• Apply two separate applications of painted longitudinal pavement markings. Retrace the second application directly over the fi rst application, within 1/16 inch as follows: • Apply the second application after 2 hours but within 48 hours of the first application. • For yellow colored markings that delineate two-way traffic, apply the second application in the opposite direction of the first application. For yellow colored markings on one-way Roadways, apply the second application in the same direction of the first application. For white colored markings, apply the second application in the same direction of the first application. • Apply each painted marking application at a thickness of 15 mils wet, equivalent to 17 gallons per mile for a 4 inch wide solid stripe. • Apply reflective elements for each application at a minimum rate of 5 pounds per gallon of paint. Embed, by means of paint wicking, a minimum of 80 percent of the reflective elements in the paint to a minimum depth of 50 percent of their diameter. Minimum initial retroreflectivity shall be the following:
• White - 250 mcd/m 2/lx • Yellow - 200 mcd/m2/lx
