Dec 27, 2014· Below is the parameter for the calculation of bulk density of soil which was obtained from the actual compaction test on site. From Item 5 on "How to do a compaction test or Insitu density test" the excavated soil from the hole shall place into a clean container or plastic container. It will be weighted as mass of the soil excavated (Me).

This test method can be used to determine the inplace density and unit weight of natural inorganic soil deposits, soilaggregate mixtures, or other similar firm materials. It is often used as a basis of acceptance for earthen material compacted to a specified density or percentage of a maximum density determined by a test method, such as Test Methods D698, D1557 or D4253 .

To evaluate the field density, it is must be compared to a control density. The control density is expressed in terms of the dry density of the minus ¾ in. (19 mm) portion of the material. The method of determining the control density is described in Section The field density, Line H, is in total wet density units.
