Avaliação objetiva da superfície de pavimentos asfálticos com o uso de geotecnologias

Abstract

The usual method of objective evaluation of pavement condition specified by DNIT is a hard task. Considering this problem, it is noticeable that the use of remotely piloted aircraft is suitable as a possible solution for quick data collection and analysis. The objective of this work is to evaluate part of the structural bus corridor of João Naves de Ávila Avenue in the city of Uberlândia, through the execution of walking methods and analysis of the orthomosaic formed by the images captured by the UAV, calculating the global gravity index for each case, comparing the results of the two forms of evaluation, and seeking to investigate the efficiency of photogrammetry in the inspection of the condition of the surface of pavements. The analyses resulted in divergent pavement condition parameters, presenting "bad" condition in the objective walking evaluation method and "good" in the orthomosaic analysis method. The 2D analysis is not totally faithful to the reproduction of the defects in the road because it does not allow measuring the depth of the wheel tracks at the workstations.
