PERFORMANCE INDICATORS FOR THE ENVIRONMENTAL MANAGEMENT OF ROAD MAINTENANCE SERVICES

Resumo

Environmental performance assessments, although widely used in several industrial sectors, is still scarcely practiced in construction, maintenance and road operation activities. Thus, there is a need for studies to interpret the state of environmental management in relation to the complexities of the road sector. In this context, the aim of the present study is, therefore, to develop performance evaluation indicators for the environmental management of road maintenance services. For this purpose, the Multicriteria Decision Analysis Constructivist (MCDA-C) model was used, involving workshops comprising professionals specialized in several areas related to the technical, academic and research sectors that could contribute to environmental management practiced in highways. In view of these considerations, 185 concepts generated from the participants' opinions were obtained, filtered into 82 criteria, and divided into 10 areas of interest. Among these, water and road safety groups presented the highest weights among the areas of interest and are thus, noteworthy. Subsequently, the descriptions of the indicators and their respective weights were determined. Managers, researchers, and technicians responsible for highway maintenance may thus apply the indicators generated in this research, to aid in environmental control of the road environment, allowing for identification of points which may stand for improvement.
