EXAMPLE The following results were obtained from a standard compaction test on a soil: Mass (g) Water content (%): 2010 2092 2114 2100 2055 12.8 14.5 15.6 16.8 19.2 The value of Gs= 2.67 The volume of the mold is 1000 cm3. a) Plot the dry density-water content curve b) Give the compaction characteristics of the soil c) d) Plot also the curves of zero, 5% and 10% air content lines. Give the value of air content at max. dry density.
