Question

The zero air void line shows the _________

(a) dry density as a function of water content for soil containing no air voids

(b) saturated density as a function of water content

(c) partially saturated density as a function of water content

(d) dry density as a function of specific gravity

I had been asked this question in an internship interview.

Origin of the question is Modified Proctor Test and Harvard Miniature Compaction Test in portion Compaction of Geotechnical Engineering I

Answer 1

The correct option is (a) dry density as a function of water content for soil containing no air voids

The best explanation: When the dry density is plotted as a function of water content, then for soil containing no air voids is represented by a line that is known as the zero air void line.
