Field Density Testing
Field Density Testing is carried out in the field to determine the insitu density of the material
Laboratory Soil Compaction Tests
Are carried out to the maximum laboratory dry density of a material. For Civil Construction Field Density testing is the most common. It is used to determine the Dry Density and Moisture Content of the material being tested. The Field Density is usually compared with a laboratory compaction test of the same soil type, to produce a ratio between field and laboratory compaction. Compactions are either performed as Standard or Modified.
California Bearing Ratio
Is a test to determine the bearing capacity of a soil or aggregate sample. It is used to determine the strength of a soil usually for the purpose of designing a road pavement, accounting for traffic loads.
Particle Size Distribution test results (or Grading’s)
Are used for many reasons such as determining the compliance of manufactured gravels with required standards and specifications in the earthwork and concrete stages of construction works. This Soil test is also part of the process used to classify a soil sample in conjunction with Atterburg Limits testing
Cover a range of soil tests relating to reactivity to moisture (water), better known as Plasticity. These tests include Liquid Limit, Plastic Limit, Plasticity Index and Linear Shrinkage. Atterburg Limits play an important part when classifying soil types and work in conjunction with Particle Size Distribution tests (above).
