Proposta de um modelo de gerência de pavimentos urbanos para cidades de grande porte

Abstract

Given the growth of cities and the aging of urban road networks, the absence or deficiency of urban pavement management, common to Brazilian municipalities, leads to poorly planned interventions, leading to precarious scenarios of urban pavements, compromising traffic conditions and dynamics of the municipality. This work aimed to propose a management model for urban pavements in large cities through an exploratory analysis of the city of Belo Horizonte. Using the history of pavement maintenance interventions conducted by the municipal public administration between 2009 and 2021, the methodology follows the steps of characterizing the municipal road network and the maintenance actions practiced, allowing for a comprehensive analysis of the diagnosis, planning, and operationalization stages of maintenance. The results include defining the life cycle of pavements based on their functional evaluation and respective road classification, as well as guidelines for maintenance and rehabilitation strategies for each stage of deterioration over time. These strategies include preventive and corrective actions with higher performance, enabling resource optimization. By analyzing future scenarios considering the proposed urban pavement maintenance model, it was concluded that it can assist public administrators in decision-making, providing budget predictability to maintain or achieve desired service levels for the road network, with savings for the municipality and performance gains. This model can also serve as an example for other cities facing similar challenges in maintaining their road networks.
