Project Summary

This synthesis provides the practicing engineer with the basic knowledge required to build roadway and
airports over permafrost terrain. Topic covered include an overview of permafrost, geotechnical
investigations, slope stability, impacts of climate, and adaptation strategies during the design, construction
and maintenance phases. The purpose of the synthesis is not to provide a comprehensive body of knowledge
or to provide a complete how‐to manual. Rather the synthesis provides a working knowledge for those
working in permafrost regions such that the practicing engineer will be able to work with subject matter
experts to obtain the desired project outcomes.
