Análise do comportamento estrutural de pavimentos rodoviários e urbanos construídos na região de Santa Maria

Abstract

In this work, it was analyzed, under the light of the resistance and resilience, the structural behavior of the pavements of Santa Maria Contour, BR-158, executed in 1971 and 1973 and the executed reinforcements in 1977 and 2001 and compared to other structures of road pavements constructed in the region of Santa Maria in the last 30 years. Also, it was studied the structural behaviors of the urban pavements of Santa Maria with different structures, through deflectometric surveys before and after the reinforcements of the existing pavements with hot planted bituminous concrete. This measurements permitted to separate the group of studied streets in distinct groups according to their pavement structure. All them present reduction of the elastic deformation, in viable degrees, but increasing, according to the variation of the existing covering, of the hot planted bituminous concrete. The measures of the elastic deformations will be great worth for adequate management of them, because they express very well the elastic behavior of the several structures of urban pavements, permitting global and punctual analysis for the elaboration of recommendations, procedures and sizing.
