Questions and Problems
12.1 (a) Discuss the effect of compaction on soil properties.
(b) Write short notes on:
(i) Field compaction control
(ii) Method of compaction (S.V.U.—B.Tech. (Part-Time)—Sep., 1983)
12.2 (a) Derive an expression for ‘zero air-void line’ and draw the line for a specific gravity of 2.65.
(b) What are the various factors that affect the compaction of soil in the field? How will you
measure compaction in the field? Describe a method with its limitations.
