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.

Description

Overview:

Pavement design in Australia has entered a new era 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 will significantly change the way in which designers develop next generation pavement engineering solutions. The new Guide was released in December 2017.

This workshop will emphasise CIRCLY 7.0's implementation of the significant changes to the 2017 Austroads Guide.

The most significant 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.

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 con-current "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 is a major advancement in pavement design: a fully integrated system with superior design power & ease of use. CIRCLY 7 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.
