Frequently Asked Questions
A soil compaction log records the results of field density testing performed on compacted fill material. Each test documents the location, elevation, lift number, measured density, moisture content, and whether the result meets the specification requirement — typically 95% of Modified Proctor maximum dry density.
Compaction percentage is the field dry density divided by the laboratory maximum dry density (from the Proctor test) multiplied by 100. For example, if the lab max is 125 pcf and the field result is 120 pcf, compaction is 96%. The template auto-calculates this for each test.
Failed compaction tests require the area to be reworked (scarified, moisture-conditioned, and recompacted) and retested. The template links failed tests to retest results and tracks the area through acceptance. Consistent failures may trigger a review of the compaction method or material.
