This paper presents a case study of the flaws of flexible pavement in some urban roads in the municipality of Alegrete. The methodology was based on two evaluation methods of the Departamento Nacional de Infraestrutura de Transporte for road pavements: Objective Evaluation of surface, to determine the Global Severity Index, and the Subjective Evaluation of surface, for obtaining the Current Value of Usefulness. The research was conducted in the following way: Av. Assis Brasil, Av. Dr. Lauro Dornelles, Rua dos Andradas, Rua Barão do Amazonas e Rua Bento Manoel. These roads have been selected for their representativeness in urban Alegrete, and in total, the extension of 4.56 km was analyzed. We carried out a photographic survey for the characterization of pathologies found in order to identify possible causes and solutions. Based on qualitative survey degradation, attributed a concept for pavement considered in the light of the IGG. As for comfort to the bearing, grades were attributed according for 6 evaluators chosen for routes studied, reaching an average for the classification of the level of usefulness of the same. The solutions presented in this study were of two types of maintenance: preventive and corrective. The preventative is related to avoid future occurrence of pathologies while corrective measures are related to remedy the disorders. Finally, the paper reports the importance of planning and management of maintenance on urban roads.
