Compaction Testing at i2 Analytical

Compaction Testing at i2 Analytical

Compaction testing of soil is the process by which the solid particles are packed more closely together, usually by mechanical means, thereby increasing the dry density of the soil.

To determine the compaction criteria of a soil that will ultimately be used for the on site compaction process, a range of compaction related tests are undertaken. These tests enable the relationship between dry density and moisture content that will reduce the void content of a material. This in turn will increase its strength and reduce subsequent consolidation via moisture and soil particle movement under load.

Compaction testing in the laboratory is used on site to control the earthworks compaction process by the contractor and is known as ‘end product testing’. These tests will help determine the compaction plant and methodology on site and will help in highlighting changes of material as a project proceeds, generally via pass/fail criteria. Compaction testing in the field to ensure compliance is undertaken using a range of methods, all undertaken by i2 Analytical Site Services teams.

i2 Analytical are able to undertake all standard methods on earthworks and construction materials as well as other related tests such as Moisture Condition Value (MCV) and CBR testing, including measurement of swelling characteristics.
