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. See more
