How is Slurry Applied?
Slurry seal is applied to an existing pavement surface by means of a spreader box linked to the surface slurry-mixing unit. Slurry is introduced into the spreader box, which then lays down the slurry coating as the mixer/spreader is driven forward. The box is capable of spreading the slurry seal over the width of a traffic lane in a single pass, and is constructed so that close contact with the existing surface is maintained. This insures uniform application of the new coating on a variety of configurations encompassing various crowd shapes, superelevated sections, and shoulder slopes. Trained operators continually monitor the automatic mixing procedure. Other personnel clean the surface before slurry applications, barricade the street, inspect the operation in progress for uniformity, clean metal utility covers after application, and complete slurry seal spreading in any area inaccessible to the spreader box. Types of Slurry Emulsions of varying composition and setting times are mixed
