What quality control tests are required before shipping CSS-1H asphalt emulsion to site?

Typical QC includes viscosity at specified temperature, residue or solids content, sieve residue to confirm no large particles, storage stability, and demulsibility or similar stability related tests depending on the standard. Many specs also include pH and particle charge verification for cationic systems, plus density checks for rate calculations. Producers often retain samples and issue a COA per batch. For contractor risk control, it is useful to confirm that the plant performs routine calibration of lab instruments and can provide trend data showing consistent production over time, not just a single passing test.
