Estudo do desempenho funcional de pavimentos urbanos no município de Barra do Garças – MT através do índice de serventia urbano

Abstract

The pavement is a structure composed of different layers that has the function of providing the user with smooth, comfortable and safe traffic. Since the beginning of its service life, the pavement is subjected to the action of traffic and the weather, causing it to deteriorate over time. In order for the degradation of the structure to not intensify to the point of effectively compromising the functioning of the pavement, or for the necessary maintenance to become economically unsustainable, it is essential to establish a pavement management system that implements periodic preventive maintenance on the roads. This system uses indexes that assess the conditions of the pavement, allowing the assessment of the most opportune moment, as well as the type of appropriate maintenance to be performed in each situation. The Urban Service Index (ISU) is a parameter, developed by Villibor et. al. (2009), which allows the specific assessment of urban pavements. Thus, the present work sought to analyze the conditions of the pavement surface of Av. José dos Santos and Av. Antônio Francisco Cortês and their respective roundabouts, both belonging to the city of Barra do Garças - MT, through ISU, according to the methodology proposed by Villibor et. al. (2009). The results showed that the studied roads were in precarious conditions, presenting low ISU values and, consequently, should undergo a process of reconstruction or reinforcement. The roundabout belonging to Av. Antônio Francisco Cortês, among the stretches studied, was the one with the best condition, requiring only the application of asphalt micro concrete; while for the roundabout of Av. José dos Santos the solution is conventional resurfacing with hot machined bituminous concrete (CBUQ).
