Which laboratory test methods are used to evaluate stability and breaking behavior of bitumen emulsions?

Common methods include storage stability tests over defined time, sieve residue to detect coarse particles, viscosity at specified temperatures, pH measurement, residue by evaporation or distillation, and demulsibility or breaking tests depending on grade. Particle charge tests help confirm emulsion type and aggregate compatibility. For field performance, coating and adhesion tests with local aggregates are used to predict breaking behavior and final bonding under real site conditions.
