Asphalt emulsions have made the manufacturing, storage, and road construction a much simpler process. Asphalt emulsions are droplets of asphalt dispersed in water with the aid of an emulsifying agent. Particle size of the asphalt droplets is critical to stability and application performance. Summary Asphalt-aggregate roads have traditionally been made by an asphalt- coated aggregate hot-mixed at a central plant. Continued development of as
