Question

If permeability at proctor’s maximum dry density is required, which of the following method can be used?

(a) Jodhpur mini compactor test

(b) Proctor test

(c) Compaction in permeameter

(d) All of the mentioned

The question was posed to me at a job interview.

Enquiry is from The Jodhpur Permeameter in chapter Permeability of Geotechnical Engineering I

Answer 1

Right option is (d) All of the mentioned

Best explanation: If permeability at proctor’s maximum dry density and at a moulding water content equal to the optimum value is required, first the maximum dry density and optimum water content is required is determined which can be done using Jodhpur mini compactor test, proctor test or by compaction in permeameter mould itself.
