Abstract

In practice, soil compaction quality assessment relies on the determination of the in-place compacted dry unit weight, which is then compared with the maximum dry unit weight obtained from a laboratory compaction test. Most DOTs typically require that the in-place dry unit weight for compacted soil be over 95% of the laboratory maximum dry unit weight obtained from Standard Proctor compaction test results. Nuclear gauges may be used to determine the in-place dry unit weight, however, they are potentially hazardous and require safety precautions. Other tests, such as the Dynamic Cone Penetration Test (DCPT), can be used for soil compaction quality assessment.
