Investigation of the Bailey Method for the Design and Analysis of Dense-Graded HMAC Using Oregon Aggregates

Historically Oregon has specified gradations for dense-graded hot mix asphalt concrete (HMAC) using a combination of broadband limits and recommended “ideal” gradations. The recent adoption of SuperPave™ and Stone Matrix Asphalt (SMA) technology has created new criteria for selecting gradations. This study evaluated a method of gradation design and analysis called the Bailey Method. The method uses specific ratios developed for aggregates in Illinois. The research involved using the Bailey Method to design and evaluate Oregon specific aggregate blends. Specimens were compacted and tested using the gradations developed under the Bailey Method. Finally, rut testing was performed on those mixture specimens. The study recommended that a modified Bailey Method analysis should be used as an additional tool to develop and select trial blends for the design of dense-graded mixes. The study noted that the Bailey Method design process led to extremely fine mixes not common in Oregon. Additional sieves were recommended to be included to allow for the development of additional ratios.
