Clegg Impact Soil Tester
The Clegg Impact Soil Tester provides a simple means of testing the design and construction of pavement overlays, subgrades and earthworks and for confirming uniform compaction over wide areas. It is also a valuable tool in checking compaction levels during trench reinstatement after pipe or cable laying. The Clegg Impact Soil Tester can be utilised to identify poorly compacted areas. Defective work can be detected and remedied as it arises, thereby avoiding ineffective compacting or rolling. The tester has a hand-held readout meter that displays a digital reading known as an Impact Value (IV) that is related to the stiffness of the material being tested. The Impact Values give an indication of soil strength and show good correlation with results from CBR tests. Data from the Clegg Impact Soil Tester can therefore be used in a similar manner to results from CBR tests performed in the laboratory and in the field.
