Question

The energy per volume for Heavy compaction test is ______________

(a) 593 kJ/m^3

(b) 2944 kJ/m^3

(c) 2674 kJ/m^3

(d) kJ/m^3

I had been asked this question by my college professor while I was bunking the class.

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

Answer 1

Right choice is (b) 2944 kJ/m^3

The best explanation: The energy per volume is,

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

W=4.9kg, h=490mm, N=5, n=25 and V=1000 cc.

∴ EMPT=4.9*490*5*25/1000

∴ EMPT=2944 kJ/m^3.
