AASHTOWare DARWin Product Features

product features

DARWin 3.1 includes the same powerful features as previous versions of the program, as well as many enhancements and new features. Some of the major enhancements to DARWin 3.1 are as follows:

Operating Systems
DARWin 3.1 has been designed to be run under Microsoft Windows 95, 98, and NT operating systems. Because DARWin operates in the Windows environment, design engineers can perform pavement design operations and use other compatible software, such as spreadsheets and word processors, simultaneously.

Metric Conversion
DARWin 3.1 performs on-the-fly conversion between metric and English units. Users can enter data and display output in either unit system. By simply clicking the mouse, DARWin will automatically convert all inputs and outputs to the selected unit system.

Project File Management
This approach allows flexible pavement designs, rigid pavement designs, overlay designs, and life cycle cost analyses to be stored in a single compound file. In addition, a DARWin project file can store files from other software (spreadsheets, document files), allowing all relevant information to be compiled into a single project file.

Combined Material & Pay-Item Library

DARWin 3.1 combines the material and pay-item libraries into one Open Data Base Connectivity (ODBC) compliant library. The new library features two hierarchical levels for categorizing and sorting information stored in the library. This library allows storing pay-item cost and material property information in both metric and English units and will also allow user-defined pay-item units.

Deflection Data & Processing Analysis

DARWin 3.1 allows processing multiple deflection data files for one project and provides the ability to filter deflection data based on load range, test type, sensor configuration, and test location. On the analysis side, point-by-point backcalculation and load transfer calculation results can be obtained by entering deflection data manually or by importing deflection data files.

Graphical Output

A number of graphical features have been added or improved in DARWin 3.1. Additional graphics include project cash flow diagrams in the Life Cycle Cost module and pavement deflection profiles in the Overlay Design module.
