TEST 5: Measurement of Field Density by Sand Cone Method Introduction: The sand cone method employs the use of a uniformly graded sand to fill a test hole. The hole is hand excavated in the soil and all the material from the hole is saved in a container. The hole is filled with free-flowing sand of a known density, and the volume is determined.
A sand-cone method is commonly used to determine the density of compacted soils. The density of the compacted soil calculated from the sand-cone method could be correct, provided the calibration container has approximately the same size or volume and allows the sand to fall to approximately the same height as a test hole in the field.
SAND CONE METHOD . Consult the current edition of AASHTO for procedure in its entirety and equipment specification details. SCOPE . This method covers the determination of the in-place density of compacted soil or soil-aggregate mixtures. The in-place dry density is expressed as a percentage of the soils maximum dry density and can be compared to
Scope* 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 ...

The document describes a laboratory experiment to determine soil properties using the sand cone test method. It includes the objectives, apparatus, theory, procedure, observations and calculations for the test.
FIELD DENSITY BY THE SAND CONE METHOD (A Modification of AASHTO Designation T 191) SCOPE 1. (a) This method is used to determine the density of compacted soils or aggregates by determining the weight and moisture content material removed from a test hole and measuring the volume of the test hole.
