ABSTRACT
Representative Medium Partially deformed such as in split barrel sampler. Fabric/ structure, strength compressibility and permeability expected to be changed. Classification tests
Continuous Medium/high Hole is advanced using continuous piston or thin walled tube sampling. Obtains a full strata profile
Undisturbed High Tube or block samples for strength and deformation testing. Tube samples are obtained from boreholes and block samples from test pits
◦ Disturbed samples obtained from augers, wash boring returns on chippings from percussion drilling.
