Avaliação do ciclo de vida da operação da rota Santa Maria – RSC 287.

Abstract

Today, road transport is the most commonly used mode and has a growing global scale of new highway construction. Therefore, the construction, use, maintenance, and disposal of waste generate significant impacts, making it more concerning in terms of environmental sustainability. Given the importance of understanding the construction, maintenance, and operation phases of a highway in a more sustainable manner, this dissertation applied literature review methodologies on Life Cycle Analysis (LCA) concerning highway maintenance, as well as the Life Cycle Assessment (LCA) methodology on data from a section under concession in the state of Rio Grande do Sul, Brazil. Direct and estimated data from a single Scope Scenario were considered, with a reference flow of 1 year of operation for 204.51 km of highway on the RSC-287 between Tabaí and Santa Maria, with five toll booths and vehicle traffic ranging from 2,170,942 to 2,287,363 vehicles between 2022 and 2023. The midpoint impacts of maintenance considered resource consumption, inhalable emissions, non-carcinogenic substances, and global warming as the main impacts. The endpoint impacts on Resources and Human Health are the most representative for managing improvements in future planning of one of the sustainability points.
