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.
