul Road Design website launched!
We have just launched the Haul Road Design website – a rich resource for Articles, Papers, Reports and Software for Mine Haul Road Design.
CIRCLY 6.0 Tutorials Launched!
We are pleased to announce that the CIRCLY 6.0 Tutorials are online.
CIRCLY 6.0 now available
CIRCLY 6.0 has just been released.
CIRCLY 6.0 includes a new user interface that makes it easier and faster to set up analyses.
We recently ran 3 CIRCLY 6.0 workshops with 14 – 21 students.
We were able to slice 30 slides from the Powerpoint presentation because of the simpler inputs.
We estimate it took 30-45 minutes off the time it took the students to do the exercises.
There was very positive feedback about the new interface.
You can get an Overview of CIRCLY 6.0 by starting here.
Then click the Next > button at the bottom right hand corner on each page.
CIRCLY 6.0 will run on Windows 7, 8.x and 10. CIRCLY 5.0 will not run on Windows 8.x. CIRCLY 5.1 and CIRCLY 6.0, are compatible with Windows 8 and older systems such as Windows 7.
Convert your CIRCLY 5.x data to CIRCLY 6.0
We now have the CIRCLY 5.x to CIRCLY 6.0 Data Converter.
It will convert all of your CIRCLY 5.x data to CIRCLY 6.0.
Please contact Mincad Systems for more details.

CIRCLY, APSDS and HIPAVE Workshops – 2017
The Centre for Pavement Engineering Education (CPEE) will be presenting the following Short Courses/Workshops this year:
Mechanistic Pavement Design – CIRCLY
This one day course provides delegates with an understanding of the theoretical basis of mechanistic pavement design methods and is a hands-on course with each student having access to a PC. The course is offered as a single day for those who are well versed and practiced in pavement design, or who have completed any of the past CPEE two day Pavement Design courses, or for those who are attending the current Pavement Design – Principles & Practice 2 day course in 2017.
The course provides an introduction to flexible pavement design models using CIRCLY 6.0 focusing on the Austroads Guide to Pavement Technology – Part 2: Pavement Structural Design (AGPT02-12).
The workshop will also include an introduction to heavy duty pavement design for container terminals and airports.
Heavy Duty Pavement Design Workshop (HIPAVE / APSDS) <<< to be scheduled for 2017 – Register your details below >>>
This one day course focuses on computer aided design of heavy duty flexible pavements using HIPAVE and APSDS (Airport Pavement Structural Design System).The emphasis is on pavements subjected to the extremely heavy wheel loads associated with airports and freight handling vehicles in industrial facilities, such as intermodal container terminals. This is a hands-on workshop with each student having their own PC.
These courses are recognized by Engineers Australia for Continuing Professional Development (CPD) purposes.

CIRCLY 5.0 Maintenance and Support discontinued
CIRCLY 5.0 Maintenance and Support was discontinued on 1 November 2012. The impact of this date depends on what type of CIRCLY Licence you have:
CIRCLY Annual Licence
If you have a CIRCLY Annual Licence:
You should upgrade to CIRCLY 5.1 or CIRCLY 6.0 (at no charge) as this will make sure that you have the most up to date version of the program.
To upgrade to CIRCLY 6.0 contact Mincad Systems.
To upgrade to CIRCLY 5.1:
Download the CIRCLY 5.1 installer from here.
Remember that if you intend to use Windows 8.1 or Windows 10, that you must install CIRCLY 5.1 or CIRCLY 6.0 (CIRCLY 5.0 cannot be used).
CIRCLY 5.0 Perpetual Licence
If you have a CIRCLY 5.0 Perpetual Licence:
A CIRCLY 5.0 Perpetual Licence allows you to use CIRCLY 5.0 for as long as you want. CIRCLY 5.0 will continue to run on any versions of Windows before Windows 8.
CIRCLY 5.0 will no longer be maintained or supported from 1 November 2012.
You will need to order a CIRCLY Annual Licence to keep receiving maintenance and support (or to use Windows 8 or any future version of Windows). You pay in advance for an Annual Licence. There are no further charges for support and maintenance and you receive major upgrades such as CIRCLY 6.0. The Annual Licence price may increase in future years in line with list prices.
Replacement CIRCLY 5.0 Hardware Locks
Please note: We will continue to replace any CIRCLY 5.0 Hardware Locks at the standard replacement charge (now $475 incl. GST and delivery) for an indefinite period.
RTA Supplement to Austroads Guide to Pavement Technology Released

CIRCLY and Mechanistic Pavement Design: The Past, Present and Towards the Future
It has been about 30 years since CSIRO released CIRCLY, originally a FORTRAN program for analyzing Layered Elastic Media subject to surface loads. This paper (CIRCLY and Mechanistic Pavement Design: The Past, Present and Towards the Future – Leigh Wardle (2010)) gives an overview of how CIRCLY has evolved – from the first mainframe version, to the current user-friendly Windows-based, version 6.0 as the standard pavement design package used in 35 countries. CIRCLY has closely tracked the Austroads mechanistic flexible pavement design procedure as it has developed.
2012 Austroads Pavement Structural Design Guide Released
Austroads Guide to Pavement Technology – Part 2: Pavement Structural Design (AGPT02-12) was released in February 2012.
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 covers thickness design for stabilisation treatments.
We now have a number of online recorded demonstrations of the new CIRCLY 5.0 features.
Sample Pavement Design Report (by Graham Foley)
As a service to our clients we are making available a Sample Pavement Design Report written by a specialist pavement engineer, Graham Foley. This report is an example of using the general mechanistic procedure to refine an existing pavement design to give an alternative pavement design. It will be of use to both experienced and less-experienced pavement designers as how to approach and document a mechanistic design.

CIRCLY receives high rating in European Pavement Design Study
Research by the European Economic Community has identified that a standardised European pavement design and maintenance strategy will lead to savings of billions of dollars in construction and maintenance costs. The first step in this standardisation process, the AMADEUS (Advanced Models for Analytical Design of European Pavement Structures) Project, a coordinated European Road Research Program formally commenced in January 1998.
The AMADEUS Project involved a team of 15 national partners (Great Britain, Germany, The Netherlands, Belgium, Portugal, Denmark, Austria, Spain, Greece, Sweden, Finland, Switzerland, Iceland, Slovenia, Hungary) and included national highway research institutions, universities and other road research organisations. The project reviewed current pavement design methods and software. CIRCLY was one of the few packages that was capable of being used in all the phases of the project and achieved good ratings in all categories.
