The general theory of stresses and displacements in layered soil systems. Application des potentiels à l’étude de l’équilibre et du mouvement des solides élastiques: principalement au calcul des déformations et des pressions que produisent, dans ces solides, des efforts quelconques exercés sur une petite partie de leur surface ou de leur intérieur: mémoire suivi de notes étendues sur divers points de physique, mathematique et d’analyse (Vol. Finally, the equivalent resilient modulus obtained by nonlinear analysis can be used to calculate mechanical responses of pavement structure except the surface deflection in a linear analysis.īitumen Business Group (1998). Additionally, the use of diverse nonlinear analysis methods has different levels of impact on mechanical responses. In contrast, the theory of the elastic layered system only considers the dependence of the resilient modulus on the stress in the depth direction. Besides, the Finite Element Method could consider the variation of the resilient modulus induced by the change in the stress condition in both the radial and the depth directions simultaneously. The results show that the difference among the nonlinear analysis algorithms used by the two software packages is mainly reflected in the determination of the initial resilient modulus, the stress correction, and the convergence condition. Moreover, the feasibility of the equivalent resilient modulus obtained by the Finite Element Method is discussed. Furthermore, by conducting a case study, the impact of using different analysis methods on the calculation results is presented. Two representative programs, MICH-PAVE and KENLAYER, are selected and compared to many key aspects of their analysis algorithms to achieve an in-depth understanding of the features of the Finite Element Method and elastic layered system theory in nonlinear material analysis of the structure of asphalt pavement.
