    In production, run routine lab tests such as residue, viscosity, pH, sieve residue, and storage stability, plus particle charge for cationic or anionic confirmation. For road application, field checks include sprayer calibration, transverse distribution tests, and verification of applied residual binder rate. Aggregate coating and break behavior tests help ensure compatibility. Densities can be tracked for quick detection of dilution or air entrainment. Acceptance at site often includes sampling and repeat QC tests to confirm the delivered batch matches the certificate. Mandatory lists depend on the governing standard and contract requirements.
