The resulting product, emulsion-treated base (ETB), may then be surfaced with a wearing course for trafficking. Several studies have been performed to assess the long-term strength of ETB in the field.

Base Stabilization – McAsphalt

Base Stabilization. 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.
