What are the core components of a bitumen emulsion and how does each affect performance?

Core components are bitumen binder, water, emulsifier package, and pH control agents, often with stabilizers or modifiers. Bitumen type and content drive residue strength, flexibility, and temperature susceptibility. Water phase chemistry controls viscosity, stability, and breaking time. Emulsifier type and dosage determine droplet charge, adhesion to aggregates, and compatibility with mineral surfaces. pH and salts tune stability and how fast the emulsion breaks under field conditions. Optional polymers or rubber improve elasticity and crack resistance but increase process sensitivity.
