Which physical and chemical characteristics define high-performance bitumen emulsions?

High performance is defined by consistent residue content, stable particle size distribution, controlled breaking time, and strong adhesion to the intended aggregate or substrate. Key physical metrics include viscosity at specified temperature, storage stability, settlement tendency, and sprayability. Chemical indicators include pH window, particle charge, emulsifier compatibility, and low contamination levels. For advanced grades, you also look at elastic recovery, softening behavior of residue, cohesion development, and moisture susceptibility performance on aggregates under real field conditions.
