What are the formulation and breaking characteristics that distinguish CSS-1 bitumen emulsion in field applications?

CSS-1 is a cationic slow setting emulsion designed to remain stable during mixing and placement. It breaks gradually, allowing good coating of aggregates and extended workability. Formulation emphasizes emulsifier systems that resist premature break while maintaining strong adhesion after cure. It is commonly used in slurry seals and mixes where controlled break and uniform coating are critical.
