Optimizing Volumetrics and HMA Compactability Utilizing the Bailey Method

Have you ever wondered why your volumetric test results were passing in the morning and failing miserably by noon? This webinar will explain several reasons why this can occur. This webinar will cover the basics of VMA and Air Voids and explain how absorption affects your results. We will discuss the Bailey Method, which is an innovative aggregate and mixture analysis system that can accurately estimate the effects of aggregate packing and how that affects mix volumetrics. The four basic principles of the Bailey Method will be introduced to help explain mysterious volumetric changes that can occur in field produced mixtures.
