About the research

The goal of this project is to study the effectiveness of stabilization of granular-surfaced (“gravel”) roads using wicking and non-wicking geosynthetics. The project will continue a newly established cooperative partnership with the Iowa Army National Guard that enables long-term research on granular-surfaced roads at the Camp Dodge base in Johnston, Iowa. The Camp Dodge facility contains several miles of granular-surfaced roads that routinely exhibit various types of damage and distress including rutting, potholes, washboarding, frost boils, insufficient drainage, and other moisture related damage.
