  • HMA Mix Design Fundamentals

    HMA consists of two basic ingredients: aggregate and asphalt binderHMA 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 When aggregate and asphalt binder are combined to produce a homogenous substance, that substance, HMA, takes on new physical properties that are related to but.
