Avaliação funcional das rodovias federais do estado do Ceará com um estudo de caso na BR-116

Abstract

The road modal is the most used in Brazil, however, the country's highway network, in its vast majority, has several defects in its extension, a factor that reduces safety and comfort in the modal, in addition to generating higher operating costs. Therefore, this work aims to analyze the pavement conditions on federal highways in the state of Ceará through data provided by the National Department of Transport Infrastructure and through a case study on BR 116. The data were analyzed according to the pavement quality limits required by the highway exploration program, which should be complied with. In the case study, the verification of defects on the pavement surface was carried out using the Continuous Visual Survey method to classify the state of conservation in the stretch. The results obtained showed that the functional condition of the pavement of 7 of the 10 highways analyzed have more than half of their extensions below the limit required by the Highway Exploration Program, in addition, the case study showed that 40% is in a bad condition, 40% in a worse condition, 10% in a regular condition and 10% in a good condition. It is important to highlight that there was a divergence with data from the National Department of Transport Infrastructure for the analyzed stretch, nevertheless, must take into account the subjectivity in the classification of the condition of conservation of the highways, a fact that may have led to differences in the results.
