In PCC, gradation helps determine durability, porosity, workability, cement and water requirements, strength, and shrinkage. Because of this, gradation is a primary concern in HMA and PCC mix design and thus most agencies specify allowable aggregate gradations for both. Maximum Aggregate Size. Maximum aggregate size can affect HMA, PCC and base/subbase courses in several ways. In HMA ...
