January 1, 2017

B. Apply Pavement marking paint at the following wet mil thickness:

1. 20-25 wet mils for all longitudinal markings.

2. Approximate application rate for required mil thickness requirements:

a. 4 inch Solid Line – From 190 to 240 ft/gal

b. 4 inch Broken Line – From 760 to 960 ft/gal

c. 8 inch Solid Line – From 95 to 120 ft/gal. Use the following calculation to determine wet mil thickness if approximation is outside the range for the desired line type.

Calculation – Determine wet mil thickness

4 inch Solid Line – Wet mils = 4812.516 ft3/gal mil/ft X ft/gal

4 inch Broken Line – Wet mils = 19250.064 ft3/gal mil/ft X ft/gal

8 inch Solid Line – Wet mils = 2406.258 ft3/gal mil/ft X ft/gal

Where:

X = application rate. (Meter readings or dipping tanks).

C. Refer to Table 1 for price reduction of pavement markings that are less than required wet mils in thickness.

D. No additional payment for pavement markings placed in excess of required wet mils in thickness or exceeding dimensional requirements outlined in this Section, Article 3.2 paragraph B.

E. Glass Sphere (Beads) – Apply at least 8 lb/gal of paint, the full length and width of line and pavement markings.

1. Calibrate bead guns and measure bead distribution according to

UDOT Materials Manual of Instruction 932, Procedure for Sampling and Accepting Pavement Marking Paint and Beads.

2. Do not apply glass beads to contrast lines (black paint).

F. Begin striping operations no later than 24 hours after notification by the Engineer.
