Influência da resistência à compressão e da espessura dos blocos de concreto e as espessuras das juntas na deformação permanente dos pavimentos em blocos intertravados

Abstract

Permanent deformation is the main factor of mechanistic verification of concrete block pavements with granular layers. Thus, this article aims to evaluate the influence of the variation in the compressive strength, the thickness of the blocks of concrete and the condition of the joints between the blocks depending on the spacing. The evaluation was carried out through an elastic analysis and subsequent applications of models of plastic behavior of each material. The condition of the joints proved to be the most sensitive parameter in the performance of the structure to permanent deformation, while the compressive strength of the blocks didn't show much difference in the plastic behavior due to the variation of this parameter. In addition, it was found that the increase in the thickness of the parts provided an improvement in performance to permanent deformation, but the sensitivity of this parameter was much less than the alternations of the joints.
