A. PURPOSE AND USE OF IN-PLACE DENSITY OR UNIT WEIGHT TESTS In-place density or unit weight tests are performed on the soil to determine the undisturbed or in-place soil properties for field quality-control purposes to determine whether an earth or rock fill has been compacted to the desired or specified density or unit weight. The field in-place density tests are also conducted for making comparisons and calculations related to volume and weight relationships such as void ratio or degree of saturation. For design purposes, the tests are often conducted to provide information for calculating soil loads or stresses within a soil mass or exerted by a soil mass. Another important reason for these test procedures is to assist in the control and management of the borrow area by providing information for calculating volume differences between excavated volume and the volume of the compacted fill areas.
