Test Method Title
Standard Test Methods for Laboratory Determination of Density (Unit Weight) of Soil Specimens
Density, unit weight
Description of Test
Method A covers the procedure for measuring the volume of wax coated specimens by determining the quantity of water displaced. This method only applies to specimens in which the wax will not penetrate the outer surface of the specimen. Method B covers the procedure by means of the direct measurement of the dimensions and mass of a specimen, usually one of cylindrical shape. Intact and reconstituted/remolded specimens may be tested by this method in conjunction with strength, permeability (air/water) and compressibility determinations.
Preferred Test Sample Size
2.87 in diameter x 3 ft Shelby tube or bulk sample (minimum 300 grams)
Number of Test Specimens
Test Specimen Size
Minimum dimension of 1.3 inches and largest particle should be smaller than 1/10 of the specimens smallest dimension.
