Abstract:For the Federal Highway Administration (FHWA), resilience, with respect to a project, means a project with the ability to anticipate, prepare for, and or adapt to changing conditions and or withstand, respond to, and or recover rapidly from disruptions. This includes the ability: (A) to resist hazards or withstand impacts from weather events and natural disasters, or to reduce the magnitude or duration of impacts of a disruptive weather event or natural disaster on a project; and (B) to have the absorptive capacity, adaptive capacity, and recoverability to decrease project vulnerability to weather events or other natural disasters. 23 U.S.C. § 101(a)(24). As noted in FHWA Order 5520 (FHWA 2014), climate change and extreme weather events present significant and growing risks to the safety, reliability, effectiveness, and sustainability of the Nation’s transportation infrastructure. This document examines pavement resilience, a subset of transportation resilience, and describes the state of knowledge, practice, and future needs based on (1) key national and international climate documents, (2) a FHWA approach to resilience, (3) the results of an unpublished literature review, and (4) the findings from two FHWA-sponsored Peer Exchanges on pavement resilience held in late 2020.
