How does bitumen emulsion composition influence storage life and breaking behavior on aggregates?

Composition controls droplet stability and how the emulsion interacts with aggregate surfaces. Emulsifier type and dose determine charge and stability margin, while residue content affects viscosity and film build. pH and water chemistry influence electrostatic stability and breaking rate. Additives like polymers, latex, or stabilizers can improve adhesion and flexibility but may reduce storage stability if not balanced. On aggregates, composition determines wetting and break timing, so the same emulsion can perform differently on different rock types. Longer storage life generally requires a stronger stability margin, which must be balanced against required breaking speed in the field.
