Acesso em: https://bdm.ufpa.br/jspui/handle/prefix/7603.https://bdm.ufpa.br/jspui/handle/prefix/7603Highways play a crucial role in the Brazilian road system, being directly associated with the country's socioeconomic growth. To ensure comfort and efficiency in transportation, it is essential to maintain their service conditions adequately. In this context, the Pavement Management System (PMS) stands out as an indispensable tool, enabling assertive decision- making based on objective data. This study aimed to determine the Global Severity Index (IGG) of the PA-252 and PA-151 highways, part of the Abaetetuba-Belém route via the Arapari port. The research involved on-site inspections in three sections, using the IGG/DNIT method to assess pavement conditions in each segment. The results showed an average IGG of 142.01 for the highways, classifying the pavement as poor. The most critical section recorded an IGG of 210.46, rated as very poor, while the best section had an IGG of 94.2, still classified as poor. The main defects identified included wear (64.67%), patches (35.33%), short transverse cracks (35.33%), and short longitudinal cracks (33.33%). Based on the analyses, solutions were proposed for asphalt surface maintenance and restoration, ranging from crack sealing to complete rehabilitation with deep milling, aiming to improve road network conditions. Thus, the study highlights the importance of IGG in planning interventions that extend highway lifespan and promote regional development.Acesso AbertoConservação de rodoviasDefeitos em pavimentos flexíveisMétodo do IGGAvaliação da condição da superfície de rolamentoHighway maintenanceFlexible pavement defectsIGG methodAssessment of riding surface conditionCNPQ::ENGENHARIAS::ENGENHARIA CIVILTrabalho de Curso - Graduação - Monografia
