Question

The energy per volume for Light compaction test is ______________

(a) 593 kJ/m^3

(b) 2944 kJ/m^3

(c) 2674 kJ/m^3

(d) kJ/m^3

I got this question in unit test.

Question is from The Dietert, Abbot Compaction Test and Jodhpur Mini Compactor Test in section Compaction of Geotechnical Engineering I

Answer 1

Right choice is (a) 593 kJ/m^3

Best explanation: The energy per volume is,

\(\frac{WhNng}{V} \), and for Light compaction test,

W=2.6kg, h=310mm, N=3, n=25 and V=1000 cc.

∴ ELCT=2.6*310*25*3/1000

∴ ELCT=593 kJ/m^3.
