ASTM D1556/D1556M-15e1

Standard Test Method for Density and Unit Weight of Soil in Place by Sand-Cone Method

1.1 This test method may be used to determine the in-place density and unit weight of soils using a sand cone apparatus.

1.2 This test method is applicable for soils without appreciable amounts of rock or coarse materials in excess of 11/2 in. [38 mm] in diameter.

1.3 This test method may also be used for the determination of the in-place density and unit weight of intact or in situ soils, provided the natural void or pore openings in the soil are small enough to prevent the sand used in the test from entering the voids. The soil or other material being tested should have sufficient cohesion or particle attraction to maintain stable sides on a small hole or excavation, and be firm enough to withstand the minor pressures exerted in digging the hole and placing the apparatus over it, without deforming or sloughing.

1.4 This test method is not suitable for organic, saturated, or highly plastic soils that would deform or compress during the excavation of the test hole. This test method may not be suitable for soils consisting of unbound granular materials that will not maintain stable sides in the test hole, soils containing appreciable amounts of coarse material larger than 11/2 in. [38 mm], and granular soils having high void ratios.

1.5 When materials to be tested contain appreciable amounts of particles larger than 11/2 in. [38 mm], or when test hole volumes larger than 0.1 ft3 [2830 cm3] are required, Test Method D4914 or D5030/D5030M is applicable.
