Slurry seal needs an emulsion that supports mixing stability, controlled breaking in the mixer and after placement, and strong adhesion to the existing surface. Key properties include suitable setting grade, consistent binder content, workable viscosity, good coating of aggregate, and resistance to premature breaking during mixing. Residue should provide durability, abrasion resistance, and water resistance. Compatibility with filler and aggregate gradation is critical, as is curing behavior under local temperature and humidity. Producers should validate with lab mix design and field trial sections to confirm set time and traffic opening time.
