Focus on parameters that predict field performance and storage safety. Typical acceptance tests include binder residue, viscosity at specified temperature, sieve content, storage stability, pH, and for cationic grades particle charge or equivalent compatibility indicators. Some contracts also require breaking behavior and coating tests using the project aggregate. Check appearance for separation or coagulated lumps and confirm temperature at delivery is within agreed limits. Require batch certificate matching the delivery tank or truck, plus traceable sampling and retesting procedure for disputes.
