AASHTO #57. This material has a 1-1/2 inch top size and is a clean material. Often used for backfill for retaining walls, used for subase for sheds, also sometimes used as driveway stone. Also used as the primary raw aggregate in Ready Mixed Concrete and some Hot-Mixed Asphalt mixes. Will not compact.
* Gradation Numbers 5 and 57 are yard ballast materials. 2. Old Pa # = The old Pennsylvania Department of Transportation reference to aggregate sizing. 3. DelDOT = Delaware Department of Transportation specifications, Section 813 - Grading Requirements and Section 821 -Graded Aggregates.
In PCC, gradation helps determine durability, porosity, workability, cement and water requirements, strength, and shrinkage. Because of this, gradation is a primary concern in HMA and PCC mix design and thus most agencies specify allowable aggregate gradations for both. Maximum Aggregate Size

The following chart shows example individual aggregate gradations and combined aggregate gradation information. This chart contains all the data needed to produce the three aggregate optimization charts.

The AASHTO Soil Classification System was developed by the American Association of State Highway and Transportation Officials, and is used as a guide for the classification of soils and soil-aggregate mixtures for highway construction purposes. The classification system was first developed by Hogentogler and Terzaghi in 1929, but has been revised several times since.
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.
