This report focuses on the effectiveness of air convection embankments (ACE) and ventilated shoulder (VS) cooling systems designed to cool foundation soils and preserve permafrost beneath roadway embankments. The three main sections of the report include a literature review, an analysis of field data from Thompson Drive and the Alaska Highway Dot Lake test site, and a discussion of techniques for modeling ACE and VS structures.
