Note: The CIRCLY Workshop is a "hands-on" experience with each student having their own PC - so 16 places only.
These courses are recognised by Engineers Australia for Continuing Professional Development (CPD) purposes.
Registration forms and other details will be available approximately 4 weeks prior to the courses.

Support for Windows Vista
Mincad Systems is pleased to announce our commitment to Windows Vista by supporting this new operating system. Windows Vista is a step forward toward increasing the security of Windows.
The following packages fully support Windows Vista:
The latest version of CIRCLY 5.0 is Version 5.0m (4 June 2008).
The latest version of APSDS is 4.0k (26 September 2006).
The latest version of HIPAVE is 5.0i (3 October 2007).
New software for intermodal container terminals
HIPAVE (Heavy Industrial PAVEment design) is for the mechanistic analysis and design of flexible pavements subjected to the extremely heavy wheel loads associated with freight handling vehicles in industrial facilities, in particular, intermodal container terminals. It is designed to conveniently model each combination of vehicle model and container load and to combine the damage using the Cumulative Damage Factor concept.

A Powerful Tool for Pavement Cost Optimization
Automatically generated plot: Total Cost vs. Layer 2 Thickness
The CIRCLY 5 Cost Analysis feature lets you fine tune layer thicknesses to minimize construction cost. You can specify unit costs for each material.
CIRCLY 5 has a Parametric Analysis feature that will loop through a range of thicknesses for one or two layers, while simultaneously designing the thickness of another layer.
Click here for a Preview of the Cost Analysis feature.
Support for Austroads 2004 Pavement Design Guide
A draft of the revised Austroads Pavement Design Guide was published in 2001. Work on the new Guide is in the final stages and is expected to be released in mid-2004. The 2001 revision of the Austroads Pavement Design Guide has been issued as a final draft for evaluation end comment from users prior to formal publication by Austroads in 2004.
Further details and how to order the Current or 2001 Draft of the Guide
CIRCLY 5 includes new important features to support the 2004 revision of the Guide:
- New Sub-Layering method for Granular Materials
- Use of Reliability Factors
Warning: Neither CIRCLY 3.0 or CIRCLY 4.0 can automatically handle the Austroads 2004 sub-layering.
Recorded Demonstrations
We now have a number of online recorded demonstrations of the new CIRCLY 5.0 features.
Discussion Forum for News and Technical Talk
See our new Discussion Forum.
We have created a ‘Bulletin Board’-style Forum for News and Technical Talk. Drop by and have a look. In the Technical Talk category, the section ‘Roads (Austroads Pavement Design Guide)’ will prove to be a particularly useful resource when the new version of the Guide is published.
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 provide 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.
New Paper on Current Issues for Mechanistic Pavement Design
- Wardle, L.J., Youdale, G. and Rodway, B. (2003). Current Issues For Mechanistic Pavement Design. in 21st ARRB and 11th REAAA Conference, Cairns, Australia, 18 - 23 May, 2003, Session S32, ARRB Transport Research.
This paper discusses four issues currently faced by designers using mechanistic software such as CIRCLY and APSDS to produce pavement designs that are consistent and appropriate. The issues are:
- the choice of appropriate failure criteria
- the treatment of vehicle wander
- negative vertical subgrade strains that can lead to anomalous design results for some pavement geometries
- design of asphalt-surfaced granular pavements,
The first three issues primarily impact the design of heavy duty pavements. The last issue relates to proposed changes to the Austroads (1992) Pavement Design Guide as published in the 2001 Draft Guide (Austroads, 2001).

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.

U.S. Airport Pavement Researchers to use APSDS and CIRCLY
APSDS and CIRCLY have just been licenced to the U.S. Center of Excellence for Airport Pavement Research at the University of Illinois (Urbana-Champaign). The Centre is supported by the Federal Aviation Administration, with the aim of developing pavement design for next generation aircraft. APSDS and CIRCLY will be used to analyse results from the US Airport Pavement Testing Facility, the newly commissioned accelerated full-scale pavement loading machine.CIRCLY chosen by U.S. Researchers for modelling Unbound Aggregates
The International Center for Aggregates Research (ICAR) is the voice of the U.S. aggregates industry in the research community.
Under the direction of Professor Robert Lytton, the ICAR team has developed models that explain the anisotropic properties of the unbound aggregate system. This work demonstrates the stress sensitivity and anisotropic nature of Poisson ’s ratio and how critically important it is to measure the anisotropic and stress-sensitive response of Poisson ’s ratio properly. The team has recently adopted CIRCLY as the basis for implementing the new aggregate model in a pavement design framework.
Important Warning- Heavy Duty Pavements
It has been acknowledged that 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 Rodway and Wardle (1998).
Using CIRCLY with the Austroads Pavement Design Guide
The Austroads Pavement Design Guide is the basis for road pavement design in Australia and New Zealand.
The Design Guide has been undergoing a major re-write which is expected to be published in late 2003. Much of the material is in draft form. The revised mechanistic design procedure requires that CIRCLY 3.0 or later be used. CIRCLY 3.0 introduced an enhanced calculation engine for improved accuracy and faster results. Current CIRCLY 2.0 users are advised to upgrade to Version 5.0, as results may be inaccurate in some cases.
We now have a separate page covering important news for using CIRCLY with the AUSTROADS Pavement Design Guide. This details important changes to the Guide issued since it was first published and how this affects CIRCLY.
A few clicks will keep your copy of CIRCLY up to date.
CIRCLY 5 lets you to check for a newer version on our website just by clicking Help/From the Web/Check for Updates. To download the latest update click here.
Layered Elastic Pavement Design- Recent Developments
We have recently published a paper that gives an overview of mechanistic pavement design and recent developments in CIRCLY 4.0. For further details see Wardle and Rodway (1998).
