COMPACTION CONTROL OF EARTH-ROCK MIXTURES. FINAL REPORT
This report addresses the general subject of compaction control of fills composed of gravelly soils, i.e., earth-rock mixtures, which exhibit well-defined moisture-density (compaction) curves. The effects on the compaction curve of the addition of gravel in increasing proportions are discussed. Compaction control methods currently employed by the U.S. Army Corps of Engineers, U.S. Bureau of Reclamation, American Association of State Highway and Transportation Officials, and the U.S. Navy are discussed and compared. A new method of compaction control is described which is shown to be superior to those methods currently in use. The new method is based on either the minus 3/4-in. or minus No. 4 U.S. Standard sieve size fraction and, in most cases, does not require large-scale compaction testing of the total material gradations.
