Suffusion in densely compacted Satozuka pumice sand and its impact …
The grain size distribution (Fig. 6) of the pumice sand indicates that the soil is well graded with an approximately 45 % non-plastic fines content (<0.075 mm). The optimum moisture content (OMC) and maximum dry density (ρ dmax) were determined as 42.7 % and 1.068 Mg/m 3, respectively, from standard Proctor compaction tests (JIS A 1210).
