Trusted Design Software Receives Major Upgrade
Flexible Pavement Design Example
SpectraPave software provides pavement design engineers the most powerful tool available for evaluating roadway design options and optimizing pavement performance using Tensar Geogrids. This free program specializes in the optimization of paved roadways as well as the stabilization of unpaved roadways and construction platforms.
Since 1987 it has been part of the Austroads Pavement Design Guide, the standard for road design in Australia and New Zealand. CIRCLY 7.0 uses a rigorous flexible pavement design approach. It uses state-of-the-art pavement material properties and performance models. It calculates the cumulative damage induced by the traffic spectrum.
This comprehensive, systems-based design software suite offers the full benefits of Tensar's knowledge and experience in analyzing both subgrade stabilization and pavement optimization applications. These applications incorporate the entire range of Tensar TriAx geogrids.
SpectraPave enable users to:
While it is recommended for users to view the training module video above prior to download and installation, no previous knowledge or experience in pavement design is required to benefit from using the software.
What changed with the recent update?
The updated Pavement Optimization module is intended to help engineers, public agencies, owners, and contractors better understand the true value of using TriAx geogrids in their pavement sections. That value can be determined by examining pavement life extension, reduction of initial construction time and cost, reduction of life cycle costs, reduction of fuel and water consumption during construction, just to name a few.

CIRCLY 7.0 is a powerful, user-friendly, Windows-based package for mechanistic pavement design and analysis.
This Australian designed system has been in regular use World-wide for more than two decades proving its worth in thousands of design applications.

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.

Pavement and loading databases save re-keying information. You can define your own material properties and loadings.
Viewing the Results
CIRCLY 7.0 generates graphs that show the damage factor across the pavement. CIRCLY 7.0 can also generate graphs of any component of displacement, strain or stress in two-dimensional or three-dimensional form.

Automatic Thickness Design capability – determine the optimum thickness of a given layer in a fraction of a second on any PC.
Simultaneous calculation of the damage factor for all layers with a performance model.
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. The Cost Analysis feature lets you fine-tune layer thicknesses to lower construction and maintenance costs.

System Requirements
Alternative design systems for Heavy Duty Pavements
A special design system, APSDS (Airport Pavement Structural Design System) is for airport pavements. It is based on the CIRCLY system and has been enhanced for design of airport pavements.
HIPAVE (Heavy Industrial PAVEment design) is software for design of flexible pavements in facilities such as intermodal container terminals and yards. HIPAVE models the extremely heavy loads from vehicles such as mast lifts, reach stackers, straddle carriers etc.

We recently published an article that explains why road design methods are not appropriate for the heavy loadings at airports and container terminals. Road design methods can give grossly under-designed pavements.
