Manifestações patológicas em pavimentos asfálticos: estudo de caso em Macapá-AP

Abstract

Urban pavement is a fundamental component of a city's infrastructure. The presence of flaws in asphalt pavements creates insecurity for users and compromises functionality, resulting in high maintenance costs, so it requires attention for early identification. In this context, given the urban expansion and the lack of specific studies in Macapá, this work was relevant for assisting in the investigation of these defects. Therefore, the objective of this study was to analyze pathological manifestations in asphalt pavements in the city of Macapá/AP, along a stretch of Avenida dos Timbiras in the Novo Buritizal neighborhood. To achieve this, a case study was conducted through field research, with on-site inspections to identify and classify the pathologies and apply the Global Severity Index (IGG, in Portuguese). The results showed that the most frequent pathologies were potholes (35%), short longitudinal cracks (13%), patches (10%), and the IGG value was 327.69 ('poor'). Based on the analyses, probable causes were raised and possible solutions for maintenance and restoration, such as sealing and milling, were proposed. It was concluded that this study provided a comprehensive understanding of pathological manifestations in asphalt pavements at the studied location, being useful as an auxiliary tool for maintenance, and reinforcing the importance of continuous monitoring of road conditions to ensure their functionality and safety. Finally, there is a wide diversity and complexity of defects, requiring more in-depth additional analyses for the development of a strategic, cost-effective, periodic, and corrective plan that can adequately meet the needs of users.
