Question

The correct sequence of the increasing order of the disturbance to soil samples obtained from chunk, piston, split spoon and remoulded sampler is

• A. piston sampler, chunk sampler, split spoon sampler, remoulded sampler
• B. chunk sampler, piston sampler, split spoon sampler, remoulded sampler
• C. piston sampler,chunk sampler, remoulded sampler, split spoon sampler
• D. chunk sampler, piston sampler, remoulded sampler, split spoon sampler

Answer 1

The correct option is B chunk sampler, piston sampler, split spoon sampler, remoulded sampler

Piston sampler is a thin type sampler used in case of soft sensitive clays for obtaining very fine undisturbed samples. Chunk samples are considered equivalent to undisturbed samples.
Split Spoon sampler gives disturbed but representative samples and can be used in all soil types.
Stationary Piston Sampler is ideal in case of soft and saturated soils.
