PRINCIPAIS MANIFESTAÇÕES PATOLÓGICAS EM PAVIMENTOS FLEXÍVEIS: ESTUDO DE CASO DE UM TRECHO CRÍTICO DA RODOVIA DF-001 (PISTÃO SUL), TAGUATINGA/DISTRITO FEDERAL, DOIS ANOS APÓS A PRIMEIRA AVALIAÇÃO

: Highways for the growth of a country's economy, highways are responsible for the traffic of a significant part of productivity. Thus, it is extremely important to preserve and extend the life of a pavement. The present work aims to analyze and evaluate the state of the pavement surface on a critical stretch of the DF-001 highway, in Pistão Sul, located in Taguatinga / Distrito Federal, and to compare the main pathologies found after an interval of two years since the first evaluation, which was the result of a Graduation Course in Civil Engineering in 2017. In this context, for such comparisons, an objective assessment of the flexible pavement surface of the DNIT 006/2003-PRO standard was established, which establishes procedures for evaluating the surface condition of the pavement of the chosen stretch through the visual survey of apparent occurrences and in the determination of the Global Severity Index (IGG). The evaluated section presented a considerable worsening in the occurrences, with a high IGG value, and continued to be classified as a state of poor quality, reflecting on the conditions of safety and comfort.
