摘要: |
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 research and development efforts conducted in that project are documented in two companion reports by Fernando, Oh, Estakhri, and Nazarian (2007) and by Fernando, Oh, Ryu, and Nazarian (2007). The interested reader is referred to these reports for details on the work conducted during the project to review and understand the original development of the load-thickness design curves, to verify these curves from laboratory and field test data, and to improve the existing design method based on the project findings. The document provides a user's guide to the LoadGage program. / Supplementary Notes: See also PB2008-111673 and PB2009-103204.
