Cloud-based Pavement Design Software

Rubicon Toolbox is a suite of Online Tools that can greatly increase the productivity of engineers involved with pavement rehabilitation design. Routine analyses such as mechanistic-empirical pavement design calculations, analysing DCP data and summarizing and processing of Trial Pit data are catered for in the user friendly software. Advanced tools such as Axle Spectrum and Finite Element Analyses can enhance the depth and scope of pavement analysis and design calculations.

Online Tools Window

The Online Tools window shows all the saved analyses, and the various Tools are launched from the icons on the left side.

Design Tools: Standard Axle

Analyzes pavement response and calculates expected structural capacity under a user-defined axle load using multi-layered elastic theory. This process is often referred to as Mechanistic-Empirical pavement design. The materials and criteria used in the South African Mechanistic-Empirical Design Method are included, as are some other well-known and widely used failure criteria (transfer functions). New criteria can be included by user request. The Tool accommodates up to 6 layers.

Design Tools: Axle Spectrum Tool

Evaluates the impact of an axle load spectrum on a pavement’s design capacity. An axle load spectrum can be built and analysed for a specific design situation. The axle spectrum can consist of any number of axle types. The Tool can accommodate up to 6 layers.

Design Tools: Pavement Number

Determines the pavement life using the easy-to-use Pavement Number structural design method. The Pavement Number is a modified Structural Number and was developed with data from real pavement structures. Both the 2009 and 2020 Pavement Number versions are available.

Design Tools: DEMAC Material Classification

The Design Equivalent Material Classification (DEMAC) determines the certainty that a material is equivalent to a new material of the same class for design purposes. Classes derived using this system represent the condition in the field that may differ from a pure laboratory classification due to the inclusion of parameters such as in situ density, backcalculated stiffness, and DCP penetration rate amongst others. The classes are based on the South African material classification system. Both the 2009 and 2020 DEMAC versions are available.

Design Tools: AASHTO 1986

Evaluates the structural capacity of a pavement using the empirical AASHTO 1986 (Structural Number) design method. Although this method is old, it can still serve as a valuable extra check to compare your pavement structure to accepted norms.

Stripmap

Our flagship tool for graphical display and synthesis of numerical, text and engineering data, such as rutting and roughness data and visual assessment data. The stripmap is setup in an easy-to-use Excel template. The user has control over what data to include, how to present the data and the colour interpretations.

Manual Backcalculation

In-depth analysis of deflection bowls measured with a Falling Weight Deflectometer or Benkelman Beam. The user inputs the stiffnesses used for the backcalculation.

Manual_Backcalculation

Automated Backcalculation

Automated backcalculation of layer stiffnesses from Falling Weight Deflectometer (FWD) data. Incorporates built-in reporting and statistical analysis features and summaries in tabular and graphical format. The results can also be exported to Excel for further analyses, including incorporation into a stripmap using the Stripmap Tool.

DCP Analysis Tool

Efficient analysis and summary of Dynamic Cone Penetrometer test data. Data are viewed in Single View, one DCP point at a time, or several DCP points can be viewed together in the Multiple View. DCP data can be analysed to determine layer thicknesses, penetration rates per defined layer, and DCP derived CBR and stiffness values. The layer strength diagram is used to determine the adequacy of a pavement for a required capacity. A summary of the DCP parameters can be exported to an Excel spreadsheet for further analyses.

DCP_Analysis_Tool

Trial Pit Report (Reporting Tools)

Efficient storage and documenting of Trial Pit investigation data. A summary view provides a useful overview of the trial pit profiles.

Trial_Pit_Report

Grading Evaluation Tool (Reporting Tools)

Quickly analyzes the particle size distribution (grading) of a material. The Grading Evaluation Tool plots a measured material grading with a selected grading envelope, which typically represents a material specification. A summary of many gradings can also be viewed together, with a grading specification envelope.

Clients Feedback

Rubicon gives me a great sense of confidence when using it as design software. We benchmark our major pavement designs within an international group of practitioners using a range of software, and Rubicon is seen as the de-facto reference standard. - Dr Stephen Emery (Kubu Australia Pty Ltd)
I use the pavement analysis tools extensively for rehabilitation projects and have yet to come across a scenario that cannot be managed quickly and efficiently with this software, especially when it comes to dealing with load set-ups for something out of the ordinary. - Dave Collings (Member, UCD Technology/Loudon International)
The most wonderful thing about Rubicon Toolbox, as the name suggests, is the holistic approach to Pavement Engineering. A toolbox that allows me to analyse various forms of pavement data, run pavement designs, and present all findings on a single stripmap. The software is simply a dream for a Pavement Engineer. - Tumelo Thothela (Aurecon Group)
Software packages are an essential part of being successful as a consulting engineer. When it comes to road pavement engineering, we at KBK Engineers exclusively make use of the Rubicon Suite of programs to do all our design and assessment work. We have scanned the market and in our opinion one has to look no further. - N.J.J. Jooste (KBK Engineers (Pty) Ltd)
Rubicon has clearly been designed by practitioners who use it in consulting practice. It is very powerful and can rapidly handle multiple sets of input data, but is still easy enough to use. It is oriented to the consulting engineer, with outputs that are clear, great graphics, and excellent for direct use in reports. - Dr Stephen Emery (Kubu Australia Pty Ltd)
