The slurry seal must build sufficient cohesion to resist abrasion due to traffic. Otherwise, it will ravel off quickly, particularly in high stress areas. Early stone shedding is normal, but should not exceed 3%. General rule of thumb for a slurry seal is that it can be opened to traffic when it has turned black.

A slurry seal is the application of a mixture of water, asphalt emulsion, aggregate (very small crushed rock), and additives to an existing asphalt pavement surface. A slurry seal is similar to a fog seal except the slurry seal has aggregates as part of the mixture. This combined mixture of the emulsion and aggregates represents "slurry.".

Slurry seal is a mixture of aggregate, asphalt emulsion, and filler, which are mixed together according to a laboratory's design-mix formula. water is also added for workability. Asphalt emulsions serve as a binder, holding the crushed aggregate together and adhering the new slurry surfacing to the old surface over which it is being applied.
