AASHTO #57 Stone Specs AASHTO #57 stone as defined by quarries, state agencies, etc. is an opengraded, selfcompacting 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 FlexiPave surfaces.

c. Type C. Crushed gravel with a minimum of 60% of the particles retained on a No. 4 sieve with 2 or more crushed faces as determined by Tex460A, Part I. Blending of 2 or more sources is allowed. d. Type D. Type A material or crushed concrete. Crushed concrete .

Gradation of stone and rock is found by ASTM C136, the Test Method for Sieve Analysis of Fine and Coarse Aggregates. Gage numbers are used to identify aggregate. ASTM No. 57 aggregate is found using a sieve, through which all of the stones will pass. No ASTM 57 aggregate stone is smaller than a No. 8 seize with a sieve.

Gradation Specification. For instance, the gradation control points for a inch ( mm) Superpave mix specify a maximum of 58% passing and a minimum of 28% passing on the No. 8 ( mm) sieve. The Control Points Graph shows aggregate gradation control points (shown as .

Oct 17, 2013· A sieve stack is the result of fitting each sieve to be used in a given particle size analysis into the one above. The sieve with the largest mesh holes is at the top with each subsequent sieve of a tighter mesh size than the one above it. A sieve stack can consist of anywhere between 1 and 18 sieves.

Jul 07, 2014· It is the aggregate most of which passes mm IS sieve and contains only so much coarser as is permitted by specification. According to source fine aggregate may be described as: Natural Sand – it is the aggregate resulting from the natural disintegration of rock and which has been deposited by streams or glacial agencies
