00855.40 Pavement Markers :
a.General - Install reflective (Type I) and nonreflective (Type II) markers as shown.
b.Surface Preparation - Remove contaminants from the wearing Course surface which would adversely affect the bond of the adhesive. Sandblast or steel shot blast the Pavement surface to remove all surface contaminants. Use a blast of clean air to remove all loose particles fr om the surface.
c.Installation - Apply pavement markers to a clean, dry surface. Do not install markers spanning a Pavement joint or crack. To avoid longitudinal cracks and joints, adjust pavement markers up to one half the width of the marker. To a void transverse cracks and joints, adjust pavement markers ahead or back on line ± 5 inches. Place the adhesive uniformly on the prepared Pavement surface or on the bottom of the marker in a quantity sufficient to result in a complete coverage of the area of contact of the marker with no voids present and a slight excess of Material after the marker has been pressed in place. Place the marker in position and apply pressure until firm contact is made with the Pavement . Visually inspect the installation to ensure that a small bead approximately 1/8 inch thick forms around all edges and corners and the marker is fully supported on a pad of adhesive. Immediately remove excessive adhesive on the Pavement , and adhesive on the exposed surfaces of the markers. Completely remove adhesive from the surfaces of pavement markers using an approved adhesive remover.
