What technical inaccuracies in general sources should buyers verify when selecting cationic bitumen emulsions?

[Sigfried]

General sources often oversimplify “cationic emulsion” as a single product. Buyers should verify the actual grade and setting class, binder content, viscosity method and limits, particle charge method, and residue performance requirements. Many generic pages ignore pH control ranges, water chemistry sensitivity, and compatibility with local aggregates. They also rarely mention that pump shear, contamination, and temperature excursions can trigger premature breaking. Before ordering, require the supplier COA, referenced test methods, storage stability limits, and a field compatibility test plan with your aggregates and spray equipment.
