Avaliação estrutural do pavimento asfáltico das vias internas da cidade universitária Paulo VI da Universidade Estadual do Maranhão utilizando a viga Benkelman

Abstract

In Brazil, road transport has for years been the main choice for transportation of people and products, as well as being the main responsible for the integration of the entire transportation system, contributing significantly to the socioeconomic development of the country. The intense traffic, climate, construction methods and physical characteristics of the materials used in the construction of pavements can cause functional and structural changes in them, such as reversible and permanent deformations. Objective with this work is to evaluate the structural condition of the asphaltic pavement of the Paulo VI university city of the State University of Maranhão (UEMA), using the Benkelman beam, with the purpose of measuring and evaluating the elastic deformations on the pavement surface. To a structural evaluation, a nondestructive test using the Benkelman beam, which uses quasi-static loading, was used. The results obtained were compared and analyzed according to DNER 010/79 - PRO - Structural Evaluation of Flexible Pavements - Procedure A and DNER 011/79 - PRO - Structural Evaluation of Flexible Pavements - Procedure B, to evaluate deflections in the asphalt pavement. Thus, it can be observed that the newly constructed and reclaimed sections had low deflections and are in good traffic conditions. On the other hand, the degraded section that did not undergo interventions had high deflections and required corrective measures
