Life Cycle Assessment on two design alternatives of the Driva Bridge

Environmental performance of timber bridges during their lifespan has become important in recent years. In this study, two timber design alternatives of the Driva Bridge located in Norway were investigated and compared. The study applied Life Cycle Assessment (LCA) for addressing (1) the distribution of total environmental impact and energy consumption, and (2) the environmental impact and energy consumption variations due to different End-of-Life (EoL) scenarios for timber material. The results relied on five selected midpoint environmental impact indicators. It indicates that different EoL scenarios of timber can largely affect the total environmental impact, and the quantity of steel used significantly influence the total environmental impact as well as total energy consumption.     «
