00865.00 882 Section 00865 - Longitudinal Pavement Markings - Durable
Description
00865.00Scope - In addition to the requirements of Section 00850, install durable longitudinal
pavement markings according to the following Specifications.
Labor
00865.30Manufacturer 's Representative - Provide a manufacturer's representative according
to 00850.30.
00865.31Manufacturer -Certified Installers - Provide certified installer's according to 00850.31
Construction
00865.40General - Before installing, and in the presence of the Engineer, conduct a performance
test by applying a 150 foot test section on roofing felt. Do not place permanent Material without the Engineer's approval of the performance test. Additional performance tests may be required. Conduct performance tests at no additional cost to the Agency.
00865.45Installation - Place durable markings only when the manufacturer's representative
determines that the Pavement is ready for the pavement marking M aterial.
Apply reflective elements at a rate to obtain the following minimum initial retroreflectivity readings:
• White - 250 mcd/m 2/lx • Yellow - 200 mcd/m2/lx Apply marking M aterials by one or more of the following methods:
• Method A: Extruded Markings - Apply markings with an extrusion or ribbon type process and according to the following: For grooved markings, grind the slot depth as shown. Apply the specified marking M aterial centered in the slot as shown. The top of the marking shall be flat or slightly convex. • For profiled markings, place lines a nd bumps straight and square.
• Method B: Spray Markings - Apply two separate applications of spray markings with each application being one half the total specified thickness. Retrace the second application directly over the first application within 1/16 inch. For white colored markings, apply the second application in the same direction of the first application. For yellow colored markings that delineate two-way traffic, apply the second application in the opposite direction of the first application. For yellow colored markings on one-way Roadways, apply the second application in the same direction of the first application. Thermoplastic spray markings may be installed in one application at the total specified thickness if approved by the Engineer and after a successful performance test according to 00865.40. Apply spray markings in two applications if installing yellow colored markings over rumble strips.
• Method C: Pavement Marking Tape - Do not place tape continuously on longitudinal Pavement joints. Apply pavement marking tape as follows:
• Rolled-In Installation - Apply the tape to the fresh asphalt concrete surface prior to the final rolling of the mat. Roll the tape into the fresh surface during the finishing of the mat.
00865.75 883 • Grooved Installation - Grind slot depth to 130 to 150 mils with a smooth, uniform, and flat bottom. Apply tape into slot.
Method D: Wet Weather Markings - Apply markings with an extrusion, ribbon, or spray process and according to the following:
For grooved markings, grind t he slot depth as shown. Apply the specified marking material centered in the slot as shown. The top of the marking shall be flat or slightly convex. For profiled markings, apply markings with an extrusion or ribbon process. Place lines and bumps straight and square.
• Method AB: Non -Profiled Extruded or Sprayed Markings - Install Method A surface, non-profiled markings or Method B markings.
00865.75Manufacturer Warranty - Furnish a manufacturer warranty that unconditionally warrants
to the Agency the product(s) and installation under this Section against failure, according to this Subsection and 00170.85(c)(1). Use Agency -supplied warranty forms, available from the Engineer. "Unconditionally warrant" means that the warranty covers all failures, regardless of the source or cause of the failure, including, without limitation, whether the source or cause is or may be related to workmanship, inspection, or choice of M aterials.
The Agency inspection of any portion of the Work during the Contract and during the product installation, the Agency acceptance of the Work , corrections under the warranty, or expiration of the warranty shall not relieve the obligations under this warranty.
and 4 years all other methods and M aterials in this Section.
Loss of Retroreflectivity - Markings fail to maintain a minimum retroreflectivity of 150 mcd/m2/lx for white and 125 mcd/m2/lx for yellow. Insufficient Color Stability (Yellow) - Yellow markings fail to meet ASTM D6628. Insufficient Color Stability (W hite) - White markings fail to meet ASTM D6628 . Loss of Adhesion - Any 300-foot segment of marking shows 5 percent or greater loss of line due to non -adhesion. This constitutes a failure of that segment.
additional cost to the Agency:
Repair or replace, at the discretion of the Engineer all failed pavement markings within 6 months of the Agency's request to do so. Use Materials and procedures meeting the Specifications. Match repairs to adjoining Work . Coordinate timing of repair Work with the Engineer.
cause a hazard, the failure may be temporarily corrected by Agency or other forces at no additional cost to the Agency. Replace temporary repairs with permanent repairs at no additional cost to the Agency and according to the Specifications and within the time specified in 00865.75(c).
00865.80 884 Measurement
00865.80Measurement - The quantity of durable longitudinal pavement markings will be measured
on the length basis. Durable longitudinal pavement markings will be based on a nominal line width of 4 inches. If the width of the line is other than 4 inches, measurement will be adjusted by converting to an equivalent length of nominal 4 inch line on a proportionate area basis. Measurement will be the actual stripe. Gaps between skip stripes will not be measured.
Payment
00865.90Payment - The accepted quantities of Work performed under this Section will be paid for
at the Contract unit price, per unit of measurement, for the following items:
Pay Item Unit of Measurement

Method B (Sprayed)
Method C (Pavement Marking Tape)
Method D (Wet Weather Markings)
Method AB (Non -Profiled Extruded or S prayed)
In items (a) and (b), the word "Surface" or "Grooved" will be inserted in the first blank and the word "Profiled" or "Non-Profiled" will be inserted in the second blank.
In items (e) and (f), "Rolled-In" or "Grooved" will be inserted in the first blank and "Patterned" or "Non -Patterned" will be inserted in the second blank.
