Compaction Related Tests

Compaction related tests such as moisture/density relationships, Californian Bearing Ratio (CBR), and Moisture condition value (MCV) are standard requirements for ground investigation and earthworks projects. Our suite of tests include:

Light/Heavy/Vibrating Hammer Compaction Tests

Heavy (4.5kg), Light (2.5kg) and vibrating hammer compaction tests are carried out by ESG Laboratory Technicians on materials including those which may be susceptible to crushing. The vibrating hammer test normally applies only to non-cohesive materials.

California Bearing Ratio (CBR)

Californian Bearing Ratios (CBR) are often carried out by ESG on either a recompacted specimen or an undisturbed sample recovered in a CBR mould.

Maximum & Mininum Densities

Our maximum and minimum density tests are ideal for samples with less than 10% fines and at least 90% passing a 37.5mm sieve to derive limiting density criteria for assessment of in situ relative density and porosity.

Moisture Content Value - MCV (Relationship)

A standard test to ascertain moisture content/MCV relationship allowing derivation of acceptability criteria.

Moisture Content Value - MCV (One Point)

Our 'one point' test for MCV is designed to ascertain a material's 'natural state' moisture condition value.
