Compaction & CBR Test Equipment

This test method utilises a 2.5 kg hand compaction hammer and a one litre capacity compaction mould. Often referred to as the ‘Proctor’ test it is suitable for soils containing particles no larger than 20 mm. The mould and hammer is manufactured from corrosion protected steel components to withstand the heavy usage involved in the test.

This test method utilises a 4.5 kg hand rammer resulting in a heavier compactive effort than the 2.5 kg test method. Compactive energy some 4.5 times greater is applied to the sample using the heavier rammer.

The method is often specified where higher levels of compaction are necessary in a structure, e.g. an airfield sub-base material. Manufactured from corrosion protected steel components the 4.5 kg rammer is designed to withstand heavy usage involved in the test method.

• Pre-set blow pattern ensures even compaction
• Solid state controls for reliability and ease of maintenance
• Automatic re-setting of counter after completion of blow pattern

These machines automatically compact specimens eliminating the laborious hand compaction method. The height of the rammer is selectable to suit test requirements. The weight of the rammer is selectable. An automatic blow pattern ensures optimum compaction for each layer of soil. The rammer travels across the mould and the table rotates the mould in equal steps on a base that is extremely stable. The number of blows per layer can be set at the beginning of the test.

A range of load rings will be required depending upon the type of material being tested. Detailed below is a selected range of load rings and transducers that are suitable for differing values of CBR.

The in-situ CBR jack assembly can be mounted in a simple conversion frame to measure CBR values in the laboratory. The frame is used with the jack, a suitable load ring, CBR mould and penetration piston.
