PREFORMED PAVEMENT MARKING TAPE SECTION 864

559 SECTION 864 – PREFORMED PAVEMENT MARKING TAPE

864.1Description.

This work consists of providing and installing preformed pavement marking tape.

864.2Materials.

A.Preformed Pavement Marking Tape Section 1071.5

864.3Construction.

864.3.1 Submittals.

A.Submit the following items to the engineer:

1.Submit documentation from the pavement marking tape manufacturer certifying that the

contractor is trained to install the pavement marking tape before tape placement starts.

2.Submit documentation for personnel verifying a minimum 5 -years of experience in using and

placing the material before tape placement starts.

3.Submit a schedule of operations for the engineer’s approval before starting any pavement

marking work. Submit the schedule 2 -weeks before the striping application. 864.3.2 Pavement marking layout.

A.Perform pavement marking layout as needed to ensure accurate placement. Ensure the marking

method used is compatible with the pavement marking tape.

B.Offset longitudinal lines at least 2 -inches from longitudinal pavement joints or seams.

C.Offset longitudinal lines at least 2 -inches to the inside of shoulder breaks of pavement.

864.3.3 Application.

A.General application requirements.

1.Evaluate the existing pavement surface for placement suitability before performing the work.

Notify the engineer of existing permanent markings and of deteriorated pavement surfaces. Perform remedial actions as directed by the engineer.

2.Ensure ambient and surface temperatures are at least 40 F and rising, and in accordance with

the manufacturer's recommendations. If the manufacturer recommended temperature requirement for the pavement marking material application deviates from these speci fications, the manufacturer's recommendations shall hold priority. Confirm the atmospheric and pavement surface conditions with the engineer prior to starting work.

3.Unless directed otherwise by the engineer, provide a manufacturer’s representative, or qualified

personnel, onsite to oversee all operations and to ensure successful installation of markings, to provide training and product information, and to problem solv e as directed by the engineer.

4.Place a butt splice at the end of pavement marking tape rolls. Do not overlap tape.

PREFORMED PAVEMENT MARKING TAPE SECTION 864

560 5. Place a quality control strip as directed by the engineer at the beginning of each day’s operations to demonstrate that the application equipment is working properly and applying markings as required. Repeat the demonstration whenever there is a change in equipment settings or as directed by the engineer when the quality of the line being applied is in question. Authorization to proceed will be given by the engineer when the quality control test indicates conformance. If the application of the control strip is on the actual roadway, correct any application that is not in compliance with the contract.

6.Apply pavement marking material in accordance with the contract and the manufacturer’s

recommendations. Apply in accordance with the following provisions unless approved otherwise by the engineer.

a.Fresh bituminous concrete.

i.Install using the inlay method during the final rolling in accordance with the manufacturer’s

recommendations. ii. Placement of the final pavement lift is not permitted until the striping crew, pavement marking material, and equipment are on site. iii. Inlay the tape into the pavement surface with a finish roller without vibration.

b.Placement on new PCC pavement.

i.Apply the marking tape only after the concrete has adequately cured as determined by the

engineer. ii. Clean pavement surface of oil, surface treatment, curing compound, dirt, grease, concrete laitance, and other contaminants to a width at least 4 -inches wider than the marking to be applied. iii. Use a surface preparation adhesive or primer as recommended by the manufacturer. iv. Apply pavement marking material in accordance with the contract and the manufacturer’s recommendations.

c.Placement on existing pavement.

i.Clean pavement surface of oil, surface treatment, curing compound, dirt, grease, concrete

laitance, and other contaminants to a width at least 4 -inches wider than the marking to be applied. ii. Use a surface preparation adhesive or primer as recommended by the manufacturer. iii. Apply pavement marking material in accordance with the contract and the manufacturer’s recommendations.

B.All necessary markings shall be installed before the end of the workday. Install the markings as

soon as possible after weather interrupts the work.

C.Remove existing pavement markings that conflict with new or altered traffic patterns as well as

any layout markings installed that detract from the overall appearance or function of pavement markings in accordance with Section 868.

D.Request engineer to perform retroreflectivity testing once pavement marking at the location is

complete.

PREFORMED PAVEMENT MARKING TAPE SECTION 864

561 864.3.4 Furnish Warranty.

A.Provide the engineer the completed manufacturer’s warranty.

B.Provide certification to the engineer that the work was performed in accordance with

manufacturer’s recommendations. 864.3.5 Evaluation and Correction.

A.The engineer will evaluate the pavement markings for defects after an observation period of 180 -

days from the date the pavement is opened to traffic. Time charges will not be assessed during the observation period provided all other work is complete. The engineer may waive a portion or all of the 180 -day observation period.

B.The engineer will inform the contractor of pavement markings that have failed and that require

corrective action.

C.Correct pavement marking defects as directed by the engineer within 30 -days of receiving written

notification. Examples of pavement marking defects for preformed pavement marking tape include:

1.Insufficient retroreflectivty.

2.Damage caused by a vehicle tracking over uncured pavement marking material.

3.Any substrate beneath in -laid pavement marking tape is exposed due to film loss.

4.More than 5 percent exposure of substrate in any 2000 -foot section of longitudinal marking

when applied by methods other than the in -laid method.

5.Less than 90 percent of material remaining for each individual symbol, transverse pavement

marking, or legends applied by methods other than the in -laid method.

6.Discolored marking when compared visually with color chips.

7.Longitudinal marking is more than 2 -inches out of place.

8.Insufficient pavement marking thickness.

9.Pavement marking variations more than 3/8 -inch from alignment within any 40 -foot section of

traveled way.
