Restripe Faded Pavement Markings Rev. 05-09-16

PART 1: GENERAL

1-1 DESCRIPTION OF WORK: Work includes furnishing all labor, materials and equipment necessary to install pavement markings in accordance with these contract specifications, along a portion of the Virginia section of the Blue Ridge Parkway. This project represents a shift from restriping with a standard acrylic waterborne paint to restriping with a more durable waterborne acrylic paint with 100% acrylic emulsion cross-linking resins. This change will allow a thicker mil thickness of paint to be applied and use of the larger size glass beads for enhanced durability and reflectivity. Included in the work is all traffic control measures, layout of work and surface preparation required to install the following traffic markings. All work shall be performed under a single contract.

A. BASE BID: In accordance with these specifications, install approximately

899,000 linear feet (LF) of retro-reflective yellow painted centerline striping and approximately 6,100 LF of white non-reflective parking lot striping along the Blue Ridge Parkway roadway, at the following locations:

1. Milepost 106.1 to Milepost 121.4 (Section 1M) yellow retro-reflective centerline striping and 2,651 LF of white non-reflective striping at pull off parking and edgelines.

2. Mill Mountain Spur Road (starting near Milepost 120.4 and extending approximately 2.3 miles) yellow retro-reflective centerline striping.

3. Milepost 121.4 to Milepost 136.1 (Section 1N) yellow retro-reflective centerline striping.

4. Milepost 136.1 to Milepost 144.2 (Section 1P) yellow retro-reflective centerline striping.

5. Milepost 144.2 to Milepost 155.3 (Section 1Q) yellow retro-reflective centerline striping.

6. Milepost 155.3 to Milepost 165.4 (Section 1R) yellow retro-reflective centerline striping.

7. Milepost 165.4 to Milepost 174.0 (Section 1S) yellow retro-reflective centerline striping and 1,932 LF of white non-reflective striping at pull off parking and edgelines.

8. Milepost 174.0 to Milepost 183.5 (Section 1T) yellow retro-reflective centerline striping and 217 LF of white non-reflective striping at pull off parking and edgelines.

9. Milepost 183.5 to Milepost 193.3 (Section 1U) yellow retro-reflective centerline striping and 1,281 LF of white non-reflective striping at pull off parking and edgelines.
