Installation Preparatory Work:
The asphalt surface must be structurally sound, surface cured, and free from all loose or foreign matter prior to the application.
Methods:
Place with mechanical equipment specifically designed for this purpose. Due to the heavy bodied nature of the slurry-mixed, application by means of specialized equipment is required. This equipment can be of two types, high volume positive displacement airless spray or mechanical squeegee. Both types must be capable of keeping material thoroughly mixed and homogenous throughout the application process by continuous agitation. All equipment used must be capable of supplying a sufficient quantity of material for uniform application over the entire width of the application mechanism to provide a uniformly coated surface.
