854.05 Traffic Stripe (Paint)
854.01 Description
This work consists of providing and placing a white or yellow paint stripe with beads applied by the drop -on method.
854.02 Materials
Provide materials in accordance with Subsection 711.05, “Glass Beads for Traffic Paint and Thermoplastic ” and Subsection 711.06, “Traffic Stripe Paint – Acrylic Waterborne.”
854.03 Equipment
Use a paint machine cap able of applying an even, clean -cut line with minimal drifting paint. Ensure the cutoff mechanism on the paint machine is capable of making a clean -cut end section without dripping or stringing fine lines of paint. Use a bead dispenser with an automatic c utoff control synchronized with the cutoff of the striping material.
854.04 Construction Methods
Sweep the pavement area of foreign material to ensure maximum adhesion of paint. Apply the material to the pavement at a wet film thickness of 15 mils [0.381 mm]. Evenly distribute a minimum of 6 lb of beads per gallon of wet paint [719 kg per cubic meter], unless otherwise directed by the Resident Engineer. Use an automatic bead dispenser attached to the striping machine to immediately and uniformly dispense the beads on the completed paint line. Do not apply the traffic stripe paint on wet pavement. Apply traffic stripe paint when air temperature is 50°F [10°C], and rising.
854.05 Method of Measuremen T
The Resident Engineer will measure the length of traffic stripe using a 4 in [100 mm] standard width. For traffic stripes narrower or wider than 4 in [100 mm], the Resident Engineer will make a proportional adjustment based on the 4 in [100 mm] standard width. The Resident Engineer will measure arrows, words, and symbols by each unit. The Resident Engineer will count arrows by each head. TRAFFIC STRIPE (PLASTIC) 855.02
