The minimum and maximum void ratios are required to establish the relative density of sandy soil. Undisturbed simple shear test specimens are often too small to provide enough material to employ the Japanese Standard JIS A 1224:2009 Test Method. An alternative test method for evaluating the dry minimum and maximum densities of soil is proposed for those cases when a test specimen does not provide enough material to use the standard-size mold. The alternative test method was applied to soil from 42 small test specimens. Soil from test specimens of the same material were subsequently mixed to produce eight soil composites for which their minimum and maximum densities could be determined using both the standard and alternative methods. The minimum and maximum void ratios determined by both methods for the composite soil are in good agreement. Moreover, trends in the dataset are consistent with those from previous studies on sand and non-plastic fine-grained soil.
