This document provides a userŅs guide to the LoadGage program. LoadGage is a computer program for checking flexible pavement designs that incorporates improvements to the modified triaxial design method currently implemented by the Texas Department of Transportation (TxDOT). These improvements are based on the findings from Project 0-4519, during which researchers verified the triaxial design method and characterized the variations of climatic and soil conditions between the different counties of the state. The userŅs guide describes the main menu, running an evaluation and viewing output, defining the subgrade failure envelope, the nonlinear analysis option, and an example program application. The appendix describes the calculation of the Mohr-Coulomb yield function.
