Evaluation of the Bailey Method as a tool for improving

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.

An Evaluation of the Bailey Method to Predict Voids in the

The Bailey Method was developed by Robert Bailey of the Illinois State DOT. It was intended to be a tool to predict changes in voids in the mineral aggregate (VMA) resulting from gradation alterations in compacted asphalt concrete samples. This research evaluates the changes in VMA due to gradation alterations of four contractors’ mix designs.

Marshall Mix Design - Pavement Interactive

The Marshall method, like other mix design methods, uses several trial aggregate-asphalt binder blends (typically 5 blends with 3 samples each for a total of 15 specimens), each with a different asphalt binder content. Then, by evaluating each trial blend’s performance, an optimum asphalt binder content can be selected.

Volumetric Design for Hot-Mix Asphalt (HMA

1.1 This standard for mix design evaluation uses aggregate and mixture properties to produce a hot-mix asphalt (HMA) job-mix formula. The mix design is based on the volumetric properties of the HMA in terms of the air voids (V ), voids in the mineral aggregate (VMA), and voids. a. filled with asphalt (VFA).
