    Grade selection starts with the construction method: tack coat, prime coat, surface dressing, slurry seal, cold mix, recycling, or waterproofing. Each method requires a specific setting rate and viscosity window. Next, match ionic type to aggregate chemistry and substrate characteristics. Then validate residue performance requirements such as penetration, softening point, elastic recovery, and adhesion. Finally, ensure the selected grade fits your equipment, storage, and climate constraints. In procurement, selection is formalized by referencing the exact standard grade and acceptance tests, then confirming compatibility through coating and breaking tests using local aggregates and water.
