ABSTRACT

ABSTRACT: Bridges and viaducts are of paramount importance for the development of cities, and the effectiveness of these structures depends on regular maintenance to which they are subject. The ways these inspections are made today are quite rudimentary. Therefore, this study aimed to evaluate the potential use of remote sensing equipment, the Terrestrial Laser Scanning (TLS) to detect pathological manifestations on bridges and concrete viaducts. The methodology consists of scanning areas affected by pathological manifestations and post processing data by a classifier algorithm, which generated images in which it was possible to differentiate the pathological manifestations and concrete area. The results showed that the use of the return pulse intensity information acquired by the TLS identify the areas affected by biodeterioration, humidity and efflorescence on the concrete surface and can therefore be used to complement the current methodology of inspection of bridges and viaducts.
