Asphalt Rubber Methods of adding rubber to asphalt – Wet Process – rubber is added to the liquid asphalt binder before being mixed at the hot mix asphalt plant (i.e., rubber is wet before mixing) – Dry Process – rubber is added at the same time the asphal

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 di
