COMPACTION COMPARISON TESTING USING A MODIFIED IMPACT SOIL TESTER AND NUCLEAR DENSITY GAUGE

This paper presents a study that compared test results of a modified Impact Soil Tester (IST) on compacted soil with data obtained from the same soil using a nuclear density gauge at the U.S. Army Corp of Engineer's Buena Vista Flood Wall project in Buena Vista, Virginia. This comparison testing demonstrated the credibility of the procedure developed for the IST as a compaction testing device. The comparison data was obtained on a variety of soils ranging from silty sands to clays. The Flood Wall comparison compaction data for 90% Standard Proctor shows that the results of the IST as modified are consistent with the nuclear density gauge 89% of the time for all types of soil tested; however, if the soils are more cohesive, then the results are consistent 97% of the time. These comparison tests are in general agreement with earlier testing using the same techniques and methods on compacted backfill in utility trenches.
