The Bailey Method of gradation evaluation focuses on the aggregate properties that affect the way aggregates fit together (or pack) in a confined space or volume (See Figure 1). To analyze the packing factors, the method defines four key principles that break down the overall combined aggregate blend into four distinct fractions (See Figure 2).
