SS-1 is a slow-setting anionic asphalt emulsion that is designed for various paving and industrial uses. Asphalt emulsions are classified according to the electric charge that surrounds the emulsion’s asphalt particles (i.e. whether it is a cationic or an anionic emulsion) and how quickly the suspended asphalt particles separate from the surrounding water (“breaking”). A slow-setting emulsion is designed to maximize the mixing time with aggregates. Longer workability times ensure a good coating on densegraded aggregates with a high fines content. The setting speed of any emulsion is relative to atmospheric conditions at the time of construction.
