Monte Carlo Pavement Response Simulation

Rubicon Toolbox incorporates several tools that utilize the layered elastic theory (LET) model for pavement response calculation. The LET: Monte Carlo Pavement Response Simulation tool allows users to evaluate the impact of variations in pavement layer thickness and stiffness, as well as variations in load wander, on calculated pavement responses. For each layer, a different distribution of stiffness and thickness can be specified. Rubicon Toolbox uses an advanced distribution simulator which can simulate normal as well as skewed distributions. Users can also specify limits for the distribution, to ensure that these limits will not be exceeded during the simulation.

Once the load and layer property variations have been defined, the impact of these variations on stresses and strains in the pavement can be evaluated. Using the Monte Carlo simulation technique, a distribution of response values is calculated for each design parameter (e.g. horizontal tensile strain at the bottom of the asphalt surfacing). This distribution can then be analyzed in detail to obtain an indication of the risk associated with a specific layer or pavement situation. The Monte Carlo simulation module is also useful for evaluating the sensitivity of a particular design to a variations in layer thickness and stiffness.

The LET: Monte Carlo Pavement Response Simulation tool has several built-in features that allow users to analyze the generated response distributions. Users can select a reliability level and instantly display the design parameters associated with the chosen reliability level. As with all MAS software, a "black box" impression is avoided by allowing users to view and analyze all simulations. All of the simulated pavements in the distribution can also be exported to Microsoft Excel, from where in-depth analyses can be performed, and from where graphical summaries of the results can be generated.
