Avaliação funcional de pavimento flexível de tráfego médio através do índice de gravidade global - IGG.

Abstract

The functional assessment of the pavement is essential to ensure that highways meet the quality standards required by law, thus promoting safety and comfort for the user, as well as efficiency for the road system. However, when the desired requirements are not met on the pavement, the process of pavement degradation through pathologies can begin, making it necessary to carry out evaluation methods for subsequent maintenance on the road. Thus, the work aimed to conduct a functional assessment using the Global Gravity Index (IGG) method on a flexible pavement, located in the Aluízio Campos complex, in Campina Grande - PB, aiming to detect possible surface flaws, in addition to characterizing the pavement regarding its quality of use by the concepts standardized by DNIT. The research was qualitative and quantitative. The methodology involved a volumetric count of traffic requesting the pavement. Then, the pathologies that appeared on the road were identified, in addition to collecting data to carry out the IGG method. With the completion of the analysis, the highway was classified according to the concept of comfort and safety for users. The volumetric traffic count showed that it was possible to understand the causes of each detected defect. The identification of each defect was necessary to be able to consider its relevance in the degree of pavement degradation. At the end of the application of the method, it was observed that the pavement has a “Poor” rating regarding the comfort and safety of drivers, due to the severity of the defects found. According to the concept presented, a more complete study must be carried out later, in addition to restorations along the highway to improve it compared to the current concept in which it occupies.
