EXECUTION

GENERAL

D. The Contractor shall be responsible for preliminary spotting of the lines to be painted and approval by the Contracting Officer must be obtained before applying pavement-marking paint.

At least 7 days before applying pavement markings, furnish a written copy of the marking Manufacturer’s recommendations for use. A field demonstration may be required to verify the adequacy of recommendations.

E. Sweep and clean surface to eliminate all loose material including: pine needles, pine straws, moss, pollen, grass, loose soils, dust etc. The area to be painted shall be dry, clean, and free of loose particles. Remove loose particles, dirt, tar, grease, and other deleterious material from the surface to be marked. Remove temporary pavement markings the same day permanent pavement markings are applied. Apply markings to a clean, dry surface according to the MUTCD.

F. Apply paint with mechanical equipment to produce pavement markings, of required dimensions, with uniform, straight edges. Apply at manufacturer's recommended rates to provide a minimum wet film thickness of 15 mils (0.4 mm). The equipment shall include a mechanical bead dispenser that will distribute the glass beads uniformly into the wet pavement markings at a rate of 6 lb/gal. (0.72 kg/L).

G. Stripes shall be 4 inches wide. Broken line segments (dashed or skip traffic strip) shall be 10 feet in length with 30-foot gaps, or 2 feet in length with 4-foot gaps.

H. Arrows and letters shall be of the dimensions as shown on the drawings or existing pavement markings.

I. The painted area shall be protected from traffic until the paint is thoroughly dry. Protect marked areas from traffic until the markings are dried to no-tracking condition. Remove all tracking marks, spilled marking material, markings in unauthorized areas, and defective markings.

J. All markings shall present a clean-cut, uniform appearance. All markings which fail to have a uniform appearance, either day or night, shall be corrected by the Contractor.

DISPOSAL

Dispose of debris and unsuitable and excess material as follows:

(1) Remove or dispose of material legally off the project Contractor shall dispose of all hazardous materials according to Federal, State, and local regulations.
