  • Abstract:
    The current flexible pavement design system (FPS) ; used at the Texas Department of Transportation ; (TxDOT) has limitations in that it does not use any ; results from laboratory testing, so it is impossible to ; determine benefits from improved base materials or ; superior asphalt mixes. Developments over the last ; several decades have offered an opportunity for more ; rational and rigorous pavement design procedures. ; Substantial work has already been completed in ; Texas, nationally, and internationally in all aspects of ; modeling, materials characterization, and structural ; design. These and other assets provided the technical ; infrastructure that made it possible to develop a new ; mechanistic-empirical flexible pavement design ; system (TxME) specifically for Texas. This new ; system will enable Texas pavement designers to take ; full advantage of new or premium materials, with a ; full consideration of the influential factors, including ; pavement structure, traffic volume, and environmental conditions. ; The main objectives of this project were to identify or ; propose performance models and implementation ; approaches, and develop the new TxME.
