AGGREGATE BLENDING FOR ASPHALT MIX DESIGN: BAILEY METHOD. From the beginning of asphalt mixture design it was desired to understand the interaction of aggregates, asphalt, and the voids created during their compaction. In asphalt mixture design, guidance is lacking in the selection of the design aggregate structure and understanding the ...

The Bailey method is a systematic approach to blending aggregates to achieve the desired mixture properties (Vavrik 2000; Vavrik et al. 2002a,b). The method has been used since the early 1980s throughout the state of Illinois. The Bailey method can be used with any mix design method but the method itself is not a mix design method.

In mixing aggregates with varying gradations (coarse and fine aggregate), The Bailey method is a systematic methodology that offers aggregate interlocking as the backbone of the framework and a controlled gradation to complete the blends. Six types of gradation are used according to the bailey method considered in this study.
Chat OnlineThis article focuses on the Bailey Method, a tool for understanding aggregate packing and how it relates to compactability and segregation susceptibility. This method of gradation evaluation can help define coarse and fine in an aggregate blend, break the blend into narrow size ranges, and look at particle distribution within each range.

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).

Currently the NHDOT uses the Superpave method to design and evaluate its asphalt pavements; however, this method lacks guidelines to adjust an aggregate blend that yields unacceptable mixtures. The objective of this project was to determine if the Bailey Method of aggregate blending would help improve the rutting resistance of mix designs that use NH aggregates.
