Abstract
Disclosed is an asphalt composition to which a water soluble prepolymer which is resinified while the reaction proceeds gradually in the aqueous solution is added, wherein the strength of the asphalt composition is notably improved. Further, the resinification speed can freely be controlled by the action of a resinification accelerator. Accordingly, the additive for the emulsified asphalt and the asphalt composition for blending at cold temperatures can be applied effectively to various applications such as road pavement, railroad, waterproof agents, and adhesives.
