Proposed New Standard Test Method for Laboratory Compaction Testing of Soil-Rock Mixtures Using Standard Effort
The purpose of this proposed standard is to standardize a test method for determining standard effort compaction characteristics of soil-rock mixtures containing particles larger than the 3/4-in. (19.0-mm) sieve and finer than the 3-in. (76.2-mm) sieve. The proposed method utilizes a mechanical compactor equipped with a 12-in. (304.8-mm) or 18-in. (457.2-mm)-diameter mold and a 131.4-obf (584.5-N) rammer dropped from a height of 12 in. (304.8 mm).
