Course
Synopsis and Agenda for
An Introduction to the Bailey Method;
Achieving Volumetrics and Compactability
This one-day course will be of most benefit to those who already have a good grasp of hot-mix asphalt mix design and want to learn how to optimize volumetrics and field compactability. The Bailey Method and its four principles are introduced to understand how aggregate properties affect aggregate packing. The AI Basic Analysis Spreadsheet provided with this course will enable the participant to predict the magnitude and direction of changes in VMA based on changes to a mix design gradation or gradation fluctuations in plant produced mix. As a result, this course information can become a valuable asset to evaluate existing mixtures and in a quality control program.

This introductory one-day course will focus on the practical, “day to day” aspects of the Bailey Method. By utilizing the AI Basic Analysis Spreadsheet, the participant should be able to start utilizing the Bailey Method principles in their work.
For a more thorough understanding and application of the Bailey Method, along with a complete set of Volume Blending and Voids & VMA Estimating analysis spreadsheets, the Asphalt Institute offers a full 3-day Achieving Volumetrics and HMA Compactability Course held at headquarters in Lexington, KY.
