Usually It depends upon the soil type. Your soil investigation report should assist you in this.
say for example of common earth,
Bank soil (un excavated soil) =1661 kg / cum
Loose soil (in transit after excavation) =1163 kg / cum
Compacted soil (same soil after transit) =2077 kg / cum.
therefore,
Shrinkage factor =1661 /2077 ==0.8
Load factor =1163 /1661 ==0.7
Shrinkage = {1- (1661/2077)} x100 ==20%
Swell = {(1661/1163) -1} x100 ==42%.
Hope this helps.
