Análise das manifestações patológicas em viadutos: estudo de caso

Abstract

Viaducts are urban equipment of great importance for the social and economic growth of cities, as well as for daily activity, interfering in the daily life of the population, enabling traffic, reducing paths and causing improvements in urban mobility. The absence of viaducts ends up changing life in the cities, becoming a real chaos. The present work deals with the analysis of pathological manifestations in the viaduct, through the execution of a case study. The viaducts adopted for the study were the Valterci de Melo and Deocleciano Moreira Alves viaducts, located on Avenida Brasil, a high-flow road in the municipality of Anápolis. Such viaducts were chosen because of their location and because they visually present pathological manifestations, even though they were recently built. The viaducts under study are actually a single viaduct, which was divided into two, just to honor two different people, and for this reason, in the present work, it will be treated as a single viaduct. The case study included visual inspection of the viaduct and mapping of anomalies. From this, the following pathological manifestations were identified in the viaduct: corrosion and reinforcement exposure, detachment, pitting, irregularity in the concrete, efflorescence, cracking in the concrete, drainage failures, wear of the expansion joints, irregularity in the pavement, cracking in the pavement and pavement wear. An analysis of each pathological manifestation was carried out and its possible causes were determined. Through the information obtained in the diagnosis, he presented the prognosis and, lastly, appropriate therapies were recommended for each pathological manifestation found in the viaduct. It is concluded that the viaduct has the end of its useful life, due to the presence of pathological manifestations. In view of this, it is of paramount importance to carry out immediate interventions on the viaduct by the responsible agency. In order to correct anomalies and restore the viaduct's performance and durability conditions. It is worth mentioning that after the correction of anomalies, it is ideal to carry out maintenance, in order to preserve the viaduct.
