TO-112 - Proctor Compaction Apparatus (BS)
Hand compaction hammer.
Compaction test 2.5kg
This test method utilizes a 2.5kg hand compaction hammer and compaction molds are made of corrosion protected steel. Often referred to as the ‘Proctor’ test, it is suitable for soils containing particles no larger than 20mm.
Note: Both hand compaction hammer and compaction molds are made of corrosion protected steel to withstand the heavy usage involved in the test.
Compaction test 4.5k
This test method utilizes a 4.5kg hand rammer resulting in approximately 4.5 times greater compactive energy being applied to the sample with the heavier rammer. This method is often specified where higher levels of compaction are necessary in a structure, e.g. an airfield sub-base material.
Note: Manufactured from corrosion protected steel components, the 4.5 kg rammer is designed to withstand heavy usage involved in the test method. Compaction test 4.5kg.
