Aggregate | Washington Asphalt Pavement Association

Superpave defines nominal maximum aggregate size as "one sieve size larger than the first sieve to retain more than 10 percent of the material" (Roberts et al., 1996). Nominal maximum size . The smallest sieve through which 100 percent of the aggregate sample particles pass.

Aggregate Properties - The Concrete Portal

Aggregates that predominantly show size fractions in a limited range of sizes (such as the 20 mm and 10 mm aggregate in Figure 1) are called 'uniformly' graded, while aggregates that show a continuous gradation of size (sand in Figure 1) are called 'well' graded or continuously graded.
