Flexible Pavement Design System Fps 19w

FPS 19W is the approved flexible pavement thickness design system used by the Texas Department of Transportation (TxDOT). Project 0-1869 made several enhancements to this system, including: a) transferring the system to the Windows® platform, b) automating the Texas Triaxial system to provide a thickness checking system, c) incorporating stress and strain computational subsystem so that classical fatigue and rutting lives can be estimated for the designed pavement, and d) incorporating an extensive on-line help system. In this project the models within FPS 19W were further calibrated. New approaches were also incorporated for handling designs on pavements with very thick flexible bases.
