Proposta de classificação e priorização para gestão de passivos ambientais rodoviários

It is possible to find environmental nonconformities that are characterized as debts to society and the environment along federal highways. These are called environmental liabilities. When these liabilities are physical and/or material, engineering works are needed for mitigation. Since many environmental nonconformities pose installed or imminent danger, especially to road users, the surrounding population and, the environment in which they operate, together with the massive amount of liabilities present in Brazilian federal highways, justify a management plan. In this context this work proposes a road environmental liabilities management model through a classification and prioritization methodology. The proposed methodology is applied and consolidated in a database consisting of 187 liabilities collected in non-concessioned stretches of the BR 116 highway. Additionally, the management model is   implemented in case study. This study’s product stands out for addressing all the factors determined as relevant in the prioritization of road environmental liabilities in a unified manner, as well as conducting a critical analysis of the results. Therefore, it is possible to establish a concise model to manage the existing non-conformities in the national highway network, reducing the risk of accidents and assisting in the public resources’ administration.
