Aggregate size #8 is nominal size 3/8 to 0.094 inch (No. 8 sieve) (9.5 to 2.36 mm). There are also a few blended or graded aggregate sizes that combine the gradation of several aggregates.

Aggregate | Washington Asphalt Pavement Association

An aggregate's particle size distribution, or gradation, is one of its most influential characteristics. In HMA, gradation helps determine almost every important property including stiffness, stability, durability, permeability, workability, fatigue resistance, frictional resistance and resistance to moisture damage (Roberts et al. 1996).

Gradation of Coarse Aggregates

• Well graded: Well-graded aggregate has a gradation of particle size that fairly evenly spans the size from the finest to the coarsest. A slice of a core of well-graded aggregate concrete shows a packed field of many different particle sizes.

For instance, nominal maximum aggregate size is usually a way to define the size of a mix when you're referring to it. So when you're saying 1/2" HMA people ...

Asphalt Aggregate Gradation and Size Testing with ...

Gradation testing, also called sieve analysis, is a fairly basic yet essential test that measures the gradation (or distribution of aggregate particles, by size, within a given sample) to determine whether it's compliant with design, production control requirements, and verification specifications.

GRADATION OF AGGREGATE FOR CONCRETE BLOCK

gradation, as well as the surface and shape characteristics of the aggregate. Workability affects green block stability, breakage, the speed at which the block can be molded, and consequently production costs.

Sieve analysis - Wikipedia

A sieve analysis (or gradation test) is a practice or procedure used (commonly used in civil engineering) to assess the particle size distribution (also called gradation) of a granular material by allowing the material to pass through a series of sieves of progressively smaller mesh size and weighing the amount of material that is stopped by each sieve as a fraction of the whole mass.
