Convened by the Transportation Research Board or TRB, the Transportation Resilience 2023 conference features panel discussions, expert presentations, and poster sessions. The conference is in person at the National Academy of Sciences Building in Washington, D.C., with hybrid sessions. Further, Transportation Resilience 2023 “provides attendees with information on emerging best practices and state-of-the-art research results on how to adapt transportation networks to the potential impacts of climate change and extreme weather events. The focus includes vulnerability and resilience to climate change and extreme weather events impacting all modes of transportation, including pedestrian, automobile, rail, transit, aviation, and pipeline facilities and critical infrastructure.”
The event addresses resilience integration across the transportation sector, including but not limited to, design, engineering, planning, operations and maintenance (O&M), asset management, and emergency management and communications. The target audience includes transportation practitioners, researchers, educators, consultants, government agencies, businesses, advocacy groups, and other stakeholders from around the world. Organizers welcome and encourage participation from local, tribal, state, national, and international perspectives.
ClimaTwin® is a leading climate risk intelligence solution for infrastructure assets and the built environment.
We empower infrastructure stakeholders to mitigate climate risks and assess adaptation actions across the total asset lifecycle. By connecting complex climate models and infrastructure digital twins, our solution enables engineers, owner-operators, and governments to aggregate, visualize, and analyze disparate datasets, revealing site-specific insights at a hyper-local scale. Benefits include 5-10x near-term returns and lifetime cost-avoidance by mitigating risks to systems, services, and societies.

Expansion of climate change is increasingly impacting global infrastructure systems, such as transportation networks and road systems, particularly in colder regions of the world. As temperatures warm, roads underlain by permafrost suffer a loss of integrity due to thawing permafrost — greater than half of all of the roads in Canada.
Further, as sea levels rise, groundwater impacts coastal roads. In a new study in the Journal of Cold Regions Engineering, “Climate Change Challenges for Flexible Pavement in Canada: An Overview,” the authors advocate for transportation infrastructure design to adapt policies that consider the impacts of climate change.
Authors Omran Maadani, Mohammad Shafiee, and Igor Egorov investigated the effects of climate change on roadways across Canada, and examined heat effect, permanent deformation, fatigue cracking, low temperature cracking, precipitation effects, hot mix asphalt layer, soil strength capacity, and soil freeze and thaw.
Abstract
This paper provides an outlook on the effects of climate change and the severity and frequency of extreme weather events on the performance of flexible pavements across North America. Now more than ever, the climate is changing at a rapid pace, which will alter long-term environmental loading parameters and extreme weather events. Such alterations will pose implications for the design, maintenance, and rehabilitation of flexible pavements, especially in terms of their serviceability, safety, and functionality. In northern Canada, roads are founded on various terrain types, including thaw-sensitive ice-rich permafrost underlying terrains. Such roads have experienced signs of embankment and pavement damage, which are usually induced by the degradation of the underlying permafrost due to climate change. Therefore, the development and implementation of new permafrost thaw mitigation techniques for vulnerable roads are essential and will be discussed in this paper. Resilient flexible roads should be designed to withstand the conditions that are likely to occur during their design life, taking into account the impact of the climate change on pavement performance in response to daily and seasonal changes in heat, precipitation, freeze–thaw cycles, and extreme weather events.
