Resilient Pavements
Climate change poses a direct challenge to the integrity of U.S. infrastructure, including U.S. pavement transportation systems. Order 5520 sets forth FHWA’s policy to prepare for and address infrastructure resilience. The Bipartisan Infrastructure Law defines resilience as:
… a project with the ability to anticipate, prepare for, or adapt to conditions or withstand, respond to, or recover rapidly from disruptions, including the ability--
(A)(i) to resist hazards or withstand impacts from weather events and natural disasters; or
(ii) 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.
For the full definition, see sec. 11103 of the Bipartisan Infrastructure Law (BIL), enacted as the Infrastructure Investment and Jobs Act, Pub. L. 117-58 (Nov. 15, 2021).
Disruptions to pavement infrastructure originate from climate stressors. A few examples of climate stressors of concern include, but are not limited to, extreme events, increased temperature, precipitation, sea-level rise, and wildfires.
