Methods commonly used for the determination of soil compactibility require a large quantity of soil as well as much time and effort. A method is described which requires only 600–800 gm. of soil and 1 hour of time for each bulk density‐moisture curve. The compacter described is of the impact type and easily adjusted for application of a wide range of compaction energies. The procedure adopted applies three to four times as much compaction energy as the standard Proctor method. Experience has shown that a sample weight of 100 ± 5 gm. is satisfactory. It has been shown that as compaction energy increases, the maximum bulk density increases and the moisture content at which it occurs decreases. Compaction data and aggregate stability data from two different experiments show similar differences in soil physical properties due to soil treatment. In general, this instrument has proved to be very satisfactory for the measurement of soil compactibility.
