Structure Comparison Tool

Given the large degree of uncertainty inherent in structural pavement design, an important element of the design process is the referencing of a design to validated benchmark pavements. These benchmark pavements are typically obtained from design catalogues or represent well validated pavements in a given climate or country. Such a validation process is invaluable in the mechanistic-empirical pavement design process, where the design outcome is highly sensitive to assumed layer stiffnesses, and where the failure criteria are often outdated or un-calibrated. By referencing the design to a validated benchmark structure, an engineer can gain confidence in the design, and determine if the design is acceptable based on established practice.

The Rubicon Toolbox Structure Comparison module is a powerful tool for comparing two pavement structures. The pavement structures are evaluated using the Monte-Carlo Simulation Model (based on Layered Elastic Theory), and results are compared in a report specifically designed for pavement comparison purposes. The Structure Comparison Tool allows engineers to compare two pavement structures based on the following aspects:

• A visual comparison of layer thicknesses and overall protection of the subgrade is done through a scaled schematic drawing;

• The locations of the expected distributions of working stresses and strains in both pavements can be compared;

• The sensitivity of working stresses and strains to layer thickness and stiffness variations can be  compared.

Key Features

• All Layered Elastic Theory (LET) modules utilize the fast and well-validated WESLEA multi-layer elastic module for stress and strain calculations;
• Ideal for evaluating pavement capacity in a relative manner when calibrated Failure Criteria (Transfer Functions) are not available;
• Allows rational comparison of working stresses and strains in two different pavement structures, including the analysis of variations in both structures;
• The Comparison Report summarizes the working strain range distribution in the two selected pavement structures;
• Neat and concise Structure Comparison Reports can be printed directly or can be exported in electronic format using simple copy and paste operations;
• Allows customization of Engineering Units to display on reports and on screen.
• Backed by MAS's efficient and personalized customer service.
