Roadway Foundation Cooling using Structured Foam Layers

This project seeks to evaluate cost-effective solutions to reduce permafrost thaw and resulting embankment deformation. Specifically, evaluating structured foam layers to result in net annual cooling effect and testing designs in a laboratory setting. This project will evaluate solutions optimizing proposed geometries to reduce the height of structured foam layers, thus reducing cost. This study could also lead to design guidelines that Alaska Department of Transportation and Public Facilities (DOT) or other design engineers could use in design.
