The purpose of base stabilization is to increase the bearing capacity (or strength) of the roadbed materials. Adding an emulsified asphalt, and possibly other fillers, increases the road’s firmness and resistance to weather, while reducing movement or rutting in the base layer. Mix design work performed in the lab seeks to maximize the strength of the base materials and minimize the effects of moisture and freeze/thaw cycles.
