METODOLOGIA DI APPROCCIO INTEGRATO SOSTENIBILITA’ - RESILIENZA NELLA RIABILITAZIONE DELLE INFRASTRUTTURE VIARIE DOPO EVENTI ESTREMI

Sustainability and resilience are relevant concepts in design and management of transport infrastructures. Sustainability refers toconcept 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 ofrecovery the previous functionality. Traditionally, the two concepts are applied separately even if they present a significant number ofsimilar characteristics. The better solutions in transport infrastructures design, maintenance and rehabilitation should lead to an improvementof both qualities. This paper presents an integrated approach sustainability-resilience as a useful tool in the decision-makingprocess where different alternatives of rehabilitation after an extreme event are considered. Sustainability and resilience are estimatedbased on LCCA. The integrated perspective allows addressing an appropriate amount of technical, economic and environmental issuesand is an useful tool for the identification of the most efficient solution.
