Gradation and Size - Pavement Interactivel

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

Gradation Test - Pavement Interactivel

The standard gradation and sieve analysis test is: AASHTO T 27 and ASTM C 136: Sieve Analysis of Fine and Coarse Aggregates; Background. The particle size distribution, or gradation, of the constituent aggregate (Figure 3) is one of the most influential characteristics in determining how an HMA mixture will perform as a pavement material.
