Aashto pavement design software10/30/2023 The newly AASHTO released production version of the Mechanistic-Empirical Pavement Design Guide (MEPDG) which is called AASHTOWare Pavement ME Design was developed to overcome the limitations inherent in the AASHTO 1993 method. These coefficients in addition to the seasonal variation of the roadbed resilient modulus are the only environmental consideration in the method. One of the serious limitations is the empirical drainage layer coefficients. The current flexible pavement design system in Egypt relies primarily on the 1993 American Association of State Highway and Transportation Officials (AASHTO) Design Guide. Pavements are subject to environmental conditions, which affect the performance of both flexible and rigid pavements.
