Gradation and Size - Pavement Interactive

Maximum aggregate size can affect HMA, PCC 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). In PCC, large maximum sizes may not fit between reinforcing bar openings, but they will generally increase PCC strength because the water-cement ratio can be lowered. ASTM C 125 defines the maximum aggregate size in one of two ways: 1
