Aggregates used for stone matrix asphalt mixtures are required to meet the requirements of AS aggregates in accordance with Section 904.03 (a). These requirements include testing with the Micro-Deval abrasion apparatus (AASHTO T 327) and determination of the aggregate degradation in accordance with ITM 220.

Aggregate – a mixture of specific types and sizes of crushed rock or gravel. Generally used with a binder in pavements. Also used as road base and sub-base.
SIEVE ANALYSIS OF FINE AND COARSE AGGREGATES AASHTO T 27 SCOPE The sieve analysis, commonly known as the gradation test, is a basic essential test for all aggregate technicians. The sieve analysis determines the gradation (the distribution of aggregate
ASTM No. 57 is a type of aggregate grading. The ASTM specification for this type of concrete aggregate is C 33. Stone mixes made using this type of aggregate are porous. According to "Materials for Sustainable Sites" by Meg Calkins, "larger sizes such as 57, 67 and 78 will have more rapid permeability and little susceptibility to clogging."
(X) = Stone consists largely of this size (..) = Stone can consist of up to 15% of this size (.) = Stone can consist of up to 10% of this size * Each Stone gradation can contain up to 10% upper and lower grades and some fine material (sand).

May 16, 2019· Gravel sizes can vary a little bit by location and distributor, but in most cases the crushed rock composite is available in more or less uniform sizes ranging anywhere from fine powder to pea-sized, coin-sized, or even golf ball-sized pieces. Most retailers and outlets used a numerical system to assign a size.
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.
4.1 Some contract documents specify certain aggregate sizes for specific uses or may suggest one or more of these sizes as appropriate for the preparation of various end-product mixtures. In some cases, closer limits on variability of the aggregate grading are required.
