    Abstract

    A review of laboratory density measurement techniques suggests that the density pan and the density scoop constitute a useful and complementary pair of methods. Both are described in detail and analyzed with respect to bias and random error. Of the two techniques, the density pan is most useful in loose sand and has a coefficient of variation of about 1% for dry, medium-grained sand. The density scoop is most useful in medium to dense sands and also has a coefficient of variation of about 1%. Using these two techniques and a simplified statistical procedure described in this paper, an experimenter can design a program of measurements to measure the density of a given deposit with any desired level of confidence.
