Abstract


Sustainability and resilience are relevant concepts in design and management of  transport infrastructures. Sustainability refers to concept of development that meets the needs of the present without compromising the ability of future generations to meet their ones. Resilience is linked to the occurrence of extreme events during the life cycle of infrastructures and it is a measure of the ability of recovery the previous functionality. Traditionally, the two concepts are applied separately even if they present a significant number of similar characteristics. The better solutions in transport infrastructures design, maintenance and rehabilitation should lead to an improvement of both qualities. This paper presents an integrated approach sustainability-resilience as a useful tool in the decision-making process where different alternatives of rehabilitation after an extreme event are considered. Sustainability and resilience are estimated based on LCCA. The integrated perspective allows addressing an appropriate amount of technical, economic and environmental issues and is an useful tool for the identification of  the most efficient solution.
