The Contractor is subject to fines under City ordinance for noncompliance with the Barricade Manual.

The Contractor shall schedule his work to minimize interference with traffic flow. The work order will indicate restricted work hours for each work site. All streets are to remain open to traffic during marking operations by maintaining a minimum of one lane clear of obstructions.

The Contractor shall provide flagmen and/or following trucks as required to safely control traffic. When not in use, marking equipment and machinery shall be removed from the street.

Any work allowed during night time hours shall be pre-approved by the Engineering Program Administrator of the Transportation and Public Works Division as specified in the City of Dallas Noise Variance Ordinance (Chapter 53 of the Dallas City Code can be found at:

http://dallascityhall.com/government/Pages/city-codes.aspx). If marking operations are performed during night time periods, suitable illumination of facilities for marking equipment must be provided. Approval of night time work shall be coordinated through the Traffic Markings Manager.

No work will be permitted (except in case of emergency) nor any equipment or material stored or parked on any street in the Central Business District (CBD) between the hours of 6:30 A.M. - 9:30 A.M. and 3:30 P.M. - 6:30 P.M. on normal workdays. The CBD for this purpose is defined as the area bounded by Woodall Rodgers Freeway, I.H. 30, I.H. 45, and the Trinity River. Night and weekend work will be permitted in the CBD.

a. Do not place pavement markings if the pavement temperature is below 50oF and/or the pavement fails the moisture test. Apply markings during good weather unless otherwise directed. If markings are placed at Contractor option when inclement weather is impending and the markings are damaged by subsequent precipitation or temperature, the Contractor is responsible for all costs associated with replacing the markings if required.

b. Apply markings on pavement that is completely dry and passes the following tests performed:

i. Type I Marking Application – Place a sample of Type I marking material on a piece of tarpaper placed on the pavement. Allow the material to cool to ambient temperature, and then inspect the underside of the tarpaper in contact with the pavement. Pavement will be considered dry if there is no condensation on the tarpaper.

c. Apply markings:

i. that meet the requirements of TxDOT Specification 828-B,

ii. using widths and color as shown in the work order or as directed,

iii. at locations shown on the work order,

iv. in proper alignment with the guides without deviating from the alignment more than 1 in. per 200 ft. of roadway or more than 2 in. maximum,

v. without abrupt deviations,

vi. free of blisters and with no more than 5% by area of holes or voids,

vii. with uniform cross section and thickness,

viii. with clean and reasonably square ends,

ix. that are reflective.

d. Remove all applied markings that are not in alignment or sequence as stated in the plans or as stated in the specifications at the Contractor’s expense in accordance with Sections 5.1 through 5.4 of “Eliminating Existing Pavement Markings and Markers”.

7. Type I Markings: Place the Type I marking after the sealer cures. Apply within the temperature limits recommended by the material manufacturer.

a. Apply on clean, dry pavements passing the moisture test described in Section 2.4.A, “General,” and with a surface temperature above 50 degrees F when measured in accordance with TxDOT Specification 829-B.

b. Apply Type I markings with a minimum thickness of:

c. 0.125 in. (125 mils) extrude, for new markings (install) and retracing (recapped) water-based markings on surface treatments involving TxDOT Item 316, “Surface Treatments,” or TxDOT Item 318, “Hot Asphalt-Rubber Surface Treatments,”

d. 0.125 in. (125 mils) extrude, for retracing (recapped) on thermoplastic pavement markings, or

e. 0.125 in. (125 mils) extrude, for new markings (install) and retracing (recapped) for all other Type I markings.

f. The maximum thickness for Type I markings is 0.180 in. (180 mils). Measure the thickness for markings in accordance with TxDOT Specification 854-B using the tape method.

8. Bead Coverage: For Type I markings, provide a uniform distribution of Type II drop-on glass beads across the surface of the stripe, with 40 to 60% bead embedment. Beads shall be distributed evenly across the surface.

9. Performance Period: All markings and replacement markings must meet the requirements of TxDOT Specification 828-B for at least 60 calendar days after installation. Unless otherwise directed, remove pavement markings that fail to meet these requirements, and replace at the Contractor’s expense. The Contractor shall replace failed markings within 30 days of notification.
