Compaction Characteristics of Earth-Rock Mixtures
This report presents results of a major laboratory research investigation into the compaction characteristics of gravelly soils, i.e., earth-rock mixtures. Test gradations were based on successive scalping, had maximum particle sizes up to the 3-in. US Standard Sieve size, and contained both clay (CH) and silt (ML) fines. Laboratory compaction test procedures employing 6-, 12-, and 18-in. diameter molds with a mechanical compactor were developed and shown to be acceptably free of mold size effects. Those procedures were used to perform standard effort compaction tests on the test gradations. Analyses of the data include treatment of the effects of scalping, plasticity of fines, and gravel content on the maximum dry unit weight and optimum water content. Current methods for correcting the compaction parameters obtained on a fraction to predict those of the total material are examined. A new fill compaction control method is developed which is based on either the minus 3/4-in. or minus No.4 fraction, is more accurate than existing methods, and offers the advantage of avoidance of large-scale testing of the total materials.
