Effective Depth of Soil Compaction in Relation to Applied Compactive Energy

Adequate compaction of highway embankments becomes more difficult to accomplish and measure as the thickness of the structure increases. As a result, Wisconsin Department of Transportation (WisDOT) specifies eight-inch embankment lifts. The construction industry, however, claims that bigger, newer compactors can be effective to depths of six feet. This study will help the WisDOT re-evaluate the eight-inch limit. Investigators will develop a method for correlating soil compaction to compactor weight, footprint, and applied energy. They will develop a system for monitoring compaction in the laboratory and field, and will identify the influence of soil characteristics on compaction. Recommendations from this research will allow specifications to accommodate new equipment and Wisconsin soil characteristics for thick, effective subgrades and quality pavements.
