12/1/2014· Sieve Analysis (ASTM C 136, AASHTO T-27): This test method evaluates the gradation of aggregate using a series of sieves. The results are then plotted on to a semi-log aggregate gradation chart. This chart shows the particle size distribution for any given aggregate and can then be better evaluated for its use in portland cement concrete and ...
Concrete Aggregate Combined Gradation Example Page 5 of 6 Combined aggregates that tend to plot above the Power Chart line will tend to be stiff and may require high doses of high range water reducer. Blends that plot far below the Power Chart line are too coarse and tend to segregate.
10/11/2012 7 Road Aggregate 101: Nominal maximum and/or minimum sized stone in mix The nominal size distribution of an aggregate specification is defined as the range of sieve openings through which of the aggregate can pass. Road Aggregate 101: Gradation or distribution of different sized stones
Aashto Aggregate Gradation Chart. Use from all supply sources.The gradation must be uniform from any one source and not change from the low to the high gradation limits.The fineness modulus of samples taken from proposed sources must be a minimum 2.50 and a maximum 3.10 when tested under aashto m 6.Fine aggregate.

AASHTO #57 Stone Specs AASHTO #57 stone as defined by quarries, state agencies, etc. is an open-graded, self-compacting aggregate blend of size 5, 6, & 7 stone. This material cannot be 'compacted' in a true sense, but can be properly oriented with compaction equipment. This is particularly important when using #57 stone under Flexi-Pave surfaces.

When gap-graded aggregate are specified, certain particle sizes of aggregate are omitted from the size continuum. Gap-graded aggregate are used to obtain uniform textures in exposed aggregate concrete. Close control of mix proportions is necessary to avoid segregation.

An optimized gradation based on aggregate availability and project requirements will result in an economical concrete with good workability and finishability. The proportions between coarse and fine aggregates will change based on the unique characteristics of each aggregate, the placement method, and the finish desired.
