Cleanliness and Deleterious Materials - Pavement Interactive

Aggregates must be relatively clean when used in HMA or PCC. Vegetation, soft particles, clay lumps, excess dust and vegetable matter are not desirable because they generally affect performance by quickly degrading, which causes a loss of structural support and/or prevents binder-aggregate bonding.

Aggregate | Washington Asphalt Pavement Association

Maximum aggregate size can affect HMA and base/subbase courses in several ways. In HMA, instability may result from excessively small maximum sizes; and poor workability and/or segregation may result from excessively large maximum sizes (Roberts et al. 1996). ASTM C 125 defines the maximum aggregate size in one of two ways: 1. Maximum size. The largest sieve that retains some of the aggregate particles but generally not more than 10 percent by weight. Superpave defines nominal maximum aggregate
