Utilização de imagens terrestres e aérea para a identificação de imperfeições no pavimento asfáltico

Abstract

The use of asphalt pavement for the movement of cargo and personnel vehicles is of utmost importance for the development of the country, so it is crucial that strategies are applied to maintain the quality of the track in good condition and extend its useful life. This work aimed to analyze and compare the use of different photogrammetry methods for the identification of imperfections in a pavement in the municipality of Romaria – Minas Gerais. The methodology consisted of the aerial image analysis, collected by a remotely piloted aircraft (RPA), and terrestrial, acquired using a mobile mapping system (MMS), to obtain information regarding asphalt pavement that could aid in the investigation of the present pathologies in the same. Based on this information, it was possible to evaluate the pathologies using the integration between aerial and terrestrial images, to create a diagnostic of these pathologies, to evaluate the quality of the pavement following DNIT norms and to infer alternatives of corrective and preventive intervention for the road mesh. From the analyzes carried out, it was possible to conclude that the use of images with different perspective points is feasible for the identification of pathologies in the road, and can be an excellent tool for decision making regarding what alternatives should be used in the asphalt pavement for the maintenance and prevention of future imperfections.
