SpletAuburn University SpletTypically, amorphous polymers such as PC and styrenics exhibit shrinkage values on the order of 0.4% or so, whereas crystalline polymers such as PEs exhibit shrinkage values on the order of 3%. The greater the final crystallinity of the polymer becomes, the greater will be the degree of shrinkage.

Spletdifference in volume is usually defined as “shrinkage”. In estimating earthwork quantities, it is necessary to make allowance for this factor. The amount of shrinkage varies with the soil type and the depth of the fill. An allowance of 10 to 15 percent is frequently made for high fills and 20 to 25 percent for shallow fills.

ADVERTISEMENTS:

SpletOne cubic from the borrow does not translate into one cubic dumped, nor one cubic compacted. Excavation increases the volume of material, so material from the borrow expands when dumped into the truck bin, into site, or stockpiled. Conversely, material typically shrinks under compaction.
