Embankment Quality and Assessment of Moisture Control Implementation. Tech Transfer Summary
Earth embankments are designed to provide the specified elevation and stability for the performance life of the overlying pavement systems and embedded drainage structures. Past research shows that significant variability exists in the final compaction conditions (e.g., moisture content) for embankment fills and that variability in compaction quality is largely influenced by wet Iowa fill materials and variable lift thickness control and compaction operations. Past experimental pilot projects have been conducted in Iowa to document compaction quality using the “walk out” roller specification versus end-result alternative requirements including moisture/density control and use of dynamic cone penetration testing as a measurement of lift thickness, uniformity, and soil strength.
