  • 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.
