PARENTE, D. Cardoso; FELIX, N. Carvalho  and  PICANCO, A. Pessoa. Use of unmanned aerial vehicle (UAV) in the identification of surface pathology in asphalt pavement. Rev. ALCONPAT [online]. 2017, vol.7, n.2, pp.160-171. ISSN 2007-6835.  https://doi.org/10.21041/ra.v7i2.161.

The present research had the purpose of developing an alternative and new procedure to identify the superficial pathologic manifestations on asphalt pavement from a stretch of highway TO-050, in Palmas - TO. As tools were used: an unmanned aerial vehicle (UAV), flight plan and image processing software, mosaic of orthophotos and Digital Surface Model (DSM) of the studied area. Through the visual interpretation of the generated products it was possible to identify the pathological manifestations in its variety, comparing obtained data from the images with data of in loco inspection. Even presenting a high potential for recognition of compromised areas, it is important to highlight that the instability of the aircraft interferes considerably on the quality of the images generated.

Keywords : unmanned aerial vehicle; pathology; asphaltic pavement.
