SIEVE ANALYSIS OF FINE AND COARSE AGGREGATES WAQTC
In determining sieving time for sieve sizes larger than 475 mm (No 4), limit the material on the sieve to a single layer of particles Overload Determination For sieves with openingsweights retained on each sieve should be within 03% of the original weight of the sample prior to grading Particles larger than 3 in (75 mm) should be handSIEVE ANALYSIS OF FINE AND COARSE AGGREGATES AASHTO T 27

For ï¬ ne aggregate, 203mmdiameter sieves are often used The maximum amount of aggregate retained on sieves of this size should be limited to about 194 g; larger amounts may result in inaccurate sieveNote 1: Nominal maximum particle size is defined as "the largest sieve in the applicable specification upon which any material is permitted to be retained" 44 For OPSSMETHOD OF TEST FOR SIEVE ANALYSIS OF AGGREGATES Road

SIEVE ANALYSIS OF FINE AND COARSE AGGREGATE
A sieve is considered overloaded when the mass of the material retained on a sieve exceeds the maximum allowed as follows: The amount retained on the sieve is determined by weighing In some versions there is an integral weighing system to determine the progressive weight loss of the sieve It is possible to calibrate sieves and compare results with particle size analyses made by other methods ( Leschonski, 1981 )Sieve Analysis an overview | ScienceDirect Topics
