Abstract:This paper presents a simplified design procedure, which depends mainly on finite elements analysis considering the same input variables used in the traditional AASHTO empirical design methodology. The multiple regression equation developed considered the subgrade resilient modulus (Mr), Equivalent Single Axle Load (ESAL) repetitions, and the dynamic behavior of flexible pavements by incorporating vehicle speed. The outputs of this model are given in terms of structural number (SN) making it easier for the des… Show more
