Análise Quasi-estática e dinâmica de pavimentos asfálticos.

Abstract

The present paper discusses the importance of using dynamic analyses to provide a better understanding of the structural response of asphaltic pavements. To this end, the Newmark’s algorithm was implemented for linear elastic and viscoelastic constitutive models in a Finite Element system. Quasi-static and dynamic analyses using different pulse loads where carried out in order to evaluate the differences in the structural responses generally used in mechanistic pavement design: (i) displacement on top of the asphalt surface layer; (ii) tension stress at the bottom of asphalt surface layer and (iii) compression stress on the top of the subgrade.
