MEPDG provides a rational pavement design framework based on the mechanistic-empirical principlesto characterize the impacts of traffi c, climate, and material properties on the pavement performance. Before replacingthe 1993 Pavement Design Guide (and its accompanying DARWin 3.1 design software) currently used by LouisianaDepartment of Transportation and Development (LADOTD), the nationally calibrated MEPDG design models need to befurther validated and calibrated against the local conditions in Louisiana
