Section 634.-PERMANENT PAVEMENT MARKINGS

634.01 Description.

This section is superseded with the following:

This work consists of applying permanent pavement markings and glass beads. The Contractor shall also provide temporary traffic control in accordance with Section 635.-Temporary Traffic Control and the approved traffic control plan.

634.03 General.

The first paragraph is superseded with the following:

The Government will stake the limits of the existing pavement markings (no passing zones, edge stripes, etc.) before any pavement marking work begins.

The third paragraph is superseded with the following:

At least 7 days before applying pavement markings, furnish a written copy of the marking manufacturer’s recommendations for use. A field demonstration shall be conducted one (1) day before the Contractor is authorized to place permanent pavement markings to verify the adequacy of the manufacturer’s recommendation, equipment compliance, application rates of the traffic paints and beads. The field demonstration shall be 100 feet for the white traffic paint with glass beads and 200 feet for the yellow paint with glass beads meeting the contract requirements under Subsection 634.04 through 634.08. Cease demonstration after placement of pavement markings until the demonstration is evaluated and accepted.

The field demonstration is accepted if the manufacturer’s recommendations are verified, and the application rates of the traffic paints and glass beads are within the contract specification limits.

Repeat the field demonstration until an acceptable demonstration is produced. See Subsection

106.01 for the disposition of material in unacceptable demonstration(s). Accepted field demonstration may remain in place and will be accepted and measured as a part of the completed work. When a field demonstration is accepted, full production may begin.

If the Contractor changes manufacturer or if the marking operation is producing unsatisfactory results, the field demonstration procedures shall be repeated as necessary until the desired results are achieved.

The Contractor shall ensure that all paint sampling and handling procedures are performed in accordance with the following:

1. Drums of paint shall have tamper proof seals as required under Subparagraph 634.03(b) Drum Seals.

2. The paint and bead tanks on the striping machine shall be empty, unless the Contractor provides a “Letter of Transfer for Paint” from a previous BIA/State project as required under Subparagraph 634.03(f) Letter of Transfer for Paint.

3. Settle pigment shall be redisbursed before loading paint as required under Subparagraph 634.03(a) Redisbursement of Settled Paint.

4. The Contractor shall strap the tanks as described in Subparagraph 634.03(e) Volume Control Requirements.

634.05 Waterborne Traffic Paint (Type B). Apply paint when the pavement and air temperatures are above 50 °F. Spray paint at 15 mil minimum wet film thickness before glass beads or at a rate of 107 square feet per gallon.

(a) Redisbursement of Settled Paint. When paint has settled excessively, the Contractor shall redisburse the settled pigments at the bottom of the paint drums with a mixing device before pumping or loading into the striping unit so that excess pigments are not left on the bottom to the paint drums. Thinner shall not be allowed to be pumped into the paint tanks.

(b) Drum Seals. Drums of paint used on BIA projects shall be sealed at the point of manufacture and consecutively numbered with tamper proof seals. These seals shall only be removed with a BIA representative present at the time of actual use. Drums with broken seals shall not be accepted.

(c) Equipment. The traffic paint and beads shall be placed on the pavement by a spray type, self-propelled pavement marking machine.

The machine shall be capable of applying clear-cut 4-inch lines. The machine shall be equipped with an air-operated glass bead drop-in dispenser controlled by the spray gun mechanism. The machine shall be equipped with a mechanical device capable of placing a broken reflectorized centerline stripe having a 10 feet length and 30 feet gap between stripes.

The dispenser shall be capable of placing the glass spheres into the paint line as the paint is applied to the pavement in such a manner as to provide satisfactory marking and delineation.

(d) Measurement Devices. A method of measuring the actual volume of paint and beads in the tanks shall be provided on the tanks either by strap measurement or other externally approved gauging methods.

The Contractor shall provide current certification of calibration of all painting equipment at least 7 calendar days before the field demonstration for review and approval.

(e) Volume Control Requirements. The volume of paint and glass beads in place shall be measured by the quantity per kilometer method or using paint and beads gauges.

The Contractor shall strap the tanks before beginning striping operations and again after 3,300 feet has been striped or if the striping machine is equipped with air atomized spray units (not airless) and paint and bead gauges, the volume may be determined by said gauges.

The volume shall be measured again at the beginning and end of each day. This information shall be given to the BIA Representative.

(f) Letter of Transfer for Paint. The paint and bead tanks of the striper must be empty before filling for the beginning of the striping operations for the project, unless a “Letter of Transfer for Paint” has been obtained.

Paint or glass beads left over in the striping truck tank can be transferred from one BIA project by providing a “Letter of Transfer for Paint” which shall include the following information:

1. The quantity left in the tanks.

2. The BIA project it is coming from, including the termini and project name.

3. The project it is going to.

4. The date.

5. The batch number the paint came from.

6. The seal numbers of the paint in the tank.

7. The previous responsible representative’s signature.

(g) Tolerance Requirements for Placing Paint & Beads. The finished lines shall be smooth, aesthetically acceptable, and free from undue waviness.

(h) Repairs & Replacement of Unacceptable or Damaged Striping. If paint is not adhering to the existing pavement, the Contractor shall REMOVE the striping (under an approved method) and shall RESTRIPE the existing pavement. All damage to the pavement markings because of the Contractor’s negligence or failure to maintain traffic control shall be repaired at no additional cost to the Government.
