Mechanistic Pavement Design - CIRCLY

This one day course focusing on flexible pavements is ideal for engineers and engineering technologists working for federal, state, or local authorities, consultants and contractors who have an awareness and understanding of the basic principles & practices of pavement design.



NEW ERA in Pavement Design has come to Australia with the release of the 2017 edition of the, Austroads Guide to Pavement Technology: Part 2: Pavement Structural Design. The most extensive update to the Guide in more than a decade has significantly changed the way in which designers develop next generation pavement engineering solutions. Changes to the Guide have been incorporated into various CPEE Short Courses. Don't miss this chance to enhance your knowledge and skills!

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 loaded with the CIRCLY program.

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 Flexible Pavement Design courses, or for those who have, or are attending any of the con- current “Flexible Pavement Design – Principles & Practice” 2-day course.

The CIRCLY Pavement Design software is the core of the flexible pavement design methodology defined by the AUSTROADS Guide to Pavement Technology– Part 2: Pavement Structural Design (the Guide) is regarded as a primary reference source. CIRCLY is a proven design tool used over the past two decades in thousands of design applications world-wide. CIRCLY aids those involved in designing, constructing and using pavements.

CIRCLY 7.0 allows a major advancement in pavement design: a fully integrated system with superior design power & ease of use. CIRCLY 7.0 has many time saving features such as an automatic thickness design capability that can save hours on a typical design job. A Parametric Analysis feature can loop through a range of thicknesses for one or two layers, while simultaneously designing the thickness of another layer. This feature will optimise up to three layers. Combining this with a Cost Analysis feature, allows for fine-tuning of layer thicknesses to minimise construction and maintenance costs.
