What laboratory and field tests are mandatory for quality control of bitumen emulsions before dispatch?

[José Mari]

A practical mandatory set usually includes residue content, viscosity at specified temperature, storage stability or settlement, pH, particle charge or identification, sieve residue, and breaking behavior indicators relevant to the grade. Many buyers also require adhesion or coating tests on local aggregate and demulsibility or mixing stability checks for slow setting products. Field verification often includes sprayer calibration checks and a small trial section to confirm break time and bond. The exact list depends on the specification, but dispatch without core stability and residue confirmation is risky.
