Avaliação funcional de rodovias através do método de levantamento visual contínuo.

Abstract

Land transportation is the main mode of transportation in Brazil, however it is noticeable that the brazilian road network is mostly unsuitable for traffic, resulting in the increase of the indirect cost on the transported products, as well as affecting safety, comfort and efficiency. Therefore, the objective of this study was to perform a functional assessment in BR 116 and CE 263, through a case study regarding the appearance of surface defects on these highways. For this, the verification of the appearance of defects in the pavement surface was performed using the Visual Continuous Survey method where it was possible to define the Flexible and Semi-Rigid Pavement Condition Indexes (FPCI), the Expedited Global Gravity Index (EGGI), and the Pavement Surface State Index (PSSI). The segment studied in BR 116 shows that 30% of the segment is in terrible condition, 20% in bad condition, 10% in regular condition, 10% in good condition and 30% in great condition, in the fraction studied in CE 263 shows that 80 % of the stretch is in terrible condition, 10% in bad condition and 10% in regular condition. The results show that the highway network of BR 116 and CE 263 are not in ideal ride conditions, it is also worth mentioning that in the studied stretches there was divergence with the data of the National Department of Transport Infrastructure, however, one should take into account the subjectivity in the classification of the state of conservation of the highways, which may have washed away the divergences in the results.
