What stabilisation techniques are used to prevent premature breaking of bitumen emulsions?

[Gianmarco]

Stability depends on emulsifier choice, correct pH window, controlled ionic strength, and consistent droplet size distribution from the mill. Stabilization techniques include buffering the aqueous phase, using stabilizers or protective colloids, controlling temperature to prevent viscosity spikes, and maintaining clean lines to avoid contamination by cement, lime, salts, or incompatible residues. Gentle agitation and low shear transfer prevent coalescence. For long haul logistics, storage stability tests and transport simulation are essential. In production, inline density and viscosity monitoring helps catch off ratio dosing before a batch is dispatched.
