00866.75 885 Section 00866 - Longitudinal Pavement Markings - High Performance
Description
00866.00Scope - In addition to the requirements of Section 00850, install high performance
longitudinal pavement markings according to the following Specifications.
Labor
00866.30Manufacturer's Representative - Provide a manufacturer's representative according
to 00850.30.
00866.31Manufacturer -Certified Installers - Provide certified installer's according to 00850.31
Construction
00866.40General - 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.
00866.45Installation - Place markings only when the manufacturer's representative determines that
the Pavement is ready for the pavement marking Material.
Do not place th e pavement markings on longitudinal Pavement joints.
Apply reflective elements at a rate to obtain the following minimum initial reflectivity readings:
• White - 250 mcd/m 2/lx • Yellow - 200 mcd/m2/lx
Apply marking M aterial by one or more of the following methods:
• Method 1: Extruded Markings - Apply markings with an extrusion or ribbon type process.
• Method 2: Sprayed Markings - If more than one application is required to obtain the specified thickness, retrace additional applications directly over previous applications within 1/16 inch.
• Method 1-2: Extruded or Sprayed Markings - Install Method 1 markings or Method 2 markings.
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.
00866.75Manufacturer Warranty - Furnish a manufacturer warranty that unconditionally warrants
to the Agency the pr oduct(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, regardl ess 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. 00866.80 886
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 (White) - White markings fail to meet ASTM D6628.
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 00866.75(c).
Measurement
00866.80Measurement - The quantities of high performance pavement markings will be measured
on the length basis. High performance 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 adjus ted 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.
00866.90 887 Payment
00866.90Payment - 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 1 (Extruded)
Method 2 (Sprayed)
Method 1 -2 (Extruded or Sprayed)
The word “Surface” or “Grooved” will be inserted in the blank.
Payment will be payment in full for furnishing and placing all Materials, and for furnishingal l Equipment , labor, and Incidentals necessary to complete the Work as specified.
Payment for Work under this Section will be limited to 75 percent of the amount due until the Agency has received the signed Warranty.
