The next step is to select different adaptation pathways for additional performance and cost analysis using three emissions and sea-level rise scenarios. An adaptation pathway is a prescribed series of adaptation actions to be taken over time. An adaptation plan consists of several adaptation pathways with tipping points that mark where you can change from one adaptation pathway to another in response to changing climate scenarios, new materials, substantial changes in traffic volume, continuous surface-water flooding as with sea-level rise, or other. In this case study, the adaptation pathways are a series of adaptation actions including asphalt overlays and/or increasing the thickness of the granular base course as rehabilitation alternatives to maintain 85% reliability of the pavement structure for the period 2020-2080 (Knott et al., 2019). The marker “X” indicates when AC overlays should be applied and bullseye symbols indicate when a transfer to another pathway can occur, if necessary. The selection of an adaptation pathway is dependent on funding and constructionrelated constraints. Many organizations have begun to plan for climate change by identifying vulnerable transportation assets and including climate change in the planning process. An important step toward designing resilient pavement systems is to know how environmental factors such as increasing temperatures, precipitation and sea level will impact pavement infrastructure and how to modify design practices. Now more than ever, there is a critical need to include accurate and reliable short- and long-term climate information in pavement design and M&R decision process. All three approaches mentioned herein may be used to account for climate change using future climate projection data. The selection of a given approach should be aligned with the goal and scope of the study and agreed upon by all stakeholders. To learn more, visit www.asphaltpavement.org/resilience.
