Abstract
Climate change is the one of the greatest challenges of our time, and it poses a threat to the surrounding built and natural environments. This review paper addresses climate change resilience in pavements by considering major vulnerability issues and adaptation measures. First, a review on foundational information of climate change related to transportation infrastructure is provided to bring all transportation professionals and practitioners to the same knowledge base on climate change terminology. Such information includes sources of climate information, climate scenarios, downscaling climate data, and uncertainty in climate projection information. Relevant climate stressors to pavements are discussed in some depth, including the most significant ones, which are increases in temperature and precipitation intensity. Thus, the proposed different engineering-informed adaptation measures relevant to the climate stressors of interest were evidence-based with reference to published peer-reviewed articles and case studies. Such adaptation solutions are related to monitoring pavement key performance parameters and pavement adaptations in structural design, robust materials and mix design, along with adaptation in maintenance, regulation, and construction. Efforts to adapt pavement systems to climate change are ongoing. In addition to such research works, this study concludes that impacts of adaptation measures on pavement and environment should be incorporated in the decision-making process in planning and design. This makes it important to integrate practical adaptation strategies in design and construction standards and guides, and implement awareness and education of climate change adaptation among engineers and practitioners.
Highlights
IntroductionClimate change has a wide range of impacts that affect infrastructure on a broad scale, though this is context-sensitive to different influences of the location and adaptive resilience capacity of governments and communities [3]
This review paper considered in detail foundational information to better understand the pavement climate change adaptation
Climate stressors relevant to pavements were discussed in some depth, the most significant of which that drove the discussion in adaption solutions being increases in temperature and precipitation intensity
Summary
Climate change has a wide range of impacts that affect infrastructure on a broad scale, though this is context-sensitive to different influences of the location and adaptive resilience capacity of governments and communities [3]. In this regard, the formal definitions of resilience and vulnerability adopted in this text are as per the Federal Highway Administration (FHWA) order 5520 [4], which are clear and comprehensive, and drive all FHWA-supported studies in relation to: . Resilience: the ability to anticipate, prepare for, and adapt to changing conditions, and withstand, respond to, and recover rapidly from disruptions; Adaptation: adjustments in natural or human systems in anticipation of or response to a changing environment in a way that effectively uses beneficial opportunities or reduces adverse effects. 4.0/).
