CIRCLY is the leading pavement design software for roads and highways. CIRCLY implements a rigorous flexible mechanistic pavement design methodology that incorporates state-of-the-art pavement material properties and performance models. CIRCLY is an integral component of the AUSTROADS Australian Pavement Design Guide.

Easy to use, yet comprehensive

• The user-friendly menu driven interface runs under Microsoft Windows.

  Most functions are accessible from the toolbar:

• typical runs take a few seconds on Pentium PC's

• pavement and loading databases eliminate need to constantly re-key information.

• results in tabular form and report quality graphs.
• Sample plot of lateral distribution of cumulative damage predicted by CIRCLY
• report quality hard copies can be made on the wide range of printers and plotters supported by Microsoft Windows.
• results can be easily exported to other application packages such as spreadsheets for further processing.

Material models

• multi-layered pavement system
• isotropic and anisotropic materials
• wide range of performance criteria includes all popular models
• define your own criteria
• automatic sub-layer generation for granular materials.

Traffic

• no limit on the number of vehicle types or loading conditions
• analysis explicitly uses specified spectrum
• erroneous short-cuts such as "equivalent" axles are not necessary
• special loadings such as braking included

Proven Technology

This Australian designed system has been developed by Melbourne company MINCAD Systems. It has been in regular use in Australia and World-wide for more than two decades proving its worth in thousands of design applications. Since 1987 it has formed an integral part of the Austroads Pavement Design Guide which has recently been adopted by Transit New Zealand for use in New Zealand.

Benefits from CIRCLY

CIRCLY offers benefits to all parties involved in designing, constructing, owning and using pavements.

• Designers benefit from the inclusion of automated functions and faster analyses.
• Material suppliers will make significant saving because the costs and dangers of over-specification or under-specification due to inaccurate information are significantly reduced.
• The facility owner benefits from more efficient use of materials and will reap long term benefits because changing traffic patterns on proposed designs can be considered and planned for.
• The community will benefit from increased efficiency and effectiveness in building this essential infrastructure.

System Requirements

• Hardware:
  486DX or Pentium-based PC.
  8 Mb RAM
• Software:
  Microsoft Windows 3.1 or later and Microsoft Excel for Windows 5.0 or later.
