• Abstract:
  The need for developing a method to account for variations and uncertainties of factors in pavement design was recognized by the FHWA-HRB Advisory Committee of the "Workshop on the Structural Design of Asphalt-Concrete Pavement Systems" in 1970 as one of the most pressing problems facing pavement engineers. A first step in the solution of the problem was taken when stochastic design concepts were applied to the Texas Flexible Pavement Design System (FPS). The probabilistic approach makes it possible to design for a desired level of reliability through consideration of the variabilities and uncertainties associated with pavement input variables. In order to utilize this added feature of FPS, estimates of the variations associated with the various input parameters, and the lack-of-fit error of the empirical models used in the system have to be determined.
