Avaliação estrutural e retroanálise de um trecho de pavimento da avenida Tiarajú no município de Alegrete – RS com a utilização de viga Benkelman

Abstract

This work has as main objective to use the Benkelman beam equipment for the deflectometric survey and evaluation of the deformations of a stretch of flexible pavement of Tiarajú Avenue in the urban area of the city of Alegrete. Allow a structural evaluation through back-analysis using the BackMeDiNa program and obtain the possible values of resilience modules of all points and layers of the stretch in the study. Estimate the design life of the pavement constructed from the evaluation of the structure through the program MeDiNa, finding results about the permanent deformations and area of cracking of the points, thus determining, its influence in the design of a possible reinforcement in the constructed pavement. It was possible to observe that in the section under study several values of deflections and varied values of Resilience Modules were obtained, these different situations result in different project lives. Possibly these very different results are results of the lack of control during the stage of road construction.
