Analysis of a prioritization index for the maintenance of flexible pavements of a university campus

Abstract

Pavement Management Systems play an important role in assisting decision making regarding activities related to road infrastructure. Thus, from the knowledge of the conditions of the pavements, the manager will have subsidies to decide when, where and how to intervene to provide adequate levels of comfort, safety and savings to users. In the urban area, it is common to use the prioritization technique to select the candidate roads for maintenance services. Therefore, it is intended to contribute to the public management of municipalities by taking a university campus as a laboratory. Thus, the aim of this research is to analyze the application of a multicriteria prioritization index to the maintenance of the flexible pavement network. In this study the priority order from the index developed based on Multicriteria Decision Analysis Constructivist (MCDA-C) is compared to that of traditional indexes. For the analysis it was used data obtained in objective and subjective surveys in 2017 and 2018. From the results it was noted that the multicriteria index had its results close to the traditional indexes only in 2018. In general, it was noticed that the index provided compatible results using both objective and subjective evaluations. It is concluded that the multicriteria index can be applied in the prioritization of flexible pavements candidates for interventions.
