Two slurry products can be distinguished slurry seal and microsurfacing Slurry seal is normally laid no thicker than 1½ times the top size of the aggregate, which can range from 310 mm Mineral fillers like cement or hydrated lime are commonly used, but are not always required Slurry seals waterproof and seal the surfaceMicrosurfacing is similar to a slurry seal except it requires a more advanced polymer modified asphaltic emulsion, a more durable fine aggregate, and a chemical additive The major difference between slurry seal and microsurfacing is in how they break or harden Slurry seal relies on evaporation of the water in the asphaltic emulsionChapter 4 Construction Details Caltrans
