A sieve analysis (or gradation test) is a practice or procedure used (commonly used in civil engineering) to assess the particle size distribution (also called gradation) of a granular material by allowing the material to pass through a series of sieves of progressively smaller mesh size and weighing the amount of material that is stopped by each sieve as a fraction of the whole mass.
Aggregates for use as granular base tend to be dense-graded with a maximum size of 50 mm (2 in) or less, while granular subbase can have a nominal maximum size commonly up to 100 mm (4 in). The percentage of fines (minus 0.075 mm (No. 200 sieve)) in the granular base is limited, for drainage and frost-susceptibility purposes, to a maximum of 8
