Is the Bailey Method only a tool for the mix design lab?
No, remember the method analyzes the overall aggregate gradation in the mixture. Consequently, the principles also work on production mix to predict how changes in aggregate gradations going into the plant will affect the overall mixture volumetrics coming out of the plant. This will allow the Quality Control technician to make the necessary gradation changes to keep the mixture within specification. Can anyone learn the techniques? Yes, and to get the technology in the hands of those who need to analyze mixtures, the Asphalt Institute has developed a one-day Bailey Method Workshop entitled, The Practical Guide to Achieving HMA Volumetrics. The class is taught by the Field Engineering staff of the Institute, and is intended to provide the participants with the ability to predict the packing properties of their own individual aggregates. The information from this class will allow the participants to immediately begin to evaluate their existing mixtures and laboratory blends using the pr
