Análise de manifestações patológicas em pavimento flexível: Estudo de caso em perímetro urbano na cidade de São Mateus - MA

Abstract

Brazil predominantly has flexible pavements on its road network. In this sense, transport infrastructure and its relevance to the country's socioeconomic progress are considered, thus emphasizing the importance, necessity and obligation of maintaining roads in excellent traffic conditions and ensuring that their pavements present good performance in the long term. However, despite the importance of the road network, there is an increasing deterioration of the asphalt coating, evidenced by the appearance of pathological manifestations. This is an exploratory study in the format of a case study that aims to provide technical contributions regarding the pathologies found in the urban perimeter in the city of São Mateus do Maranhão. The main objective of the study is to visually analyze the demonstrations along the urban perimeter in the city of São Mateus-MA, their causes and thus propose possible measures to resolve the problems presented. Therefore, based on surveys of the main pathologies present in this section, we sought to evaluate the possible causes of these defects and outline some potential solutions. To this end, field evaluation forms and on-site inspections were used to collect data. Among the pathologies identified, holes, cracks, sinking and slipping stand out, which significantly affect the safety and comfort of users. Furthermore, poor execution of the asphalt coating, especially in rainy weather conditions, contributed to the reappearance of failures. Therefore, a careful analysis of the current pavement conditions is essential for the implementation of corrective and preventive measures. Therefore, this technical knowledge is fundamental to continuously improve the road infrastructure, ensuring the safety of users and the durability of the pavement in São Mateus do Maranhão.
