Mix Design Fundamentals HMA consists of two basic ingredients: aggregate and asphalt binder. HMA mix design is the process of determining what aggregate to use, what asphalt binder to use and what the optimum combination of these two ingredients ought to be. There are several different methods used to . CALCULATIONS FOR THE MARSHALL MIX DESIGN OF BITUMINOUS MIXTURES 1. Calculate the limiting asphalt content at the tentative design asphalt content. (P'b max) Calculate the Bearing Capacity for each asphalt content. 3. Bulk specific gravity of compacted paving mixture sample.
